  • Free Backing Hydraulic Drum Brakes
    I have a solution for you but no, the Dexter Hydraulic Drum Brakes item # 23-336-337 would lock up every time you backed your trailer up. You need free backing brakes like the Dexter Hydraulic Trailer Brake Kit - Free Backing - 12" - Left and Right Hand Assemblies item # 23-342-343. These drum brakes are rated up to 7,000 lbs like the ones you were looking at.

  • Replacement Brake Shoes or Assemblies for 1999 Manning Triaxle Trailer
    The Dexter Hydraulic Drum Brake Assembly - Duo Servo - 12" - Left Hand - 7,000 lbs # 23-336 is the Left Hand Assembly, but if you just want the brake shoes use 12" x 2" Hydraulic Trailer Brake Shoe and Lining (One Wheel) # BP04-160. If you want to replace both assemblies on an axle use Dexter Hydraulic Drum Brake Kit - Duo Servo - 12" - Left and Right Hand Assemblies - 7,000 lbs # 23-336-337.

  • Replacement Dexter Brake Assembly Set for 7k Hydraulic Drum Axle
    The part number you referenced is for a Dexter single servo 7k drum brake assembly that is 12 inch in diameter. We have the duo servo kit part # 23-336-337 which will be exactly what you want. It comes with a left and right assembly as well. Only difference is the duo servo setup which means both brake pads pressurize against the drum when you apply the brakes.

  • Comparing the Dexter Duo-Servo Brake Kit with the etrailer Uni-Servo Brake Kit
    The Dexter Hydraulic Drum Brake Kit # 23-336-337 that you mentioned are Duo-Servo brakes meaning they deliver the same amount of braking whether you are driving either forward or in reverse. The Hydraulic Trailer Brake Kit # AKUBRK-7 that you referenced are Uni-Servo brakes which means that they will still apply braking when going in reverse, just not as much (about 20% total power) as the Duo-Servo brakes. Unless you plan on doing a lot of backing up with your trailer and you need that...

  • Recommended Electric Over Hydraulic System for Keystone Montana High Country 5th Wheel Trailer
    As long as your truck's controller has the electric over hydraulic actuator compatibility you won't need to change anything in your truck. If it doesn't there are many options that you can use as a replacement. I recommend the Prodigy P3 # 90195 if you need a replacement. For your Montana High Country 5th wheel trailer, the HydraStar Electric Over Hydraulic Actuator Kit for Drum Brakes - 1,000 psi # HBA-10-252-82 is my recommendation for you. This will give you what you need to your...

  • Does Car Trailer with 7k Axles Need Free-Backing Brake Assemblies as Replacements
    If your car trailer has a reverse lock out solenoid on it then you wouldn't need free-backing plates and the part # 23-336-337 would be the set you'd need for each axle. If you do not have a reverse lockout solenoid on your actuator (two wires ran to the back of it) you'd need free-backing plates like the part # 23-342-343 so that you could back the trailer up without the brakes applying.

  • Can 12 inch Electric Trailer Brake Assemblies be Replaced with Hydraulic Assemblies
    Yes, if you had a set of 12 by 2 inch electric trailer drum brakes you could replace them with the hydraulic drum brake kit part # 23-336-337 or vice versa. The Dexter electric set in the same size and 7k capacity is the part # 23-464-465.

  • Hydraulic Trailer Brake Assemblies Compatible with the Dexter 8-174-5UC3 Hub Drum Assemblies
    The Dexter Trailer Hub and Drum Assembly - 6,000-lb and 7,000-lb Axles - 12" - 5 Spoke Utility # 8-174-5UC3 is compatible with either the Dexter Hydraulic Drum Brake Kit - Duo Servo - 12" - Left and Right Hand Assemblies - 7,000 lbs # 23-336-337 or the free backing Uno Servo # 23-342-343. The Duo Servo option will give you the best braking capacity with those hubs so that is my recommendation.

  • PSI Rating for Dexter Hydraulic Trailer Brakes
    Hey Bik; since the Dexter Hydraulic Trailer Brakes # 23-336-337 are under 8k the correct psi is 1,000 lbs. Are you looking for an electric over hydraulic actuator? If so, you can use the Hydrastar Electric Over Hydraulic Actuator for Drum Brakes # HBA-10. If the brakes were rated for an 8k axle or higher you would need a 1,200 psi actuator like the # HBA-12 instead.

  • Converting Electric Brakes to Electric Over Hydraulic on Horse Trailer
    You will experience an increase in braking power if you switch from electric drum to hydraulic drum brakes.

  • How to Tell if Hydrastar Disc Brake Kit Will Fit a 2008 KZ Sportster 40P Toy Hauler
    As long as your current hubs use the following bearings and grease seal, the Hydrastar Disc Brake Kit w/ Actuator # HYD54FR will work for your trailer: - Inner bearing 25580 - Outer bearing 14125A - Grease Seal 2.250" ID and 3.376" OD This also uses 9/16" studs so you'll need to ensure this matches your current setup.
