Abstract

A hydraulic brake caliper piston/plunger tool includes a handle, a barrel with rear and front tubes, and a shaft. The handle is provided therein with a fluid reservoir and a fluid chamber, and pivotally connected with an operation lever having a plunger inserted into the fluid chamber. The shaft is attached with a piston and fitted through the rear tube, the barrel and the front tube. A return spring is fitted around the shaft in a central hole of the barrel, between the piston and the front tube. A front end of the shaft is adapted to be fitted with an accessory for a disc brake. A rear end of the shaft is adapted to be connected with a turning tool. In use, alternately depressing and releasing the operation lever enables fluid to enter the central hole of the barrel to have the piston together with the shaft moved forward.
