PowerStop S4830 Disc Brake Caliper Set - Rear

Overview

PowerStop S4830 is a rear disc brake caliper set built for direct replacement service and performance-focused use. It is compatible with 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator rear applications, with a red powder-coated finish that stands out behind the wheel.

This PowerStop brake caliper set is remanufactured with a floating design, cast iron housing, and steel piston components. The S4830 part number is a fitment-specific option for drivers replacing worn rear calipers on Ford Expedition and Lincoln Navigator models.

Key Features

• Direct-fit rear brake caliper set for compatible applications
• High-temperature red powder-coated finish for corrosion resistance
• Remanufactured with new pistons, seals, dust boots, bleeder screws, and pad abutment clips
• Floating caliper design with slides included
• Pressure tested for piston operation and leak prevention
• Cast iron caliper body with steel piston material

Product Details

PowerStop S4830 is engineered as a bolt-in replacement for the original rear caliper assembly. The remanufactured construction uses a cast iron caliper body, a single 51.82 mm piston, and a floating caliper layout to match the original braking function. The red powder-coated finish helps resist rust and corrosion while giving the caliper a clean appearance behind stock or custom wheels. The S4830 is a practical choice for restoring rear brake performance on Ford Expedition and Lincoln Navigator vehicles when the original calipers are worn, sticking, or leaking.

PowerStop remanufactures these calipers and brackets in Chicago, Illinois, then pressure tests each unit to verify piston movement and check for leaks. The included bracket and slide components support a complete replacement of the rear caliper assembly where applicable. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Brake fluid leakage from a worn caliper seal
• Sticking or uneven rear brake operation
• Corrosion on the caliper body or piston area
• Poor brake pad contact caused by worn slide components
• Reduced braking performance from a damaged rear caliper assembly

Installation Notes

Verify rear fitment before installation on 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator models. Transfer and bleed the brake system according to service procedures after replacement. Inspect brake pads, rotors, and brake hoses during installation to confirm the rest of the braking system is in serviceable condition.

Quality Assurance

PowerStop pressure tests each caliper to confirm piston operation and help prevent leaks. The remanufactured finish and internal components are selected to support consistent brake function and corrosion resistance in demanding conditions.
