Video Transcript for Review of Dexter Axle Trailer Brakes - Right Hand Drum Brake Assembly - 23-403

Hello, everybody, this is Jeff at etrailer.com. Today, we're going to take a look at this Dexter 12 and a quarter inch, right-hand passenger side, self-adjusting, hydraulic drum brake assembly, for 8,000 pound axles.Now, this hydraulic drum brake assembly is designed for use with surge-type trailer brake actuators. This assembly happens to be a dual plunger design. You can see the plunger on each side here. This dual plunger design will deliver the same amount of braking when driving either forward or in reverse.And these also are self-adjusting brakes. And you can tell that by, if you look at the cable that goes around the wheel and it connects to the lever down here, it'll automatically adjust the brakes.

The self-adjusting brakes automatically adjust to deliver optimum performance and braking power. There is no need for any constant manual brake adjustments. Basically, after you initially install this, you do your initial adjustment, and from then on it'll adjust automatically. And of course, proper adjustment leads to better brake efficiency, and less we're on your tow vehicle's brakes.Now the brake shoes themselves, they are lined with an automotive grade friction material. And that friction material is fully bonded and not riveted to the shoes.

Gives you a lot longer life, more braking torque. Now this part will include this one 12 and a quarter inch by three and three eighths inch passenger side, hydraulic drum brake assembly.And when we say passenger side, you might wonder how to tell the difference of what side the assembly goes on. So when you get a new one, of course, there'll be a sticker that'll tell you what side it's for. But if that sticker wasn't there, the easiest way to tell is if you look at the length of the pad on the shoe. This pad goes all the way from here, all the way to here.

And if you look at the other pad, it goes from here to here. So this is the shorter pad. The shorter pad is your primary shoe, and that'll always fit the front of the trailer. So that's going to tell you, it goes on this side, which is the right hand passenger side assembly.Now the mounting hardware is not included. We do sell that separately on our website.

And it's usually listed on this product page as a related product. Just to show you the back of the wheel. You can see the four holes. It is designed to mount to a four bolt, brake mounting flange. This part is made in the USA. Specs on this, the application is for most standard hub and drum assemblies, including Dexter and Lippert. We mentioned it fits 8,000 pound axles.Now the size of this, we said, is a 12 and a quarter inch by three and three eighths inch. And what those measurements mean, the 12 and a quarter inch is the diameter. So it's measured from here to here. So if we put our brake, or our ruler on it, there's your 12 and a quarter inch diameter. And a three and three eighths inch is the measurement of the width of the shoe or the pad. So you measure the width, three and three eighths inches. This assembly does require 12 and a quarter inch diameter brake drums, and it does fit 15 inch and larger wheels. But that should do it for the review on the Dexter 12 and a quarter inch, right-hand passenger side, self-adjusting hydraulic drum brake assembly, for 8,000 pound axles.
