Application: Pressing back the brake pistons on hydraulic disc brakes on bicycles. Easy to use and safe to work with. For two-piston brake systems with an opening over 20 mm. Working range: 4 - 15 mm. The toggle lever principle makes it easy to reset the brake pistons with little effort. Double dip coating. Easy to use: Position the pliers between the brake pistons (without brake pads) and press the pliers legs together. No need to remove the wheel. Safe working: Parallel spreading process avoids risk of jamming or damage to the brake pistons, especially with ceramic brake pistons. The method of actuation provides the user with feedback on the movement of the pistons. Tip: Open the expansion reservoir before pushing back the pistons. Only push the pistons back until they are flush with the brake calliper. When the wheel is fitted, make sure that the brake disc is between the plates.
