absoluteBLACK Hydraulic Brake Piston Press

The absoluteBLACK Piston Press is a lightweight, workshop-quality tool engineered to safely reset hydraulic brake pistons without damaging seals or ceramic faces. Unlike improvised tools like screwdrivers or tire levers—which often tilt pistons or crack them—the Piston Press applies even, parallel force to both pistons simultaneously, ensuring fast and concentric retraction into the caliper.

Also serves as a bleed block during maintenance. Constructed from carbon-fiber–reinforced polymer, with titanium bolt, aluminum wedge, and rubber O-rings, it offers durability without compromise. Weighing just 12.5g, it’s perfect for workbench setups or weight-conscious on-the-go tool kits.
