This Carbon Piston Press is the safest way to reset hydraulic brake pistons when installing new pads (also serves as a bleed block)- Unlike screwdrivers or levers that can crack ceramic pistons or damage seals, this tool applies even pressure across both pistons at once- It pushes evenly across the piston faces, ensuring concentric and parallel retraction into the caliper bore, minimizing seal stress and avoiding the tilt that often occurs with improvised lever methods- Made from carbon-fiber reinforced polymer with titanium hardware, it's built for durability and effortless pad changes
