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.

Hydraulic drum brake assemblies provide superior protection from corrosion and let you reverse without actuating. Designed for use with hydraulic brake actuators that don't include reverse lockouts. Fit most 10", 12" or 13" wheels.


My one gripe with this set of brakes is that the bleeder valve is a bit short and small, and that makes it difficult to access the bleeder between the two bolts that hold the wheel cylinders in place. Other than that, they were a direct replacement and while they don't accept a banjo fitting like the originals, I was able to flare out a set of brake lines and made 'em work.
I think they're a good value.


Wheel cylinder was seized and grease seal had leaked,soaking the shoes and everything else. Four nuts and a break line to remove made replacement easy. Replaced seal too. Picture of before and a couple after.


Great customer service. Product was point on. Price very competitive. Highly recommend


Thank you for the great service I will be ordering again my next paycheck


I purchased this Titan Hydraulic Brake Kit from for my '08 Tennessee Trailer and am very happy with the entire process. Ordering was simple, completing the sale was easy. I received the product in a relatively short time.
These are identical replacement brakes for my trailer, which I have been having a hard time finding. Simply remove the old brake plate and install the new. Very simple, and made with high quality parts, such as stainless steel springs. I believe these brakes will last for a long time. I am completely satisfied.


Excellent replacement for brake plate assembly. Unusual sizing parts I could not find locally and pricing is excellent . Customer service is excellent you can easily speak with someone on the phone about your parts or shipping. I had a problem with one of the components and notified them they immediately sent a replacement no questions asked. I highly recommend for trailer parts.


Very nicely engineered, because there are two brake adjusters on each side I used a sharpie and marked the back side with arrows for the correct direction to expand them, nice to have brakes that unlock in reverse automatically


Parts received as ordered great to do business with very nogiable of products very satisfied


SERVICE WAS EXCELLENT. I ordered the wrong parts, no problem returning the parts for a refund. The staff made it easy. I should be getting correct parts today.


Great Product and Excellent website



Great parts and great customer service.

  • Replacement 8 Inch Hydraulic Brake Assembly for the Reliable Brand
    The Titan Hydraulic Brake Kit part # T4442100-000 require a bolt pattern of 4 on 4" and are designed as a replacement for 8.5" brakes that are 2.5" wide. I am unable to find exact specifications on the assembly you have but check these measurements and confirm they are the same. If they are you're good to go.

  • Replacement 8-1/2" X 2-1/4" Brake Assemblies For a Road King Boat Trailer With Titan Brakes
    We currently carry the Dexter Hydraulic Brake Kit # T4442100-000 which replaced the Titan 8-1/2" X 2-1/4" hydraulic brakes. You will need to replace your brake assemblies as the parts for the Titan, including the wheel cylinders are no longer in production.

  • How Do Titan Hydraulic Drum Brakes Adjust
    Basically you want to tighten downt the star wheels of the Titan Hydraulic Brake Kit # T4442100-000 till there is a light drag as you turn the wheel. If you pull out the plugs on the back of the assemblies you'll be able to access the star wheel where you'll want to apply even adjustments to both pads as you get to the correct drag. The part # W80630 is a tool designed to make this an easier job.

  • How Do You Adjust Hydraulic Drum Trailer Brakes
    The 8-1/2 inch hydraulic brakes that fit drum # T1662200042, such as set # T4442100-000, have adjustment holes on the backs of the assemblies, see picture. You would use a brake adjustment tool, # W80630, to rotate the star wheels on the other sides of the holes to make the brakes more or less aggressive.

  • Is The Dexter DX7.5L A-60 Brake Actuator # DX33FR Overkill for a 5,000LB Boat Trailer?
    The Dexter DX7.5L A-60 Brake Actuator # DX33FR is a good choice to work with the Dexter Hydraulic Brake Kit # T4442100-000. The weight rating being slightly higher than your trailer weight with your boat is okay and not overkill. This particular actuator fits a 2" ball and has a zinc coating with an aluminum master cylinder. This will greatly reduce corrosion to the master cylinder since it will be used around water frequently.

  • How To Use Trailer Valet Trailer Dolly TVRVR9 With Boat Trailer With Surge Brake Actuator
    You are correct. Since your boat trailer has an electric lockout solenoid you will not be able to use the Trailer Valet RVR9 Remote-Controlled Trailer Dolly - Wireless Remote - 9,000 lbs # TVRVR9 without the brakes being applied. Instead what you can do is replace your current brakes with free backing brakes which will make it where you do not need the reverse lockout solenoid. To do this you will need to know what size brakes are on your boat trailer. If you have 8-1/2" brakes we have...

  • Will The Dexter 8-1/2" Drum Brakes Fit a Tandem Axle Load-Rite Boat Trailer?
    The Dexter Hydraulic Brake Kit # T4442100-000 will fit your trailer provided you do have a mounting bolt flange with mounting holes 4" by 4" on center in a square pattern. If you have a different mounting pattern for the brake assemblies please let me know so I can find you the correct size brakes. These will need to have a 8-1/2" drum hub like the # T1544500042. This hub fits on a spindle with the Inner bearing # L68149 (Inner diameter 1-3/8"), Outer bearing # L44649 (Inner diameter 1-1/16"),...

  • Replacement Hydraulic Surge Brakes for a 1994 Eagle Trailer
    I can help you determine the correct size for replacement brakes but we don't have a database of parts for specific trailers. With bearings # L68149 and # L44649 this narrows it down a lot. If do indeed have a 3,500 pound then you'll need 10 inch brakes like the Dacromet Assemblies # AKUBRK-35-D. These are great for boat trailers because of their resistance to corrosion. The kit includes both left and right hand side brakes that are labeled to make the install easier. Also the bolts...

    Thank you for the pictures! We do offer a trailer brake option that will work with the 10" wheels on your 2014 Shorelander Trailer.
