Centric Parts Drum Brake Wheel Cylinder P/N:134.66029

Keep hydraulic pressure flowing to your rear brake shoes with the Centric Parts drum brake wheel cylinder (P/N 134.66029, also written 13466029). It installs as a direct-fit replacement for the 2005-2008 Chevrolet Silverado 1500, the 2007 Chevrolet Silverado 1500 Classic, the 2005-2008 GMC Sierra 1500, and the 2007 GMC Sierra 1500 Classic (All engines). Mounted in the rear drum brake, this wheel cylinder receives hydraulic pressure from the master cylinder and pushes the brake shoes outward against the drum to apply the rear brakes.

• Rear drum application: replaces the original rear wheel cylinder on the listed trucks.
• Hydraulic actuation: converts brake-line pressure into the outward motion that presses the shoes against the drum.
• Per-application quantity: the listed applications use two, one per rear wheel — plan to replace both sides together for balanced braking.
• Signs it may need replacing: brake fluid seeping at the backing plate, a soft or sinking pedal, or fluid-contaminated shoes can point to a leaking wheel cylinder; diagnose the cause before replacing.

If a leaking or seized rear wheel cylinder is behind your braking issue, this Centric Parts unit replaces that failed hydraulic component. See the Buyer's Guide tab to confirm the fit for your vehicle.
