Each master cylinder comes ready to install with all new parts including castings, pistons, returns springs and other components. New pistons and return springs are vital to the performance of a car’s brake system, helping to prevent brake drag. Brake drag can cause the caliper and rotor to overheat, which will wear down your brake pads and rotor prematurely. The master cylinder’s body and plastic reservoir (where included) match center to center for proper fit and leak-free operation. EPDM and SBR rubber components offer superior resistance to heat, corrosion and leakage.

Very disappointed. Never had problems with this product before. Put it in immediately. It didn't work. Had to take it out. Put another one in that one. Worked
