Power Brake Booster Conversion Kit

These heavy duty power brake conversion kits convert a single diaphragm booster to a dual diaphragm setup which creates more stopping power with less pedal pressure. Heavy Duty Dual Diaphragm Brake Booster and 1″ Bore Master Cylinder. May require modifications for brake lines at the master cylinder and slight adjustment of the push rod at the front of the booster. May require converting the brake light switch to an older CJ style (Part # J5352620), or the installing of an inline hydraulic brake light switch. If running 4-wheel disc brakes, we recommend eliminating or modifying stock brake proportioning valve to get adequate pressure to the rear brakes.
