Abstract:
A cable disc brake comprising:a caliper housing having a plurality of first holes arranged along a first circumferential arc with a first end hole defining one end of said first circumferential arc and a second end hole defining the other end of said first circumferential arc; a first friction member movably coupled to said caliper housing between a release position and a braking position; a second friction member coupled to said caliper housing and arranged substantially parallel to said first friction member to form a rotor receiving slot therein between; a cable actuated mechanism movably coupled to said caliper housing to move said first friction member from said release position towards said second friction member to said braking position, said cable actuated mechanism having a plurality of second holes arranged along a second circumferential arc with a first end hole defining one end of said second circumferential arc and a second end hole defining the other end of said second circumferential arc; and a torsion spring having a first end received in one said first holes of said caliper housing and a second end received in one said first holes of said cable actuated mechanism to urge said cable actuated mechanism to said release position, said first and second ends of said torsion spring being axially aligned when said torsion spring is in an unloaded rest position, said caliper housing and said first end of said torsion spring being configured to be adjustable relative to each other to change an effective biasing force of said torsion spring by changing which of said first holes is coupled to said first end of said torsion spring, said cable actuated mechanism and said second end of said torsion spring being configured to be adjustable relative to each other to change said effective biasing force of said torsion spring by changing which of said second holes is coupled to said second end of said torsion spring, said first end holes being axially aligned and said first and second circumferential arcs extending in circumferentially opposite directions from said first end holes to said second end holes when said cable actuated mechanism is in a brake releasing position, said second end holes having centers circumferentially spaced about 90 degrees from each other when said cable actuated mechanism is in said brake releasing position, said first holes being circumferentially spaced apart by a different angular amount than said second holes.
