Product Details

PowerStop Performance Brake Calipers are remanufactured for direct replacement service and are engineered to bolt in place of the stock rear calipers on the listed applications. The S4754 part number is part of PowerStop’s rear high-heat red powder coated brake caliper line, which focuses on durable finish quality, verified piston function, and clean OE-style fitment. This makes it a practical choice for rear brake caliper replacement on 2002-2010 Ford Explorer, 2001-2010 Mercury Mountaineer, 2003-2007 Jeep Liberty, 2003-2006 Jeep Wrangler, and 2003-2005 Lincoln Aviator applications.

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

What This Part Helps Address

• Rear brake fluid leaks from worn caliper seals
• Uneven rear braking caused by sticking or restricted piston movement
• Corrosion on original rear calipers and slide components
• Brake drag from deteriorated dust boots or slide hardware
• Faded appearance of exposed brake components behind open wheels

Quality Assurance

Each caliper is pressure tested to confirm piston operation and check for leaks before it leaves the remanufacturing facility. PowerStop also uses new internal service components and corrosion-resistant finishing to support consistent brake performance and long-term durability in rear brake service.
