ACDelco Disc Brake Caliper Piston Seal Kit

The ACDelco Disc Brake Caliper Piston Seal Kit helps restore proper caliper operation when you rebuild a disc brake caliper. Worn or damaged piston seals can cause brake fluid leaks, sticking or dragging calipers, uneven pad wear, and a soft or inconsistent pedal. New seals help the caliper piston move and retract as designed. Use this kit as part of a caliper rebuild, or as a caliper seal replacement or repair kit.

Key Features:

• Replaces worn, hardened, or leaking caliper piston seals during a caliper rebuild
• Rubber sealing components are made to resist brake fluid, heat, and repeated pressure cycles
• Helps the piston retract correctly after the pedal is released, which supports even pad wear
• Backed by ACDelco, a brand with a long history of supplying OE-quality replacement parts
• Offered in multiple part numbers, so you can match the kit to your caliper application

Clean and inspect the caliper bore and piston during a rebuild. Replace the piston if it is pitted or scored. After reassembly, bleed the brake system and check for leaks before driving. Choose the specific part number that matches your caliper.
