Overall Assessment

Customers appreciate the product's great fit, good quality, and easy installation. Many highlight the power brakes as being reliable, easy to use, and a major upgrade. The booster and bracket's finishing, as well as their durability and practicality, received positive remarks. However, some mentioned the master cylinder as substandard and suggested a paint application to prevent rust. They complimented the instructions provided via the company website but suggested an addition of reverse threads for convenient rod adjustment. Despite minor setbacks, the product is highly recommended for its performance and quality.

I was able to replace the 1970 Chevy C-50 old Brake Hydro boost under the drivers side seat with this. I had to do a little modifications but it bolted up and replaced the old single master cylinder.

The brackets and rods are nice quality. The booster seem to be good. The master cylinder was garbage. It would not bench bleed at all. Got a part store master cylinder and it works fine. Did not want the hassle of dealing with returning it or shipping it.
