A wheel cylinder may need replacing if you see brake fluid seeping at the drum or backing plate, feel a soft or low pedal, or notice the vehicle pulling while braking. Other brake parts can cause these signs, so diagnose the cause before replacing. The listed applications use two wheel cylinders. This listing is for one, and replacing both sides together is recommended for balanced braking. The package contains one drum brake wheel cylinder. Country of origin: China.
