This high-quality rebuild kit fits AP/Lockheed LD 19 calipers (1 5/8" diameter pistons). Each kit includes 2 piston seals, 2 dust seals, and 2 dust seal retainers (enough for one caliper).
Note 1: This kit is not manufactured by AP/Lockheed. We also offer genuine AP Racing Caliper Seals (Part No. 3580-1.625) individually.
Note 2: This kit is designed 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 3: AP/Lockheed calipers are specifically designed to compress the seals to size when they are installed in the caliper bore. The seals will be slightly oversize when they are loose.
