Park Tool PP-1.2 Disc Brake Piston Press Pad Spreader Hydraulic Tool

Park Tool PP-1.2 Disc Brake Piston Return Press

The Park Tool PP-1.2 Disc Brake Piston Press is a professional-grade tool designed to safely and evenly retract hydraulic disc brake pistons during pad replacement, caliper alignment, and wheel installation. By sliding cleanly between the brake pads, the PP-1.2 spreads the pads apart while compressing the pistons back into the caliper body—making service fast, controlled, and damage-free.

Trusted by professional mechanics and home workshops alike, it’s an essential tool for maintaining smooth, quiet, and consistent disc brake performance.
