The 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®. The unique shape and size of the PP-1.2 is perfect for compressing the hydraulic piston by pushing the brake pads apart to speed service and pad replacement. Useful if you have accidently pulled the brake lever without your wheel and brake disc in the bike. Updated shape to better fit 2011 and later Shimano XTR calipers. Slide the polished, wedge shaped tool between pads to expand the gap and pre-set the pistons into the calliper Reset the pistons without disassembling the calliper or removing the brake pads
