Description

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. Note: Engine vacuum needs to be a minimum of 18 inches of vacuum at idle when the engine is warm for the power brake setup to function properly.
