Upgrade your manual brake car to a 9 in. slimline power booster and a 1 in. dual bore master cylinder with our quick install kit. This kit allows you to upgrade your factory single bowl manual brake car to dual bowl power brakes in no time. In this kit you receive the brake lines necessary to route from the new master cylinder to your factory distribution block. Additionally we include an adjustable valve which will be installed to your rear brake line with the hardware supplied. This adjustable valve allows you to fine tune the amount of pressure your rear brakes receive in order to prevent rear wheel lockup. With this kit you will also receive a factory style power brake pedal that installs easily into the factory pedal support with no modifications. A great kit with a factory look and easy installation!
