Caliper piston tool for 360 degree swing brake compressor spreader1、360 Degree Swing Ratchet: There is a 360 degree rotating clamp ring in the middle of the two expansion plates, which can insert the clamp in any direction. It is more efficient and easier to operate. 2、Forward and Backward Switch: Turn the long handle to operate the Karaka and switch the reverse switch to switch between expansion and contraction. 3、Strong Adsorption Force: The strong absorption of the wrench' s magnet makes larger board groups less likely to fall off or deform, don't worry. 4、Rugged: The brake caliper piston uses a 1/8 inch thick quality steel expansion plate that is very tough. The oval handle is for a comfortable grip, even force, and non slip. 5、How to Use: Align the plunger on both sides while applying force to both sides of the plunger, turn the handle until the plunger has pushed the plunger into the correct position. 6、Versatile: This caliper piston tool is a very useful tool for changing brake pads, restarting pistons, replacing brakes, and other braking tasks.
