Product Details

The PowerStop S4654C front brake caliper set is part of the PowerStop performance brake caliper line, which focuses on direct-fit replacement calipers for enthusiast vehicles. For Mustang owners looking for a front brake caliper replacement with a performance appearance, this caliper set combines remanufactured aluminum construction, floating caliper operation, and a red powder-coated finish that helps resist rust and corrosion. The design is pressure tested and assembled with new internal service components for consistent piston movement and dependable sealing. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Reasons to Replace

• Front caliper sticking or uneven brake release
• Brake fluid seepage from worn seals or bleeder hardware
• Corrosion on original front calipers
• Reduced braking response from worn piston components
• Cosmetic upgrade for a visible front brake assembly on a Ford Mustang

Installation Notes

Compatible With 1994-1998 Ford Mustang, front. Verify rotor, pad, and brake hose condition before installation, and confirm piston and bracket orientation matches the original front caliper setup. Bleed the brake system after installation and inspect for leaks, proper slide movement, and even pad contact. Mounting hardware is not listed as included.

Quality Assurance

PowerStop remanufactures the calipers and brackets in Chicago, IL and pressure tests each unit to confirm piston operation and help identify leaks before release. The kit uses new pistons, seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel brake pad abutment clips, along with high-temperature EPDM rubber dust boots and silicone lubricant for smoother operation in demanding conditions.
