Carlson 7809 Disc Brake Caliper Piston - Front

Carlson 7809 Disc Brake Caliper Piston

Carlson 7809 is a front disc brake caliper piston for brake hydraulic service on select Ford and Lincoln applications. It uses brake fluid pressure to move the caliper piston and press the brake pads against the rotor for stopping action.

• Disc brake caliper piston for front brake hydraulic repair
• Fits 2004-2009 Ford F-150, front
• Fits 2000-2009 Ford F-250, front
• Fits 1997-2002 Ford Expedition, front
• Fits 1998-2002 Lincoln Navigator, front
• Part number 7809 for brake caliper piston replacement

Brake Hydraulic Function

In a disc brake system, the caliper piston is a critical hydraulic component. When brake fluid pressure builds, the piston moves to clamp the pads against the rotor. On Ford F-150, Ford F-250, Ford Expedition, and Lincoln Navigator front brake applications, a properly functioning piston helps restore consistent caliper operation and braking response.

Common Repair Uses

• Restores caliper piston movement when the original piston is worn or damaged
• Addresses brake fluid leakage at the caliper piston area
• Helps correct uneven pad contact on the rotor
• Supports repair of front brake drag or sticking caliper symptoms
• Fits 2004-2009 Ford F-150 front brake service needs

Installation Notes

Inspect the caliper bore, seals, and brake fluid condition before installation. Clean all hydraulic surfaces thoroughly and follow the vehicle service procedure for the specific caliper design. Verify proper brake bleeding after assembly and confirm smooth piston movement before returning the vehicle to service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Carlson brake hydraulic components are built for service work where accurate fit and hydraulic function matter. Part number 7809 is intended for the listed front applications and should be matched to the vehicle’s caliper design before installation.
