Carlson 7504 Disc Brake Caliper Piston - Front

Carlson 7504 Disc Brake Caliper Piston

The Carlson 7504 disc brake caliper piston is a front brake hydraulic component that uses brake fluid pressure to push the pads against the rotor. It is a direct-fit service part for select Chrysler, Dodge, Ford, Lincoln, and Mercury front disc brake applications, including vehicles using D33 brake setups and the D84 caliper repair kit application.

Key Features

• Disc brake caliper piston for front brake service
• Transfers hydraulic pressure to the brake pads during braking
• Fits select Chrysler Town & Country, LeBaron, New Yorker, and Newport applications
• Also fits select Dodge Aspen, Magnum, and Dart applications
• Compatible with Ford LTD and Thunderbird, plus Lincoln Continental and Mercury Colony Park and Marquis front disc brake applications
• Carlson part number 7504 for brake hydraulic repair work

Detailed Description

Brake performance depends on every hydraulic and friction component working together. The Carlson 7504 caliper piston is built for front disc brake service where the piston must move smoothly under fluid pressure to clamp the pads against the rotor. This part number 7504 is used across multiple classic vehicle brake applications, including 1968-1972 Ford LTD, 1968-1971 Ford Thunderbird, 1970-1972 Lincoln Continental, and 1968-1972 Mercury Colony Park and Marquis models. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake pedal travel caused by worn caliper piston surfaces
• Uneven pad contact from a sticking front caliper piston
• Reduced braking response in hydraulic disc brake systems
• Service needs during caliper repair on D33 and D84 brake applications
• Front brake rebuilds on Chrysler, Dodge, Ford, Lincoln, and Mercury vehicles

Installation Notes and Tips

• Confirm your vehicle’s front brake configuration before ordering.
• Inspect the caliper bore, seals, and brake fluid condition during service.
• Clean all mating surfaces thoroughly before reassembly.
• Bleed the brake system after installation to remove air from the hydraulic circuit.
• Verify fitment against the listed application and brake kit reference before installation.

Quality Assurance

Carlson brake hydraulic components are engineered for service use in brake system repair. The 7504 piston is listed for specific front disc brake applications to support accurate replacement selection.
