Replace old brakes

Good replacement for old trailer brakes. Everything fit well and customer service was really knowledgeable about the job I was doing. Would recommend this company to anyone doing work on a Pacific Trailer. Shipping was a little expensive, but that’s not the companies fault. It’s the cost of doing business when shipping 400 miles away with heavy products.

nice conversion kit

I converted my drum brakes to disc brakes with this kit. Everything I needed was provided, it made it an easy project.

Surge Brake kit

Excellent kit, replaced a 15 year old disk brake set. Easy to install.
The brake actuator was a better design it also has the protected brake fluid reservoir.

A 60 conversion Kit

I found this kit to be a straight forward install, without any difficulties. I would have rated it a 5-star but the kit was missing the mounting bolts for the calipers and a T-fitting for the brake lines. I had to buy new bolts and use the old T- fitting from the axle I took off of my boat trailer. Of course the old T-fitting was welded to the old axle!

Overall very happy with the product and service from Pacific Boat Trailers.

These items where for a routine repair

This is a well designed kit that fit my needs perfectly.

The only reason I gave it 4 stars versus 5 is that parts were missing from my original order (Bearing Buddies), and I had to call and have them shipped seperately. They took care of the issue, and I appreciated it.
