Carlson 7690 Disc Brake Caliper Piston - Front

Carlson 7690 Front Disc Brake Caliper Piston

The Carlson 7690 disc brake caliper piston is a front brake hydraulics component built for vehicles that use disc brake calipers to apply braking force. It uses brake fluid pressure to push the brake pads against the rotor, helping restore proper caliper operation on a wide range of GM applications.

How the caliper piston works

In a disc brake system, the caliper piston is a critical hydraulic part that transfers pressure from the brake fluid into clamping force at the pads. Carlson 7690 is intended for front disc brake caliper repair on applications including Buick LeSabre, Pontiac Bonneville, Chevrolet Camaro, and Pontiac Firebird, along with additional Cadillac, Oldsmobile, and Buick front brake applications listed in the fitment data. This part number, 7690, is used where the original caliper piston has worn, seized, or lost sealing performance.

Common issues this part can address

• Brake drag caused by a sticking front caliper piston
• Poor brake response from hydraulic pressure loss at the caliper
• Uneven pad contact on the rotor
• Caliper service needs during front brake repair
• Restoration of proper piston movement in disc brake calipers

Installation notes and tips

Inspect the caliper bore, seals, and brake fluid condition before installation. Clean all mating surfaces carefully and verify that the piston matches the original caliper design for the listed vehicle application. After service, bleed the brake system and confirm smooth caliper movement and even pad engagement. For fitment confirmation, use the vehicle-specific listing for your front brake application.

Quality assurance

Carlson manufactures brake hardware and hydraulic service parts for repair applications where the brake system must work as a complete assembly. Part number 7690 is cataloged for front disc brake caliper use on the supported Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac vehicles listed above.
