The present disclosure provides steel backing plate wiredrawing equipment and method. The equipment includes a support frame; a first longitudinal rail and a second longitudinal rail which are respectively arranged on two sides of the support frame and are parallel to each other; a longitudinal movement frame slidably arranged on the first longitudinal rail and the second longitudinal rail; and a transverse movement frame slidably arranged on the longitudinal movement frame. A numerical control cutting machine, a vacuum cylinder, a glue dispenser, and a spot welder are integrated on the transverse movement frame; the longitudinal movement frame is provided with a power mechanism I, and the transverse movement frame is provided with a power mechanism II; the support frame is provided with a support plate; and the support plate is provided with a first laminate and a second laminate which are made of steel in sequence from bottom to top.

In order for hydraulic disk brakes to function properly over time, associated brake pads are changed periodically. In order to exchange old brake pads for replacement brake pads, a disk brake may require pushing back the brake pistons within a brake caliper body in order to make room for installation of replacement pads. Current tools and methods typically require removal of a wheel from a vehicle, removal of a brake rotor from the wheel, and/or removal of the brake caliper body from a rotor. The presently disclosed caliper piston tool allows brake pads to be replaced without dismantling various components of the vehicle, resulting in significant time and cost savings as well as convenience for do-it-yourself and professional mechanics alike.

A tool for retracting pistons into cylinder bores is disclosed, with a narrow gap between facing pressure plates allowing use of the tool in tight places, and ratcheting spreading of the facing pressure plates causing outward moving of the pistons, enabling work to be performed. One of the pressure plates is reversible to change the minimum narrow gap from a first width to a second width. In each of the orientations, the plates are movable towards and away from one another.

A piston resetting tool for a disk brake includes a main body, a first pressing plate, a second pressing plate and an operating rod. The side of the main body is connected to the first pressing plate, the second pressing plate is adjacent to the other side of the main body, and the operating rod is configured on one end of the main body. The inside of the main body is pivotally configured with a rotating piece and the rotating piece is configured with a middle tube through a first screw barrel in threaded joint. The middle tube is configured with a screw rod through a second screw barrel in threaded joint and the screw rod is connected to the second pressing plate, so that the second pressing plate can move to and fro.
