    Rated 5 out of 5 by from Power Brake Booster & Master Cylinder Kit This is a really beautiful kit. The fit and finish is superior. This is a great product and a great price too.

    Rated 5 out of 5 by from A Perfect Piece The OE Power Brake Booster and Master Cylinder was an eyesore. The booster's paint was chipped and the master cylinder was badly rusted. The new pieces are beautifully plated and polished.

    Rated 2 out of 5 by from Finally got through this total build (i.e. Stainless lines and full OEM front/rear parts). 1. Good price but some parts from 2 kits were needed to accomplish the project. Adjustments were made by the JEGS sales associate. 2. After bleeding 2x with a squishy pedal.... Asked some of my Salty Sea Bee Construction Mechanics to see what was missing... The internal push rod, between the master cylinder and the power booster needs more length (i.e. the peddle is to soft and can hardly stop the truck). Additional effort via a slew of You Tube Videos and original 71 C20 Tech pub and knowledge of a vernier calliper and depth helped me dial this in "better." Unnecessary elements to what should have been factory specs. 2. The fluid chambers are smaller than OEM units and require a constant eye on bleeding the lines.

    Rated 2 out of 5 by from Looks very nice but........quality is poor This MC / Booster combo looks beautiful but the seal / o-ring where the MC mates up to the booster is weeping brake fluid which means it is not getting a good seal. Last thing I need is my brakes going out down the road. I am annoyed that I have to now pay to have this uninstalled and pay out of my own pocket to have it returned. This is a quality control issue and should have been addressed as such my customer service when I called it in.

    71 Chevy C20 350 CU with Edlebrock performer manifold and 1406 carb. It had vacuum issues and I'm hoping this will help and still offer class IV towing capabilities for braking.

    Asked by: Salty Seabee
    Yes, this should work in your Chevy truck as long as you still have disc brakes in the front and drum brakes in the rear.

    I am assuming the electrical post on the proportioning valve is the brake light switch, right?

    Asked by: The1ma
    Yes, it is used in some applications.
