Video Transcript for Dexter Axle Trailer Brakes 23-403 Review

Today we're going to take a look at the Dexter 12 1/4 inch Duo Servo right hand hydraulic drum brake assembly for 9,000 pound axles. This hydraulic drum brake assembly is designed for use with surge type trailer brake actuators. It is the dual plunger design so it will deliver the same amount of braking when driving either forward or in reverse. Also has the forward self-adjust feature here. Basically you can tell that by the cable that goes around the pole and attaches to the lever. What that does is when you're going forward it will self-adjust your brakes. This is a right hand passenger side assembly.

The way you can tell that, now on a new one it will always have a sticker that will tell you that. If you wanted to find out if there wasn't a sticker on there, the easiest way is to look at the length of the pads. On this one it goes from here to here. If we look at this shoe the pad's all the way here to here. This is a longer pad.

This is a shorter pad. The shorter pad is the primary shoe, it will always face the front of the trailer. That will tell you that this will go this way, which will mean it's on the right hand passenger side. The size on this is a 12 1/4 by 3 3/8. When they do the size the measurement they're giving you the 12 1/4 would be here to here. If we put a ruler on it edge to edge, right at 12 1/4.

The 3 3/8 inch would be the width of the pad. If we put a ruler on that, there's your 3 3/8 inches. This does use a mounting flange of a four hole or a four bolt mounting flange. The mounting bolts attaches to your brake mounting flange. We do sell those separately on our website. Again, this brake assembly is designed for axles rated up to 9,000 pounds. That should do it for the review on the Dexter 12 1/4 inch Duo Servo right hand hydraulic drum brake assembly for 9,000 pound axles..
