A seeping rear wheel cylinder soaks the shoes, pulls the car to one side under braking and leaves you with a pedal that never feels right. This ATE rear wheel cylinder, part 644 352 513 01, is the replacement for Porsche 356A and 356B rear drum brakes. Do both sides at the same time so the rear brakes stay balanced.
