Drum brake assemblies provide superior protection from corrosion and let you reverse without actuating. Designed for use with hydraulic brake actuators that do not include reverse lockouts. Fit most 14", 14" and 15" wheels.


Features:

  • Hydraulic drum brake assemblies are designed for use with a surge-type trailer brake actuator
  • Free-backing design lets you reverse without trailer brakes being activated
    • Hydraulic pressure is contained by wheel cylinder
    • Brake shoe turns and releases pressure when reversing
  • Galphorite plating delivers superior corrosion protection
    • Backing plate and shoe levers are sealed with permanently bonded electrocoat primer
    • Second coat of rugged acrylic is applied to backing plate - nearly rustproof
    • Wheel cylinders are treated with hot black oxide
    • Internal components are olive drab, zinc plated
    • Stainless steel springs
  • Adjuster plugs (included) cover access holes to keep dirt and grime out of the assemblies and off of the shoes
  • Left-hand (driver's-side) brake assembly and right-hand (passenger's-side) brake assembly included
    • Mounting bolts and hardware sold separately


Specs:

  • Dimensions: 10" diameter x 2-1/4" wide
  • Pad lining: 44 sq in
  • Wheel size: 14" and 15"
  • Mounting flange bolt pattern: 4 bolt

  • Center hole diameter: 3"
  • Axle rating: up to 3,750 lbs
  • 1-Year warranty
    • 2-Year corrosion warranty


The unique free-backing design, patented by DICO, lets your trailer move in reverse without actuating the brakes. When you begin backing up, the brake shoes are firm against the drum, as in a braking situation. As you continue in reverse, however, the shoes turn with the drum until the lining pressure is released and you are able to back up freely.


These brakes are designed to eliminate friction between the shoes and drum when you are driving in reverse. A trailer breakaway kit will not be effective should your trailer disconnect from your tow vehicle when backing up.

Six Stars!! Your web site shows what patience and hard work does! Awesome !! I have now ordered all trailer brake components, hoses, lines everything for a complete job. Easy to find correct parts. Called and talked to Derek to make sure i was ordering the correct parts. Shipping and handling also was great. Now install. Thank You



by:

Well this is the second time I am asked to review these meatheads, I called and spoke to a human to make sure my order will be right for my 5th wheel, the first set of brakes they sent me were the wrong ones as the bolt pattern to mount them was wrong, these were returned and after talking on the phone another 40 minutes they finally found the right ones to ship to me, well I received them and they were wrong too, so back to returns and back on the phone, another long talk with sales associate and I was sent my 3rd set of brakes, promising they we’re definitely the right ones, well I received them and opened the box only to find hydraulic brakes, NOT electric brakes like I needed, I then returned these and finally went to my local RV dealer and got the right ones, I’ll never go to e trailer again for anything, your customer service is the worst, try hiring employees with knowledge of what they are selling !



by:

So far everything is great ...



by:

The brakes were identical to ones I had and were of high quality. Very easy and quick to install. Etrailer shipping was fast.



by:

Both brake pads were cracked upon arrival. Had a trip to lake Powell with the boat trailer so did not have time to return them and they did still function. Not sure if it was poor quality control or just poor packaging as the packaging was destroyed upon arrival. I can’t believe all the parts were still in there to be honest. Undecided if I would order again from etrailer.



by:

Brakes were as described, matched up with what I ordered and seem to work great.



by:

Great replacements for the (almost) 30 year old Dico assemblies with worn out brake cylinders and bearing grease contaminated shoes. Worked well with the old Dico drums too. The reversing feature works great too.



by:

The ordering and shipping process went just fine, however, when I received my package and opened the box I was surprised to see that there was NO material of any kind separating the two wheel assemblies. They were placed one on top of the other and sent to Washington State all the way from Missouri. Needless to say, the part that was on the bottom is all scratched up, and will more than likely rust the entire back side of the assembly. Not cool..... all it would have taken is a flexable piece of foam.



by:

Item was just as described. Good fit and finish. The corner of one brand new brake shoe was already chipped and loose, wasn’t tickled about that. And the bleeder screws were different on the left and right sides... not a huge deal but still.... attention to detail people. I now have one bleeder screw that takes a 3/8” wrench and another that needs a 10 mm. Again, not a big deal but that’s what reviews are for, the good, the bad and the ugly. I would purchase this product again. Delivery was FAST and FREE!



by:

