Caliper Piston Tool. This caliper piston tool helps move or rotate compatible front or rear brake caliper pistons during brake service. Correct engagement and piston size help avoid torn dust boots, scratched pistons or uneven pad installation. Clean around the piston and watch fluid level before pushing pistons back into the caliper. Inspect piston plating, bore condition and seal grooves so hydraulic pressure moves the piston smoothly.
