Overall Assessment

Customers praise the product for its excellent performance, particularly the power brakes kit for older cars like the '55 Chevy. Its usability is specifically noted, with highly informative instructions aiding in smooth installation, although some users found them complex at first. One minor issue was found regarding the sizing of some parts, however, this didn't obstruct the overall assembly process. Despite this, the product's outstanding quality and enhanced safety features make it a recommended purchase over competitors.

I bought the power brakes kit for my 55 Chevy and I couldn't be happier. My brakes are excellent.

Read the the instructions, then reread them. They are very helpful -after the 3rd reading I finally saw the note to connect wire from proportioning valve to dash light. Only issue I had was a hole in each caliper mounts was smaller than the threaded bolt that had to go through it. Assigned my 88 yr father the task of grinding them larger with a Dremel tool. Also thanks for the heads up about needing 15" wheel to fit where 14" would've not cleared caliper.
