Video Transcript for Dexter 7" x 1-3/4" Right Hand Hydraulic Trailer Brakes Review

Today were going to take a look at the Dexter 7 inch hydraulic brake assembly part number 23-399. This assembly is a hydraulic brake assembly with a single servo meaning it has one piston that comes out of our wheel cylinder, pressing the shoe linings out against our drum surface. Couple this right hand side with the left hand side and its got a 2500 pound braking capacity. The reason we know this is the right hand side is because the leading shoe will always be smaller than the trailing shoe. The reason we know this is a 7 inch brake setup is you can measure across the shoe linings and see that its 7 inches.We measure the width of the shoe linings, well see its 1 and , so we have a 7 inch by 1 and inch setup. The installation is setup on a 4 bolt flange, you can see the heads of the stud go through the backing plate and come out the back, those mount to your flange on your axle.

When you initially setup, youll need to make a manual adjustment with the star wheel so that your shoe linings come out against the drum. Youll also need to maintain this which can be done through the access hole in the backing plate. As the shoe linings wear down, youll want to adjust the star wheel adjuster out so that you dont have to take up so much clearance when you hit the brakes. This will need to be done as general maintenance. And there you have it for our 7 inch Dexter hydraulic brake assembly for the right hand side, part number 23-399..

  • 7 x 1-3/4 Hydraulic Brake Assembly Replacement
  • You can replace the Atwood hydraulic brake assembly with the Dexter hydraulic brake assembly as long as the mounting bolt pattern on the assembly matches. I went to the warehouse and measured the Right and left Dexter, 23-399 and 23-398, Hydraulic Brake Assemblies and they have a 2-7/8 inch on center four bolt pattern.

  • Can Dexter Hydraulic Drum Brakes be Used in Place of Atwood 7 x 1-3/4 Inch Brakes
  • There should be no problem going with Dexter hydraulic drum brakes # 23-399 and # 23-398 in place of the Atwood brakes. You just have to make sure that you have the correct mounting pattern for the Dexter brakes. The Dexter brakes mount on a 4 bolt flange. The holes are 2-7/8 inches apart on center. The center hole is 1.64 inches in diameter. If this matches your flange then you can use the Dexter brakes.
