PowerStop S5030BLK Disc Brake Caliper Set - Rear

Rear Brake Caliper for GM Full-Size Trucks and SUVs

PowerStop S5030BLK is a rear disc brake caliper set built for select Cadillac, Chevrolet, and GMC applications. It uses a floating caliper design with a 51.05 mm phenolic piston, aluminum casting, and a black high-temperature powder-coated finish for a clean look behind stock or custom wheels.

PowerStop’s Rear High-Heat Black Powder Coated Brake Calipers line focuses on direct-fit replacement calipers that are remanufactured in Chicago, IL, then pressure tested for piston operation and leak prevention. The finish is made to resist rust and corrosion while the internal components are assembled with new pistons, seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel pad abutment clips.

What This Caliper Helps Address

• Rear brake drag caused by worn piston seals or slide components
• Uneven rear braking from sticking caliper operation
• Brake fluid leaks related to internal caliper wear
• Corrosion on exposed caliper surfaces in harsh conditions
• Reduced brake response from aging rear caliper hardware

Installation Notes and Tips

S5030BLK is a direct replacement rear caliper for the listed Cadillac Escalade, Chevrolet Tahoe, Silverado 1500, GMC Sierra 1500, and Yukon applications. Verify rotor, pad, and bracket compatibility before installation, and bleed the brake system after replacement to remove air from the hydraulic circuit. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Each PowerStop caliper is remanufactured and inspected in Chicago, IL, then pressure tested to confirm piston movement and help prevent leaks. The assembly uses new internal wear components and corrosion-resistant finishing to support consistent rear brake performance.
