PowerStop S4690 Disc Brake Caliper Set - Rear

Overview

PowerStop S4690 is a rear disc brake caliper set built for performance-focused braking service. It is a direct bolt-in replacement for the original caliper assembly and is finished in high-temperature red powder coat for a clean, corrosion-resistant appearance.

Compatible With 1999-2000 Ford F-250 Super Duty and Ford F-350 Super Duty rear applications, plus 2000 Ford Excursion rear applications built before the listed cutoff dates. The S4690 is also a fitment match for rear brake service on these Ford trucks and SUV applications.

Key Features

• Floating caliper design with 2 pistons for controlled brake application.
• Cast iron caliper body with steel pistons for durable hydraulic operation.
• High-temperature red powder-coated finish helps resist rust and corrosion.
• Mounting bracket and caliper slides are included for the specified application.
• Pressure-tested assembly for piston operation and leak verification.

Product Details

PowerStop S4690 is part of the brand’s rear high-heat red powder coated brake caliper line, created for drivers who want a service replacement with a performance-oriented finish. The caliper is remanufactured in Chicago, Illinois and assembled with new pistons, seals, dust boots, bleeder screws, and stainless steel brake pad abutment clips. Its red coating is easy to clean and adds protection against corrosion while maintaining a consistent appearance behind the wheel.

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

Common Problems This Part Addresses

• Leaking caliper seals or fluid seepage.
• Sticky or uneven piston movement.
• Corrosion on the caliper body or finish.
• Brake drag caused by worn internal components.
• Reduced braking response from a failing rear caliper.

Installation Notes

Install as a direct replacement for the original rear caliper assembly on the listed Ford applications. Verify rotor condition, pad wear, and brake hose condition before installation. Bleed the brake system after installation and confirm proper piston movement and pedal feel before returning the vehicle to service.

Quality Assurance

PowerStop pressure-tests each caliper to verify piston operation and check for leaks. The remanufactured assembly uses new internal service components and a corrosion-resistant powder-coated finish for dependable brake service.
