ABSTRACT:
A wheelchair with two large rear wheels, two swiveling front wheels and an open front has handgrips located vertically above the two rear wheels. A connecting rod pivoted to a handle attached to each of the handgrips extends downward to a plunger slidably located within a sleeve removably connected to the frame. An adjustable arm extends from the plunger through a slot in the sleeve to a position proximate yet not contacting each of the rear wheels. When a lever on the handle and each handgrip are squeezed the lever pivots and forces the rod and plunger downward within the sleeve. The arm on the plunger contacts each wheel and brakes the wheelchair.
