Video Transcript for Redline Trailer Brakes BP01-180 Review

Today, we're going to take a look at the replacement trailer brake magnet for the Dexter, Alko, and Hayes 12" electric trailer brakes, this part includes everything shown here on the table, the magnet itself, the spring, and the clip to hold the magnet into place. This magnet kit will allow you to replace the worn-out magnet on your 12" trailer brakes, and because you're replacing just the magnet, not the whole assembly, it will save you time and money. This part is designed to work with the following brake assemblies, it'll work with the Dexter 12" x 2" on a 6000 pound axle, the Alko 12" x 2" on the 6000 and 700 pounds axles, the after-1988, and the Hayes 12" x 2" 600 and 7000 pound axles after 1988. If you notice, the magnet is an oval design, and they do that to increase the efficiency of the magnet, and to also extend the life of the magnet. Just to give you an idea of the size on this, the width of it you can see is about 3 1/8", and the height going to be right at about 2". You also notice, when the wires come out of the magnet, they have a section of a protective sleeve over that, and the reason they do that is because, when this is installed in your brake assembly, that initial part of the wire is what goes through the backing plate, so you don't want the wires rubbing up against the backing plate and causing problems, so they put this nice, protective sleeve on here to protect the wires from getting damaged. Also, if you notice, it has the two wires, two black wires coming out of it. It doesn't matter which wire from the magnet is attached to the power or the ground, you just want to make sure that one of the wires is properly grounded, and then the other wire will be attached to your electric brake output circuit from your trailer connector.

That should do it for the review of the replacement trailer brake magnet for the Dexter, Alko, and Hayes 12" electric trailer brakes.

Replacement Trailer Brake Magnet for 12" Brake Assemblies - BP01-180

Average Customer Rating:  4.8 out of 5 stars   (35 Customer Reviews)

Everything I needed to replace the old brake magnets.



by:

I'll give a #4 for now, they were slow getting here and I only have one installed right now ! The real test is when I haul my 40' trailer down the road for a few thousand miles, then I will know how well they work.

Richard H.

They are doing exactly what they were designed to do !



by:

My trailer is very old. It is home built and the brake plates were welded on the axles and I had to turn the axles around to get the brake actuators to function in the proper manner. While I was working on it, I realized the magnets needed replacing, but the originals were of a brand I couldn't find. I managed to measure the old parts and found the correct replacement on etrailer.com at less then half the price a local trailer shop wanted for a similar part. The magnets were exactly the right part, they arrived a day sooner then I expected and the brakes are back together and functioning as advertised. Now if it would stop raining I could get the axles back under the trailer and get the brakes wired up again. I'm not complaining about the rain, and certainly am happy about the parts and quick service.

Thanks for checking back with me as I had completely forgotten the trailer brake issues I had last year. The brakes are still functioning fine and we are now using that trailer to haul logs and equipment on a regular basis with absolutely no problems with the brakes. I wish I had reworked them earlier and would recommend the parts I used to anyone with a similar issue.



by:

What I needed and got to me in time ! Easy to install. Also e-trailer has a slug of instructional videos. My brakes were sorely out of adjustment. A couple minutes reviewing the video and a few more adjusting the brakes and I'm a happy camper.

My order was correct and shipped promptly at a very reasonable shipping cost. Very satisfied with the service, I give it 5 stars



by:

Works just fine. Takes about the same effort as replacing the whole brake unit. But is cheaper. If caught early enough, you only need the clip inside.



by:

Had one ready to replace this spring - the wire on the old one had gotten caught in the brake mechanism. Glad I ordered the kit.



by:

Installation was easy and best of all they work! Many thanks to the Technical Support Team for helping me find the ones that match the trailer and troubleshoot that darn "beeping" noise coming from my truck brake controller.



by:

I thought had an issue with my wiring and after doing a little research I figured out it was more than likely due to worn magnets. I was able to locate the correct type, order, and replace the magnets fixing my problem! I saved money by installing them myself!



by:

