Abstract
A disk brake includes a disk rotor and a pair of pads. The pads are pressed against the disc rotor by a pressing device, so that a braking force is applied to the brake rotor. A shim is attached to each pad and opposes to the pressing device, so that a space is defined between the shim and each pad in order to retain a grease. Storage regions are defined within the shim in communication with the space in order to store and retain the grease. The storage regions are configured to retain the grease by utilizing the surface tension of the grease at least when the temperature of the grease is within a range of 20 to 200° C.
Claims13
A disk brake comprising:
- a disk rotor;
- a pair of pads with respective back plates;
- a pressing device arranged and constructed to press the pads against the disk rotor;
- a shim disposed between the back plate of each pad and the pressing device and defining a space for storing a grease between the shim and the back plate, the shim comprising a first shim member and a second shim member overlaid with each other and disposed on the side of the back plate and the pressing device, respectively, so that the space is defined between the first shim member and the back plate;
- and
- storage regions defined within the first shim member throughout the thickness of the first shim member in order to store and retain the grease;
- wherein:
- the storage regions are configured such that the grease substantially entirely covers the openings of the storage regions and is retained within the storage regions by the surface tension of the grease at least when the temperature of the grease is within a range of 20 to 200° C.
A disk brake comprising:
- a disk rotor;
- a pair of pads;
- a pressing device arranged and constructed to press the pads against the disk rotor;
- a shim attached to each pad and opposing to the pressing device, so that a space is defined between each pad and the corresponding shim in order to store a grease, and
- storage regions defined within the shim in communication with the space in order to store and retain the grease;
- wherein the storage regions are configured to retain the grease by the surface tension of the grease such that the grease is filled up within the storage regions at least when the temperature of the grease is within a range of 20 to 200° C.
