A brake system for a wheelchair is disclosed. The brake may comprise two assemblies one for each of the wheels. Each brake comprises a mounting bracket adapted to be connected to a frame portion of a wheelchair, a handle pivotally attached at a pivot point to the mounting bracket, a cable having one end connected to the handle and another end connected to a pivot arm. The pivot arm is pivotally attached to one end of a cam rod. The rod is attached to another mounting bracket adapted to be connected to another frame portion of the wheelchair and has a latching mechanism connected to a portion of the rod and biased into engagement with a splined disc by a spring. The disc is adapted to be connected to a hub of the wheel chair. In use, when the occupant of the wheel chair pivots the handle past a certain rotary position with respect to the pivot point of the handle, either in a forward or rearward direction, the spring forces the latching mechanism into either a positive braking engagement with the disc, thereby locking the wheelchair against movement, or a released position in which the wheelchair is free to move.
