Send firm hydraulic pressure to your rear drum brakes with the Dorman First Stop Drum Brake Wheel Cylinder W370038. Mounted at the rear, it converts brake-line fluid pressure into the mechanical push that forces the brake shoes outward against the drum. It drops in as a direct-fit replacement for the 1996-2000 Toyota RAV4 [All], 2003-2008 Pontiac Vibe [All], and 2003-2008 Toyota Matrix [All], and is built to match the original wheel cylinder's fit, function, and performance on those vehicles.
- Cast iron body: with a 0.688 in inside diameter bore and an M10 x 1.0 inlet thread.
- EPDM rubber cups and boots: for long-lasting sealing performance.
- Surface-tested bore: checked to provide an optimum sealing surface for the pressure cups.
- Bleeder screw included: (bleeder screw cap not included).
Replacing the wheel cylinder while servicing drum brakes is a quick, sure way to keep the brake system working properly. Signs this part may need replacing include brake fluid leaking behind the drum, damp shoes, or a low or spongy pedal — diagnose the cause before ordering. The listed applications use two rear wheel cylinders; sold individually, this listing is for one, so order two and replace both sides together as a matched set for even braking. Country of origin: China.
Manufacturer part number W370038.