All products bought are working perfectly. These parts are good quality for the money. And more importantly, E trailer's customer service is why I only buy my trailer parts from them.



by:

Very fast shipping, well packaged and a direct replacement for my worn magnets. Etrailer makes it easy to get the right part for my old 5th wheel.



by:

part was direct fit replacement, easy install works like the other 3 wheels.



by:

Product fairly priced, correct product shipped with the cost of shipping reasonable. Very satisfied.



by:

Magnet replaced an ALKO magnet. Same quality and design.



by:

Promptly shipped and it was the correct part.. Thanks E-Trailer, you never let me down..



by:

awesome service and fast shipping. Thank You Bunches!!

I ordered four magnets and I received them in three days as they bumped me up to a quick ship at no additional charge. Installed with no problem and they are working fine.

  • Can the Brakes On A Motorhome Axle Be Replaced?
    Since motorhome axles are considered one time use, they are not designed or intended to be used with standard trailer parts. With that being said, you're going to have to replace your axles. I know this is not what you were looking to do, however in this situation it is going to be the only viable solution for you. I'd be more than happy to assist you find what you're needing, however I am first going to need to a couple of measurements. I'm going to need the distance from the spring...

  • Troubleshooting Trailer Brakes That Stop Working When Trailer Is Hitched To Truck
    Based on your description there is an issue with the wiring running from the 7-way connector to the trailer brakes on your trailer, but I will say this is a very odd issue. I recommend tracing the trailer brake output wire from your trailers 7-way looking for any damage or any places it might be getting pinched when the trailer is hitched to your ball mount. Replace any damage sections with # 10-1-1 and heat shrink butt connectors # DW05745-5. It is likely that the wires are getting pinched...

  • Can 3500 lb AL KO Brake Assemblies be Replaced with Dexter Brake Assemblies
    Yes, the Dexter Nev-R-Adjust brakes will work with your 3,500 lb AL-KO axles. Brake assemblies attach to the brake mounting flange that is welded to the axle or spindle. The brake mounting flange on the 3,500 lb AL-KO axles uses a standard 4-bolt pattern that is compatible with AL-KO 3,500 lb brake assemblies and Dexter brake assemblies. For the left hand brake assembly, you can use part # 23-468 and for the right hand use part # 23-469. I have attached a review video for the Nev-R-Adjust...

  • How to Release Trailer Brakes After Trailer Break Away Pin Pulls Out
    If your break away switch looks like # HM20010 then you should just have to push the pin back in. This will break the circuit and release the trailer brakes. If this does not work then there is some other wiring issue going on. You will need to remove power from the system to get the brakes to release. You can do this by disconnecting the break away system battery (just remove the power wire from the positive battery terminal). After the brakes release you will want to determine the cause...

  • Will Out of Adjustment Trailer Brakes Cause a Fault Code on the Electric Trailer Brake Controller
    The brake pads themselves being out of adjustment would not cause a fault code to read on your brake controller. You can check the brake pad adjustment by safely raising the trailer and spinning the tire. If you hear a slight lining drag as the tire spins, and can easily spin the tire your brakes are properly adjusted. If the tire is hard to spin or you hear intermittent or no lining drag the brakes should be adjusted. We have a video that shows how to adjust the trailer brakes at the 4...

  • Old Hayes / AL-KO brakes Replacement Brake Magnets
    The Replacement Trailer Brake Magnet for 12" Brake Assemblies # BP01-180 will fit old Hayes AL-KO brake Assemblies that are 12x2 inches. They fit 6K and 7K assemblies after 1988. For the 7.2K and 8K oval you would want the Trailer Brake Magnet For Dexter 12-1/4 Brake Assembly, White Wire # BP01-265 instead.

  • Troubleshooting Trailer Brakes That Do Not Grab Evenly On Both Sides
    If you're certain that your trailer brakes are adjusted properly, then you likely have a wiring issue such as a short somewhere. What you can do is, start by checking the trailer wiring connector on the truck for corrosion. Corrosion can often the culprit of situations such as these. If there is corrosion on your connector, then clean the connector and check again to see if the problem persists. Next, if that did not solve your issue, then what you can do is check the wiring on the...

