Product Details

PowerStop S3224 is part of the PowerStop Rear High-Heat Red Powder Coated Brake Calipers line, a performance-focused caliper program for drivers who want direct replacement fitment with upgraded finish and rebuilt internals. For Subaru Legacy and Subaru Outback rear brake service, this caliper set is built to bolt into the stock location and maintain proper brake function while improving resistance to rust and corrosion. The red powder-coated surface is easy to clean and gives the rear brake assembly a more finished appearance behind stock or custom wheels.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Rear caliper sticking or uneven piston movement
• Brake fluid leakage from worn internal seals
• Corrosion on the caliper body or bracket
• Reduced brake response from worn slide hardware
• Cosmetic wear on visible rear brake components

Installation Notes and Tips

Verify rear fitment by year, make, model, and position before installation. Inspect brake pads, rotors, and brake hoses during service, and confirm the caliper slides move freely after installation. Bleed the brake system according to factory procedure after caliper replacement.

Quality Assurance

The caliper and bracket are remanufactured in Chicago, IL using new pistons, seals, dust boots, bleeder screws, and stainless steel brake pad abutment clips for the listed Subaru Legacy and Subaru Outback rear applications.
