Carlson 7898 Disc Brake Caliper Piston - Rear

Carlson Disc Brake Caliper Piston 7898

The Carlson Disc Brake Caliper Piston 7898 is a rear brake hydraulic component built to transfer brake fluid pressure into clamping force at the caliper. In a properly functioning brake system, the piston helps press the pads against the rotor so the vehicle can slow and stop with consistent pedal response.

Designed for rear applications on select Chevrolet Silverado, GMC Sierra, and Chevrolet Suburban HD models, this part line focuses on brake system service where accurate caliper operation matters. If you are replacing a worn or damaged rear caliper piston on a 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, Carlson 7898 is a direct-fit service part for the listed applications.

Key Features

• Disc brake caliper piston for rear brake hydraulic service
• Uses brake fluid pressure to move the caliper piston during braking
• Application-specific fitment for select Chevrolet and GMC heavy-duty trucks
• Suitable for rear brake repairs on Silverado, Sierra, and Suburban HD platforms
• Part number 7898 for cataloging and cross-reference use

Detailed Description

Carlson’s Disc Brake Caliper Piston line is built around the brake system’s hydraulic function, where the piston converts fluid pressure into the force needed to clamp the pads against the rotor. This part number 7898 is listed for rear brake applications across 2011-2019 Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, GMC Sierra 3500 HD, and 2016-2018 Chevrolet Suburban 3500 HD configurations shown in the fitment data. It also covers related Silverado, Sierra, and Cheyenne rear applications noted for D1411 and D1565 service references.

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

What It Helps Address

• Rear brake caliper piston wear or scoring
• Uneven pad contact caused by piston-related caliper issues
• Brake fluid pressure transfer problems at the caliper
• Brake service needs on Silverado, Sierra, and Suburban HD rear brakes
• Restoration of proper caliper movement during brake repair

Installation Notes and Tips

Verify the vehicle year, make, model, and rear brake configuration against the fitment list before ordering. Match the existing caliper service reference, including D1411 or D1565 notes where listed, to confirm application accuracy for your Chevrolet Silverado, GMC Sierra, or Chevrolet Suburban HD.

During installation, inspect the caliper bore, seals, pads, and rotor condition so the new piston is installed into a clean, serviceable brake assembly. Follow the vehicle manufacturer’s brake service procedures and bleed the hydraulic system after any brake hydraulic work.

Quality Assurance

Carlson manufactures brake hardware and hydraulic service components for brake system repair applications. This piston is intended for the listed rear fitments and should be selected by exact vehicle application and brake service reference.
