Park Tool Hydraulic Brake Piston Press, Brake Spreader

The Park Tool Hydraulic Brake Piston Press is a workshop tool designed to safely and evenly push hydraulic disc brake pistons back into the caliper during pad changes or service.

It helps reset pistons without damaging seals, pads, or rotor surfaces, making brake maintenance faster and more controlled. The wide, flat pressing surface spreads force evenly so pistons retract smoothly instead of sticking or cocking.