As always exceptional parts at a great price. Customer service is always excellent, and usually receive items before promised ship date. Not only can I find all my trailer needs but I can find a lot of great accessories for my truck as well. I have ordered Multiple times and always feel good about my purchases and the parts that I receive



by:

Well made quality brake replacements. Very good parts for the price. Brakes were an exact fit replacement for my 2004 EzLoader trailer.



by:

Great company. Brakes w/ backing plates. Everything fit perfectly. Ship on time. Price was better than brick an mortar. I will definitely keep using Etrailer great place.



by:

I was very impressed and appreciative with the help I received from Greg. He was spot on with his advice. To my surprise the parts were delivered the very next day and they were perfect. The parts were the quality I was expecting and installation was easy. Thanks for your helpL



by:

I ordered the parts on-line due to the long wait times on the phone. But when I did get through, Halley was very helpful in getting me the information I needed to make my purchase. The speed and communication of shipping the parts to me was excellent! I will always use etrailer for all my trailer part needs......



by:

Another great update to my 1991 Mastercraft Trailer.



by:

Great Product!



by:

The fit and assembly was perfect with no hassle.
Faster and easier then trying to rebuild the original.
Total assembly time and full bleed about 1.5 hours.



by:

Received my order much faster than I expected. Perfect fit, actually works much better than the OEM brakes I had on my dolly. Five stars for service and product

These are great. Saved a lot of time being all assembled, just bolted them on. Used for a year now. Installed on heavy boat trailer. Work great. reassuring as I have to tow up and down some fairly large hills on the way to the lake.



by:

installed and working fine



by:

Arrived on time and installed easily. Have not yet tested them.



by:

Works as it should.



by:

Product came just as described. Shipping was incredibly quick on such a large item. Ordered Monday evening and Received Thursday.

Great service!



by:

Everything’ came in good shape and was delivered quicker than it was scheduled. Order was complete and packed well. Great service and will use again. Thx

See what our Experts say about this Dexter Trailer Brakes

  • Will theTitan Hydraulic Brake Kit T4423500-400 Work With a 7,000 lb Actuator
    Yes, the Brake Actuator part # T43397007K will be sufficient to power two sets of the Titan Hydraulic Brake Kit part # T4423500-400. The combined weight capacity of the braking assemblies can exceed that of the coupler.

  • Can Free-Backing Plates be Used with Actuator that Has Reverse Lock Out
    Free backing plates would be redundant if the actuator of your trailer already has a reverse lockout but prevents the brakes from applying when backing up but they wouldn't hurt anything otherwise. So if you wanted to use the part # T4423500-400 there's no reason you couldn't.

  • Recommended Replacement Brake Assemblies For Eagle Trailer Drum Brakes
    We have a few product options to replace your brake assemblies. I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 10" - Left/Right Hand - 3,500 lbs # AKFBBRK-35-D. This will give you both assemblies for one axle. These are free-backing so you can back up with your trailer without engaging the trailer brakes. They are marine-grade and designed for boat trailers. The dacromet coating offers corrosion resistance. Another really nice option is the similar brake...

  • Free-Backing Hydraulic Brake Assemblies for Trailer with 3500 lb Axles
    Hey Tim, thanks for the picture of your current brake assemblies. While what you have doesn't look exactly like a free-backing setup you definitely can replace what you have with them. For that I would go with the etrailer part # AKFBBRK-35 which is for 3500 lb axles like what you have and is free-backing. The kit you mentioned is for 3,700 lb axles.

  • Will 4 Bolt Mounting Spacing on Titan Hydraulic Brake Kit Match 2-3/4 Spacing for Backing Plate
    The 4-bolt hole mounting pattern for the Titan Hydraulic Brake Kit # T4423500-400 that you referenced will match up with your bolt spacing. For your hydraulic braking system this is an excellent option especially if you have a surge brake actuator. The free-backing feature allows you to back your trailer up without activating the brakes and the Galphorite plating provides superior corrosion protection. You just need an adjustment spoon like part # W80630 to properly adjust your brakes.

  • Replacement Parts for EZ Loader Trailer with DICO Model 10 Actuator & Reliable Sure Lube Hubs
    For your EZ Loader Trailer with DICO model 10 actuator and Reliable Sure Lube Hubs, I absolutely have recommendations for you. The Titan Zinc-Plated Brake Actuator # T2477600 is the Titan model 10 actuator that is nearly identical to the DICO model 10 you are replacing. If you want the electric lockout, you can use # T4748800 and Shield # T4836100183. For your brake assemblies, I recommend the Titan Hydraulic Brake Kit - Free Backing - Galphorite # T4423500-400 and mounting bolts # BRKH10A....

