Quality part and quick shipping

I was experiencing a occasional disc brake drag on my marine master boat trailer, I replaced the calipers two years (Pacific Trailer) ago and thought I had the problem fixed. Took old master clinder off and found a lot of rust and debri causing the piston to stick. Should have replaced it when doing the calipers(do it right the first time!). This was a cheap repair compared to replacing the complete A60 assembly, but let me say it's a pain in the ass to get it all lined up and reinstalled. If you time and patience is valuable, buy the assembly!

Plug and play replacement

Complete trailer rebuild. New axles, leaf springs, equalizers, hubs and brakes. I had trouble bleeding brakes. I wasn't able to pump fluid through the system. This new UPF A-60 was the ticket. Simple install and voila, Ive got brakes

Adam C. (Findlay, US)
Just what I needed

Not sure if mine was completely bad as I found later that I had a plugged and damaged line. Either way this is just what I needed to replace the old one. Quick ship and great company to deal with.