  • Electric Brake Assembly Recommendation
    Hubs that will fit those bearings include etrailer Trailer Hub and Drum Assembly for 3,500-lb E-Z Lube Axles 5 on 4-1/2 # AKHD-545-35-EZ-K or Trailer Hub and Drum Assembly 6 on 5-1/2 # AKHD-655-35-EZ-K depending on the bolt pattern you have. The brake assemblies part numbers # AKEBRK-35L-SA and # AKEBRK-35R-SA will then work well with the either hub referenced. These will fit 10" diameter, wheel sizes 13", 14", and 15", and are intended for 3,500 lbs axles. Included are video resources...

  • Axle Kits with Electric Brakes to Replace Mobile Home Axles
    We do carry replacement magnets and other parts for electric drum brakes, including some older designs. I linked the replacement magnets we carry for 12 x 2 brakes, parts # BP01-225 and # BP01-180. However, mobile home axles are not intended for continuous use on a trailer. Mobile home axles are manufactured to be strong enough only for one use to transport the dwelling to its destination - just that one time. Mobile home axles are not safe for ongoing use on a trailer. But we do offer...

  • Will the Dexter # BP01-225 work as a Replacement part for the # BP01-180 or BP01-185
    According to my contact at Dexter, the Dexter # BP01-225 is rated for use on up to a 7K axle and it is intended to fit Dexter and Dexter Nev-R-Adjust brake assemblies. It has a larger profile and may not fit on Hayes/Alko brake assemblies. Where as the # BP01-180, is also rated for use on up to 7K axles, and it is considered a fit for Dexter and Hayes/Alko brake assemblies. The # BP01-185 is rated for use on up to 6K axles, and is considered a fit for Dexter brake assemblies. If you...

  • Replacement Brake Magnet for 12 x 2 Inch AL-KO Electric Brakes on a 2009 Cougar 5th Wheel Trailer
    You can actually use either magnet, # BP01-180 or # AKBRKR-M12, since your trailer is well past the 1988 cutoff for AL-KO assemblies. There is no advantage of one magnet over the other so I would go with # AKBRKR-M12 since it costs less.

  • Mobile Home Trailer Axle Replacement Brake Shoes
    I will need some measurements to help me make the correct recommendation for replacement brake shoes for your mobile home. The inside diameter and the depth of the brake drum is what determines the necessary width of the brake pads. For example, the 10 inch x 2-1/4 inch Electric Brake Shoe, Item # AKEBRK-35L, would fit a brake drum with a 10 inch diameter and 2-1/4 inch depth. If you would like to get me those two measurements I would be able to help you. I have linked a picture showing...

  • Troubleshooting One Brake Locked Up on Trailer
    Sounds like there could be a short in your trailer wiring for one of the brakes or there could have been a mechanical failure in that one brake assembly. The second possibility is more likely since only one brake was affected. First inspect the wiring to the affected brake (and the others too) to check for signs of damaged wires or worn insulation that could cause a short. If the short was near the one brake assembly then that might cause the issue to be isolated to the one brake. Also...

  • Will Going with a Higher Rated Brake Magnet Give More Braking Power
    Going to a "more powerful" magnet will not give you additional stopping power. All it will do is make your trailer brakes harder to fine tune as they will want to lock up easier. Your best option would be to stick with the proper rated magnets for your setup. If your brakes are weak and won't lock up that could mean that your magnets are worn and need replaced or your assemblies are out of adjustment. The easiest possibility is that your brake controller just needs to be adjusted for more...

  • Is # BP01-225 a Replacement for # BP01-180 Brake Magnet
    According to my contacts at Redneck Trailer Supply, the less expensive BP01-225 is indeed an acceptable replacement for the BP01-180 brake magnets on your 12x2 Dexter brake assembly.

