- Quality materials: built with high-quality EPDM rubber cups and boots.
- Professionally tested: the cylinder bores are surface-tested for an optimum sealing surface for the pressure cups.
Signs a wheel cylinder may need replacing include brake fluid seeping inside the drum or onto the backing plate, a soft or sinking brake pedal, a dropping fluid level, or uneven braking. Diagnose the cause before replacing parts. This unit is cataloged for the rear position on both the left and right sides. Replacing both rear wheel cylinders together is recommended for balanced braking, and the brake system should be bled after installation.
