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.
Claims2
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 second pressure plate comprising a void space for receiving said threaded stud within said void space of said second pressure plate;
- said stud secured to said second pressure plate;
- a coupler carried by said reversible wrench assembly, and said coupler interconnecting said first and second pressure plates.

A disc brake piston retractor tool comprising:
- a first pressure plate carrying a threaded stud along an axis perpendicular to said first pressure plate, the stud defining an external thread;
- a second pressure plate comprising a void space for receiving said threaded stud within said void space of said second pressure plate;
- a reversible wrench assembly operably connected to said threaded stud, said reversible wrench assembly providing selective reversible rotation of the coupling relative to at least one of the first pressure plate and the second pressure plate;
- a coupler carried by said reversible wrench assembly, and said coupler coupling said first and second pressure plates;
- the coupler comprising a groove at a proximal end, wherein at least a portion of the coupler is positioned within the void space of the second pressure plate and a retaining ring is installed in the groove, wherein the coupling defines an internally threaded bore;
- whereby selective rotation of the ratcheting wrench assembly causes threading and unthreading of the stud in the bore and movement of at least one of the pressure plates along the axis in relation to the other pressure plate.
