Our old, wasted power brake booster and master cylinder made room for Dave’s Customs Unlimited’s CJ/YJ power brake conversion kit. This setup is unique as it is a dual diaphragm brake booster and a high performance master cylinder with various bore diameters for applications such as disc brakes front and rear, or aftermarket axles with larger brakes, or for upgrading to power brakes. The dual diaphragm design creates more stopping power with less pedal pressure. This is a high quality kit. The bracket, booster, and master cylinder lid are all zinc plated. The push rod is adjustable, unlike the factory rod, so pedal height can be adjusted.
