Product Details

PowerStop’s brake caliper line focuses on enthusiast-grade replacement parts that bolt into the original location and restore front braking function without changing the vehicle’s factory setup. S4790 is assembled with new pistons, seals, dust boots, bleeder screws, and stainless steel brake pad abutment clips, then pressure tested to verify proper piston movement and sealing. The high-temperature EPDM dust boots and silicone lubricant support smooth operation in demanding driving conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Sticking or uneven front brake caliper movement
• Brake fluid leaks at the caliper body or piston seal
• Corrosion on the caliper housing and bracket
• Reduced braking response from worn internal components
• Brake pad drag caused by worn slides or piston issues

Installation Notes

Fits 1999-2004 Ford F-250 Super Duty, front. Fits 1999-2004 Ford F-350 Super Duty, front. Fits 2000-2005 Ford Excursion, front. Verify rotor, pad, and brake hose condition before installation, and confirm the caliper side and mounting points match the original front brake setup on your Ford F-250 Super Duty, Ford F-350 Super Duty, or Ford Excursion. Bleed the brake system after installation and inspect for leaks and proper pedal feel.

Quality Assurance

Each PowerStop S4790 caliper is pressure tested to confirm piston operation and sealing integrity before release. The remanufacturing process uses new wear components and corrosion-resistant finishing to support consistent front brake performance.
