A control pedal for vehicles includes an assist mechanism to reduce the force require to operate the pedal over a portion of the pedal stroke. The assist mechanism includes a body having a first end pivotally connected to one of the frame and pedal arm and having a second end with a slot to slidably receive a pin mounted to the other of the frame and pedal arm. A biasing means acts between a portion of the body and a moveable stop on the body and the body is mounted between the pedal arm and the pin such that, when the pedal arm is in an "at rest" position, the pin acts against the moveable stop to compress the biasing means and as the pedal is moved from the "at rest" position, the biasing means exerts force between the pedal arm and the pin to assist the movement of the pedal arm along its stroke until the moveable stop reaches an end stop, after which further movement of the pedal arm is unassisted.
