This is a caliper rebuild kit for the Ate 2-piston caliper used on 1502, E21 320i/323i (front), and E26 M1 (rear) cars. It's enough seals and dust boots to rebuild one 2-piston caliper (both pistons in one caliper). Caliper seals are vital to the long-term health of your braking system and should be renewed regularly and any time damage is found. Compatible with original Ate calipers only.
