Video Transcript for Dexter Axle Trailer Brakes 23-402 Review

Today we're going to take a look at the Dexter 12-1/4 left hand driver's side hydraulic drum brake assembly for 9,000 pound axles. Hydraulic drum brake assemblies are designed for use with surge type trailer brake actuators. This one happens to be a dual circle design which is a dual plunger design. This will deliver the same amount of braking when driving either forward or in reverse. These are also a self adjusting brake, and you can tell that by when you see the pulley with the cable that goes around it. It attaches to the lever down here.

That signifies that it's a self adjusting brake. They'll automatically adjust to deliver optimum performance and braking power. There's no need to manually adjust them, and what's nice about that is it will give you proper adjustment which will lead to better brake efficiency and less wear on your tow vehicle brakes. This part includes the left hand driver's side brake assembly. Now, the mounting bolts and hardware to install this is sold separately on our website, and it's usually listed on this product pages an a related product. A few dimensions on this, this is a 12-1/4 inch diameter by 3-3/8 inch wide brake assembly, and what they're measuring the diameter ...

We would measure from this shoe all the way across to this shoe, so if we put a ruler there's your 12-1/4 inch diameter, and then the 3-3/8 would be the width of the brake pad on the shoe, so there's your 3-3/8 inch wide, and if you see there's the four bolt holes, so it uses a brake mounting flange bolt pattern of four holes. It does require the use of 12-1/4 inch brake drums, and the wheel size that will fit on this brake assembly is 15 inches and larger, and again it is designed for axles rated up to 9,000 pounds. The last thing I do want to show you is how to tell that this is the left hand driver's side assembly. Now, on a new assembly of course they'll be a sticker that you'll see that will tell you that, but if that sticker wasn't on there the easiest way to tell is you look at the length of the pad on the brake shoe. This pad goes from here all the way to here. This one's from here to here.

The shorter pad. This is the longer pad. The shorter pad is the primary shoe that faces the front of the trailer, so that's going to tell you this goes on the left hand driver's side of the trailer. That should do it on the review on the Dexter 12-1/4 inch left hand driver's side hydraulic drum brake assembly for 9,000 pound axles.