  • How to Wire Trailer Brake Magnets
    As long as one of the wires coming from the back of the hub is a ground and the other is a power, it does not matter which wire on the magnet goes to which wire from the back of the hub. I have included a link to a video of a magnetic brake replacement video that may be helpful. It is for a different size brake, but you it shows the whole process.

  • Weak Braking Performance with Electric Drum Brakes on 6000-lb Tandem Axle Sealcoating Rig
    On the Dexter Electric Brake Assembly you referenced, part # 23-105 rated for 6000-lb axles, the pad thickness varies slightly across the arc-shaped curve of the pad. I measured one with a precision digital caliper and found that pad thickness varies from 0.20-inches in the center of the pad to 0.18-inches at the ends. If your brake pads have 3/32nd-inches of pad thickness left (or 0.093-inches) then this clearly indicates wear that could, but does not necessarily, explain your weak braking...

  • Are Trailer Brakes Always On or Off When Not Connected to a Tow Vehicle
    Unless something is putting voltage on the brake output circuit of the trailer wiring the brakes of the trailer wouldn't be activated. So if your trailer wasn't plugged into a tow vehicle the trailer's brakes should not be activated unless the off-chance the breakaway system's pin has been pulled. I attached an FAQ on breakaway systems for you to check out as well as an FAQ on brake controllers that you may find helpful.

  • Trailer Brakes on 1 Axle are Weak on Tandem Axle Trailer
    Having the tires off the ground only means that the brakes just have to stop the tires from spinning and not the momentum or weight of the trailer so it is not surprising that the trouble axle seems to work fine in that scenario. Usually when brakes are weak it is because they need to be adjusted. They need to be adjusted so that you hear a slight but constant drag of the pads on the inside of the drum. To see how to manually adjust trailer brake assemblies check out the video I attached,...

  • Testing To See If Brake Magnets Are Bad
    It is not normal to have 12 volts on both wires of your magnet. One side should be hot and the other should be ground. I recommend checking your magnets for amperage using a multimeter like # PT89ZR. I've attached an article on how to use this meter to test your brake magnets. If you find that the magnets are bad, I recommend # BP01-180 for 12 inch assemblies and # AKBRKR-M10 for 10 inch assemblies.

  • If One Brake Magnet Goes Bad, Will Other Brakes Still Work?
    If one brake magnet goes out the other 3 on your trailer will still be working, you will just not have the one braking assembly working and it will need to be replaced. As long as the pads on the assembly are in good shape you can just replace the magnet using the Replacement Trailer Brake Magnet for 12" Brake Assemblies # BP01-180 if you have 12" brakes, or # AKBRKR-M10 if you have 10" 3500lb brakes. If you can let me know exactly which size brakes you have I would be happy to confirm...

  • Do Dexter Nev-R-Lube Hub and Drums Use the Same Brake Components as Other Dexter Hub and Drums
    The Dexter Nev-R-Lube Hub and Drums will use the same braking components as other Dexter Hub and Drums. You would just need to determine the size of the drum in order to determine which parts to use. The magnet you were looking at, part # BP01-180, is for 12 inch drums. The magnet you would use for 10 inch drums is part # BP01-110. Same principle applies for shoes and entire brake assemblies.

  • Recommended Drums For Hayes Axle On 1983 Carriage Conestoga Fifth Wheel Trailer
    There are a couple things going on you can check. First, your shoes may be adjusted out too far and that is what is causing the fit issue with the drum. You will want to adjust the brakes so that they are not expanded as much and see if that helps. If you are going to replace the drums you will need to know the bearing and seal sizes that fit your spindles. I have attached a photo that shows where the numbers can be found on your old bearing and seal and make sure they are a match with...

  • Replacement Trailer Brakes for Mobile Home
    Thank you for the pictures. I have a solution for you but it does not look like we have any replacement shoes or springs for the measurements you have specified. Mobile home axles are designed for one time use and replacement parts can be difficult to find. For the dimensions you've given me I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Right Hand item # 23-465, and left hand assembly item # 23-464.
