Abstract
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, wherein movement of a threaded stud through a coupler moves a first pressure plate.
Claims12
A disc brake piston retractor tool comprising:
- a first pressure plate carrying a threaded stud;
- a reversible wrench assembly operably connected to said threaded stud;
- a coupler carried by said reversible wrench assembly and receiving said threaded stud;
- a second pressure plate comprising a void space for receiving at least one of said coupler and said threaded stud within said void space of said second pressure plate;
- wherein the reversible wrench assembly is positioned between the first pressure plate and the second pressure plate;
- said threaded stud coupled to said first pressure plate at a first end, said threaded stud comprising a second end, said second end a free end selectively extending through said coupler and through and past said second plate;
- said coupler coupled to said second pressure plate;
- and
- said coupled interconnecting said first and second pressure plates.
