Abstract
In a disc brake mechanism having a caliper mechanism which is mounted on the axle housing and which has brake pads in embracing relation to a rotor, an actuating means for the brake includes a pair of oppositely extending "scissors-type" levers pivotally mounted on the caliper mechanism, the outer end of one of the levers being attached to an actuating cable and the outer end of the other one of the levers being attached to a sheath of the cable. Stop means is provided for preventing the movement of the other lever in the direction of movement of the cable when the cable is actuated. In one embodiment, a stop is formed on the caliper mechanism bracket for engaging the other lever and in another embodiment, a projection is formed on the other lever to engage a portion of the caliper mechanism bracket.
Claims3
A disc brake mechanism having a pair of brake plates with brake pads that are carried by a caliper that is mounted on an axle housing comprising:
- in combination, a rotor adapted for rotation with the end of an axle external of the axle housing, a portion of the periphery of said rotor extending between the brake pads;
- spring means for urging the brake plates apart;
- means for actuating the caliper mechanism for axially squeezing the pads against said rotor, said actuating means including a pair of actuating levers that are pivotally mounted on a caliper mechanism bracket, the inner end of each of said levers being engaged with the inner one of the brake plates, the outer end of one of said levers being attached to an actuating cable and the outer end of the other one of said levers being attached to a sheath of said cable and stop means on the caliper mechanism bracket for preventing the movement of said other lever in the direction of movement of said cable when said cable is actuated.
