Video Transcript for Dexter Axle Trailer Brakes - Hydraulic Drum Brakes - 23-312-313 Review

Today we're going to take a look at the Dexter 10" Uni-Servo Hydraulic Trailer Brake Kit. It's a left- and right-hand side assembly for 3500 pound axles. These are hydraulic drum brake assemblies, they're designed for use with surge-type trailer brake actuators. These assemblies are a Uni-Servo which is a single plunger design, and they are manual adjustment brakes so they do require periodic manual adjustment. Right down here is your adjustment gear. Now, it does come with the left-hand driver's side and the right-hand passenger's side brake assembly. The bolts are included to mount it, and the mounting nuts are also included.

And the other nice thing is they include the rubber adjuster plugs right here, and what those do is they cover the access holes here. Those holes are used to adjust your brake gear right here. So when you're done adjusting it you put the plugs back in and it's nice because it will keep any dirt and grime out of your assemblies and off your brake shoes. A few specs on this. The size on these brake assemblies are 10" by 2-1/4", and that measurement, the 10" would be the diameter, which is measured from this shoe to this shoe. So if we put a ruler on that there's your 10" diameter.

And the 2-1/4 would be the width of the pad on the shoe, so there's 2-1/4" wide. And as you can see, this is a four bolt pattern so it does require a brake mounting flange of four bolts. And it does require the use of 10" brake drums. The wheel size used on these is 13", 14" and 15". The axle rating again is 3500 pound axles. And the last thing I just want to mention to you is that when you do receive these brand new they will have a sticker that will say right-hand or left-hand, but just to let you know if the sticker wasn't here the easiest way to tell is just look at the length of the pad on the shoe.

So if you look at this pad it goes from here to here. And on this shoe it goes from here to here. This is the longer pad, this is the shorter pad. The shorter pad is the primary shoe and that always faces the front of the trailer, so that'll tell you that this is for the right-hand passenger side. And if you look at the other one, here's the shorter pad, here's the longer pad, so that's for your left-hand driver's side. But that should do it for the review on the Dexter 10" Uni-Servo Hydraulic Trailer Brake Kit with the left- and right-hand side brake assemblies for 3500 pound axles..

  • Replacement Brakes for Unknown Dexter Axle on 1987 Fleetwood 5th Wheel Trailer

  • Are Dexter Hydraulic Trailer Brakes # 23-312-313 Free Backing
  • The Dexter Hydraulic Trailer Brake Kit # 23-312-313 that you referenced are standard uni-servo assemblies and are not free-backing. These will not automatically disengage when going in reverse with the trailer. For 3,500 pound free-backing assemblies I instead recommend the etrailer.com Hydraulic Trailer Brake Kit # AKFBBRK-35. This kit includes both the left and right hand assemblies and they use automotive-grade friction material that's molded to the shoe. This allows the pads to...
