Product Details

PowerStop’s Autospecialty OE Replacement Brake Calipers are built for stock-style service on rear brake systems that need a direct-fit replacement. The L5306 uses a floating caliper layout with a cast iron body and phenolic pistons, along with new internal and external service components to support consistent piston movement and sealing. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Needs

• Rear brake drag caused by sticking caliper movement
• Brake fluid leakage from worn seals or bleeder hardware
• Uneven rear pad wear on Silverado 2500 HD and Sierra 2500 HD trucks
• Reduced braking response from a worn rear right caliper
• Corrosion-related caliper seizure on heavy-duty truck brake systems

Installation Notes and Tips

Verify rear right fitment before ordering, especially on Silverado 3500 HD and Sierra 3500 HD models with SRW disc brake rotors. Inspect brake pads, rotor condition, and brake fluid during installation, and bleed the hydraulic system after caliper replacement. Confirm bleeder screw thread size and bracket alignment before final assembly. PowerStop L5306 should be matched to the exact vehicle year, make, model, and rear right position listed above.

Quality Assurance

Each caliper is pressure tested to verify piston operation and check for leaks before release. PowerStop remanufactures the caliper and bracket assembly in its Chicago, IL facility and uses new seals, dust boots, bleeder screws, and stainless steel pad abutment clips during assembly for consistent OE-style service quality.
