Video Transcript for Dexter Axle Trailer Brakes 23-410 Review

Today we're going to take a look at the Dexter Duo-Servo left hand hydraulic drum brake assembly for 9,000 pound axles. This is a 12 1/4 inch by three and 3/8 inch driver side hydraulic trailer brake assembly. Features a dual plunger design. The dual plunger design will deliver the same amount of braking when driving either forward or in reverse. This is a hydraulic drum brake assembly. It's designed for use with surge type trailer brake actuators.

This does have the forward self-adjusting brake system. Basically this cable right here that attaches down to this lever so it will self-adjust as you use your brakes. The mounting flange on this, let me just inaudible 00:00:34 over to the back, you can see is a seven bolt mounting flange design. The mounting bolts to install this, we do sell separately. Now the configuration on this, this is a left hand driver side assembly and normally when you get them it'll have a sticker on that'll tell you what side it goes on. If the sticker wasn't on there, just a hint to let you know how to tell what side this goes on, just look at the length of the pad on the shoes.

If you see the pad here, it goes from here to here and if we turn to this one, it goes all the way from here to here. That's a longer pad, so basically when you put a brake on, the shorter pad which is the primary shoe, will always face the front of the trailer, so that'll let you know that this is a left hand driver side. The dimensions on it are 12 1/4 by three and 3/8, we can measure that. The 12 1/4 is all the way across the diameter from the edge of the pad to the other pad. There's your 12 1/4 inches. Then the three and 3/8 would be the width of the pad, so if we put it on there, three and 3/8.

Again, this assembly is rated for axles up to 9.000 pounds. That should do it for the review on the Dexter Duo-Servo left hand hydraulic drum brake assembly for 9,000 pound axles.
