Keep your AP Racing / Lockheed calipers working properly by rebuilding with these genuine AP Racing piston seals!
This set of two piston (fluid) seals is for certain AP Racing/Lockheed calipers with 2.0" (50.8mm) diameter pistons, including AP CP2382 and CP2383. These seals are manufactured specifically for racing use. Sold in pairs (2 seals), each kit is enough for a single 2-piston caliper.
Note 1: These seals are for AP/Lockheed seal-in-bore calipers only. They do not fit AP Racing seal-on-piston calipers or any other brand of calipers. Brakes are a critical safety component. We strongly recommend against trying to use these seals in other brands of calipers, even if the nominal piston size is the same. The results of brake system failure can have devastating effects!
Note 2: These seals get compressed to size when they are installed in the caliper bore. This is required for a tight seal. They will be slightly oversize (up to about 0.10" larger than the nominal size) when they are loose. They will not fit tight against the piston until they are installed in the caliper bore.
Note 3: The CP4518 Series seal kits include the fluid (pressure) seals only. They do not include dust seals.
