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.

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.

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..

  • Replacement Magnets for Al KO 3500 lb Trailer Brake Assemblies
    We have the part # BP01-110 which is the correct replacement magnet kit for AL KO 3,500 lb brake assemblies like you have.

  • Brake Magnets Needed for 2010 Surtrac Trailer with 5200 LB Axles
    I spoke with my contact at Dexter Axle and if there is any question regarding capacity, he recommends going with a magnet for a 7K axle brake assembly. The magnet is interchangeable so if you do indeed have brake assemblies for a 6K axle, it will still work for you. The magnet will be just a bit stronger but will not cause you any issues. Currently we offer 2 options when it comes to brake magnets for 12 inch x 2 inch brake assemblies. Trailer Brake Magnet, # BP01-180, fits: Dexter 12"...

  • Troubleshooting Electric Trailer Brake Assembly Magnets
    We have an article to assist with checking your brake magnets like you are stating. The resistance will go down because the brake magnets are connected in parallel. Since the voltage doesn't change, the amperage draw needs to increase to power the magnets. This is Ohms law in action based on my research. You obviously already have a multimeter like # PT89ZR so if you determine based on the article that you need to replace magnets, I recommend # BP01-180 for 12 inch Dexter assemblies...

  • 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.

  • Troubleshooting An Electric Drum Trailer Brake that Will Not Release On One Side
    I would start by checking to see if 12 volt power is constantly running to the right brake. If it is for some reason, trace the wiring to make sure it is connected in the right place. Also make sure the ground is attached to a clean and corrosion free bare metal surface. Then, you can go back and basically start from scratch with the installation. Make sure that everything is properly installed and that the brakes are adjusted correctly. You can also test the magnet. I would check the...

  • Availability of Replacement Round Magnet for Older Dexter 6,000 Pound Brakes
    I do have a solution for you, however we don't have a replacement brake magnet available that will work on your older 6,000 pound Dexter Axles. The round magnets you have pictured are pretty old models that aren't made anymore and the current oval design won't be compatible as replacements. With this in mind your best option at this point will be to replace the brake assemblies themselves. For 6,000 pound assemblies the Dexter Nev-R-Adjust Brake Kit # 23-458-459 will work great. Both the...

  • 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.

  • 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.

  • One Side Of Electric Trailer Brakes Are Locking Up When Braking
    There are a few things you can check to make sure the brakes are adjusted correctly, but it sounds like there may be a short in the system. I would start by checking the trailer wiring connector on the truck and trailer for corrosion. If there is corrosion in either connector, it will need to be replaced. Next, I would inspect the wiring on the trailer, for any cut or frayed wires. It is possible that maybe only one brake assembly is getting power. You will also want to check the ground...

  • Compatibility of 235/85-16 Tires With 16 x 6 Rims
    I checked with our resident tire and wheel expert, who tells me that a 235/85-16 tire can indeed be successfully used on a 6 inch wide rim. I wouldn't recommend going any narrower than that, though. I'll link you to our trailer tire help article that you might find helpful.

  • 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.

  • Replacement Brake Assembly Magnets for a Dexter 8k Axle
    The brake assemblies that are on your 8k Dexter axles most would be the Dexter Electric Brake Assembly # 23-435, the replacement brake magnets for this assembly would be the Replacement Magnet Kit # BP01-301.

  • Electric Trailer Brakes Lock Up When Trailer is Plugged in to Tow Vehicle
    The easiest first step here would be to try the trailer on a different truck, and see if the same problem occurs. If the trailer brakes are free until the trailer is plugged in, I suspect that something is mis wired. I would suggest examine the wiring where the break away system was bypassed and make sure that the 12-volt accessory feed is not connected to the brake wire at some point. Are you by chance using a 7 to 6-way adapter? If so, there are two accepted ways of wiring a 6-way connector....

  • Which Magnets are Recommended for 12 inch Dexter Trailer Brake Assemblies
    Depends on the capacity Dexter axle you have. If your 12 inch drum axles are 6k rated the magnet you would need as a replacement is the part # BP01-180. If instead you have a 7k axle the correct magnet is the part # BP01-225.

  • Getting Power To Trailer Brakes But Brakes Not Activating on 2010 322 Toy Hauler
    There are a few things that could be causing the problem you are having with your trailer brakes. First, you will want to check the adjustment to your brake assemblies. When turning the trailer wheel, you should be able to hear the brakes barely brushing all around as the wheel spins. If that is not the case you will want to adjust the brakes by accessing the adjustment gear on the back of the brakes (see video link). You will want to tighten up this gear until you cannot easily spin the...

  • Comparing Trailer Brake Magnets # BP01-225 and # BP01-180
    The Trailer Brake Magnet, # BP01-225, that you have referenced is designed for use with 12 x 2 inch Dexter electric drum brakes for 7,000 pound capacity axles. A similar magnet, # BP01-180, fits Dexter 6K, Alko 6K and 7K after 1988 (excluding centerline), and Hayes 6K and 7K after 1988 (excluding centerline) 12 x 2 inch drum brakes. Both magnets have 1 wire for ground, and 1 for power and it does not matter which wire is used for either function.

  • Power Draw of LED Indicator Lights on Trailer Breakaway Kit and Brake Controller
    I sounds like you might be asking about a Trailer Breakaway Kit like # 50-85-313 which has LED indicators to tell about the charge status of the included emergency breakaway battery. One of these indicator lights will come on as needed to tell you if the battery is already charged, in the process of charging or if it is depleted. These LED lights use only a very, very small amount of power so they present no concern about power consumption. Please refer to the linked video for more details....

  • 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.

  • What Replacement Brake Shoes and Magnets do I need for Electric Drum Brakes?
    I have some parts you need for your brakes. Unfortunately, all of our brake flanges fall under the pilot hole diameter of 4 inches. The largest one we have is 3" like the Trailer Brake Mounting Flange for 3-1/2" Axles, 12-1/4" Brake Assemblies # 4-50. This is a 4-bolt square pattern. As far as the shoes, I recommend using 2 of the Replacement Shoe and Lining Kit for Dexter 12" x 2" Electric Brake Assembly - 7,000-lb # DX28FR. For the magnets, the parts you need are the Replacement Trailer...

  • Troubleshooting Electric Brakes That Energize When Not Connected to Tow Vehicle
    Trailer electric drum brakes do make a humming sound when their magnets are energized with power from a trailer brake controller. This is normal behavior and it is usually possible to hear the energized brakes from about a foot away. If your brakes are being energized when the trailer is NOT connected to the tow vehicle this indicates an issue in the trailer wiring. Something is allowing 12V power to reach your brakes when it should not. Since the trailer is disconnected from the tow vehicle...

  • What Wiring Size Is On Replacement Trailer Brake Magnet # BP01-180?
    The Replacement Trailer Brake Magnet # BP01-180 has 16 gauge wires. Not all magnets will require the protective coverings as the brake assembly backing plate will have a Bushing similar to the # SWC8052-1 that protects the wiring from chaffing on the steel when it travels through the plate.

  • 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...

  • 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...

  • 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...