  • Replacement Titan Brake Shoes For 10" Free Backing Hydraulic Brakes
    We do carry reaplcement brake shoes for the Titan 10" free backing brakes with part # T4744800 and part # T4742700 for uni-servo 10" Titan hydraulic brakes (standard brakes). We do not carry them as a kit for all 4 wheels however, it may be more cost effective to just replace the whole braking assembly instead of the brake shoe. If you have free backing brakes on the trailer I recommend Titan Hydraulic Brake Kit - Free Backing - Galphorite part # T4423500-400 which have a galphorite plating...

  • How To Add 10 Inch Surge Brakes To a 2,500 Lb Trailer Axle On a Boat Trailer
    Yes, the Brake Actuator part # T43397007K will be sufficient to power two sets of the Titan Hydraulic Brake Kit part # T4423500-400 and the Dexter Trailer Hub and Drum Assembly part # 8-247-50UC3 will work with these as well as the spindles on your trailer if what you provided is correct. The weight capacity for the actuator is for the coupler portion, not the master cylinder so you could use braking assemblies that exceed this without issue.

  • Does the Titan T4423500-400 Brake Kit Include Drums?
    The Titan Hydraulic Brake Kit - Free Backing - Galphorite - 10" - Left/Right Hand - 3,750 lbs # T4423500-400 will just be the brakes. If you are needing to replace your drums as well, etrailer.com Easy Grease Trailer Hub/Drum Assembly for 3.5K Axles - 10" Diameter - Galvanized # AKHD-545-35-G-EZ-K will mate to the # T4423500-400 without issues. It should be noted that the # AKHD-545-35-G-EZ-K will use an inner bearing # L68149, outer bearing # L44649, and will have a 5 on 4-1/2 bolt pattern,...

  • What is Most Common 10 inch Diameter Trailer Brake Assembly Capacity
    In the 10 inch brake size the most popular axle capacity is 3,500 lb. I'd be surprised if you had a higher or lower capacity than that but typically you can find the axle capacity either listed on the VIN plate of the trailer or even on the axle itself. A slightly higher capacity at 3,750 lbs for the assemblies wouldn't make a noticeable difference though so the part # T4423500-400 would work.

  • Determining Which Brakes Fit 10" x 2-1/2" Drums On Boat Trailer
    Based on the information you provided either the Titan Hydraulic Brake Kit - Free Backing - 10" - Left and Right Hand Assemblies - 3,750 lbs # T4071600-500 or # T4423500-400 will fit your drums. The only difference between these two brakes is the # T4071600-500 are made of standard metal where the # T4423500-400 have a Galphorite coating giving it superior corrosion resistance. Since you are putting these brakes on a boat trailer I recommend the # T4423500-400 as they will be less likely...

  • Hydraulic 10 Inch Free Backing Trailer Brakes Lock Up When Wet
    What it sounds like is happening with the Dexter Hydraulic Brake Kit - Free Backing - Galphorite - 10" - Left/Right Hand - 3,750 lbs # T4423500-400 locking up when wet is the shoe has likely absorbed moisture and expanded, causing the lock up. That's why when they dry they still work as intended. That's the best guess anyway as I'm not quite sure what else it could be, and unfortunately there isn't a fix for this, so you can either replace the whole brake kit with # T4423500-400 or try...

  • Replacement Brake Shoes And Wheel Cylinders For Mastercraft Boat Trailer
    For your Mastercraft Boat Trailer, I recommend the Titan Hydraulic Brake Kit - Free Backing - Galphorite - 10" - Left/Right Hand - 3,750 lbs # T4423500-400. The complete assembly is often less expensive than replacing the individual components. If you want just the components you mentioned, I recommend the 10" X 2-1/4" Hydraulic Brake Shoe/Lining (One Wheel) # BP04-120 and the Wheel Cylinder - 10" and 12" Single Servo RH # BP17-020 in addition to the left hand # BP17-030.

    The Titan 10" Hydraulic Brake Kit - Free Backing part # T4423500-400 does not come with the installation hardware but we do have exactly what you will need with the Mounting Bolts and Hardware for 10" Single Brake Assembly part # BRKH10AS.
