The Park Tool PP-1.2 slides between disc brake pads inside the caliper, allowing the user to spread the pads and compress the hydraulic pistons when replacing pads, aligning pads, or performing other service procedures. The PP-1.2 expands the gap between the pads, making it easy to insert the disc between the pads when reinstalling a caliper or wheel. Dual density handle provides a positive grip. Fits into most hydraulic disc brake caliper bodies, including Shimano XTR.
