Product Details

This PowerStop Autospecialty OE Replacement Brake Caliper is built for drivers replacing a worn or leaking rear left caliper on a Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, Chevrolet Suburban 3500 HD, GMC Sierra 2500 HD, or GMC Sierra 3500 HD. The L5307 follows stock-style dimensions and hardware layout for direct installation on the listed applications, including Silverado 2500 HD and Sierra 3500 HD models with SRW disc brake rotor notes where specified.

The PowerStop OE Replacement Caliper line focuses on practical brake service: remanufactured caliper and bracket assemblies, pressure testing, new internal sealing components, and corrosion-resistant pad contact hardware. This makes L5307 a straightforward choice for restoring rear brake function without changing the original brake system design.

What It Helps Address

• Brake fluid leaks from a worn rear left caliper
• Uneven rear brake pad wear caused by sticking caliper movement
• Reduced braking response from piston or seal wear
• Noise or drag related to damaged slide components
• Corrosion-related service issues on the rear brake assembly

Installation Notes and Tips

• Verify rear left position before ordering; this part is not for other corners of the vehicle.
• Confirm rotor configuration and application notes, especially on Silverado 3500 HD and Sierra 3500 HD SRW disc brake rotor setups.
• Inspect brake hoses, pads, and rotors during caliper replacement to avoid repeat service.
• Bleed the brake system after installation to remove air and restore pedal feel.

Quality Assurance

PowerStop remanufactures the caliper and bracket assembly in its Chicago, IL facility and pressure tests each unit to verify piston operation and check for leaks. The use of new seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel pad abutment clips supports consistent OE-style service quality. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
