Abstract
A force transmission device for a disc brake operable to move a friction element of the brake into engagement with a rotary brake disc along a first axis in response to a loading from an actuating member, the device comprising: a guide member having a generally cylindrical guide form; a piston comprising a complementary generally cylindrical outer sliding surface slideable within the guide member, wherein; an anti-rotation formation is provided between the guide member and the piston, the formation comprising a recess extending generally parallel to the first axis and a complementary projection.
Claims14
A disc brake caliper comprising:
- a housing;
- a cover plate having a major plane;
- a piston;
- and
- a rotating shaft;
- wherein the cover plate has a first aperture therein through which the piston extends to move a friction element into engagement with a rotor;
- wherein the housing includes an opening on a side configured to face the rotor and the cover plate is mounted over the opening to substantially seal the housing;
- and
- wherein the cover plate has a first bearing form upon which the rotating shaft is disposed, the first bearing form having a substantially circular wall, a second wall, and an end wall, wherein the substantially circular wall extends away from the major plane and is spaced apart from and extends continuously around the second wall, the second wall extends back toward the major plane to the end wall, and the second wall and the end wall cooperate to form a blind substantially cylindrical bore that receives the rotating shaft.
