Cable disc brake

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 including an actuating arm and a cam assembly 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 actuating arm having a biasing member receiving recess and 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 biasing member arranged in said biasing member receiving recess, said biasing member having a first end coupled to said caliper housing and a second end coupled to said actuating arm to urge said cable actuated mechanism to a brake releasing position, said caliper housing and said first end of said biasing member being configured to be adjustable relative to each other to change an effective biasing force of said biasing member, said cable actuated mechanism and said second end of said biasing member being configured to be adjustable relative to each other to change said effective biasing force of said biasing member, said first and second ends of said biasing member being axially aligned when said biasing member is in an unloaded rest position,
• said cam assembly including a first cam member having a set of first camming surfaces and a second cam member having a set of second camming surfaces with rolling members located between said first and second camming surfaces,
• said first cam member being rotatably mounted within said caliper housing but non-movably mounted in the axial direction, and said second cam member being movably mounted in the axial direction but non-rotatably mounted, said first cam member having an operating shaft extending out of said housing that is removably coupled to said actuating arm,
• 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 said 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.
