PowerStop S5212 Disc Brake Caliper Set - Rear

Rear Brake Caliper Set for Ford Flex and Lincoln MKS

PowerStop S5212 is a rear disc brake caliper set built for 2009 Ford Flex and 2009-2012 Lincoln MKS applications. It replaces the stock rear calipers with a direct-fit design and a high-heat red powder-coated finish that stands out behind stock or custom wheels.

PowerStop’s Rear High-Heat Red Powder Coated Brake Calipers line focuses on remanufactured performance calipers with corrosion-resistant coating, pressure testing, and updated internal components for consistent rear brake operation.

Key Features

• Direct replacement rear floating caliper set for select Ford and Lincoln vehicles
• High-temperature red powder-coated finish for easier cleaning and added rust resistance
• Remanufactured cast iron caliper body with steel piston
• 42.67 mm piston diameter
• Caliper slides and mounting bracket included where applicable
• 100% pressure tested to verify piston operation and check for leaks
• Assembled with new pistons, seals, dust boots, bleeder screws, and stainless steel brake pad abutment clips
• High-temperature EPDM rubber dust boots and premium silicone lubricant used for smoother operation

Detailed Description

PowerStop S5212 rear brake calipers are remanufactured in Chicago, IL and built to bolt directly in place of the original rear calipers on the Ford Flex and Lincoln MKS. The floating caliper design, cast iron construction, and 42.67 mm piston diameter support stable rear brake performance, while the red powder-coated finish helps resist corrosion and keeps the calipers looking clean behind the wheels. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear caliper sticking or uneven brake release
• Brake fluid leaks from worn internal seals
• Corrosion on original rear caliper housings
• Reduced piston movement from aged dust boots or slide components
• Worn rear caliper appearance on Ford Flex or Lincoln MKS brake systems

Installation Notes and Tips

Fits 2009 Ford Flex, rear. Fits 2009-2012 Lincoln MKS, rear. Verify rotor, pad, and brake hose condition during service, and bleed the hydraulic system after caliper replacement. Confirm bracket and slide orientation before final assembly. Part number S5212 is the correct reference for this rear application.

Quality Assurance

Each PowerStop caliper is pressure tested to confirm piston operation and help identify leaks before installation. The remanufacturing process includes new internal wear components and corrosion-resistant finishing for consistent service quality. Part number S5212 is built to PowerStop performance brake caliper standards for rear brake service on the listed Ford and Lincoln applications.
