## Customer Reviews

### ⭐⭐⭐⭐⭐ trailer brakes
*by A***R on April 19, 2025*

fit my 1996 poonton trailer perfectly Thanks

### ⭐⭐⭐⭐⭐ perfect fit
*by P***F on December 11, 2024*

easy install to replace the surge brakes on my boat trailer. 4 bolts and you're done! I replaced the brake lines , and actuator, also. With everything new, it bled easily, adjusted perfectly all by itself, and they work great. I don't have to do anything to back up, either.

### ⭐⭐⭐⭐⭐ Great replacement for my 1993 trailmaster boat trailer
*by G***S on July 23, 2020*

These seem to be better quality than the OEM brakes that were replaced as everything appears to be stainless steel. The OEM had several non-stainless components that were severely corroded. I was just going to replace the shoes, but I'm glad I got the whole assembly. Hint: If you're like me and haven't done any work on drum brakes in years, (like 25 years) take a few minutes to reacquaint yourself with the process. At first I though they didn't fit because I had installed the brake line before putting the drum back on. I pushed in the brake cylinder, thinking it was fully compressed, like I would with a disk caliper but gravity was causing the brake fluid to fill cylinder just enough that by the time I picked up the drum it wouldn't go back on. Ha! took me a WHILE to figure out what was going on. Install the drum first - then the brake line. Hopefully that saves someone else a few headaches.
