How to use
Identify the caliper piston size and profile required by inspecting the damaged piston or consulting the vehicle service information. Select the matching piston from the kit and verify fit by measuring diameter and checking contact surface. Remove the caliper from the vehicle following manufacturer safety procedures, depress and extract the old piston, clean the caliper bore and seals thoroughly, and install the replacement piston ensuring proper alignment and lubrication of seals where applicable.
