Abstract

A vehicle brake pedal has first and second master cylinders and the first pedal arm removably attached to the vehicle having a brake pedal foot pad movably attached thereto. A second brake pedal arm is operatively coupled to the first master cylinder and coupled to the brake pedal foot pad on one end portion thereof for movement of the second brake pedal arm responsive to movement of the brake pedal pad. A third brake pedal arm operatively coupled to the second master cylinder is coupled to the brake pedal foot pad on another portion thereof. The movement of the third brake pedal arm is responsive to movement of the brake pedal foot pad so that the brake pedal foot pad can be rotated to different angles on the first pedal arm to thereby apply different pressure to the first and second master cylinders by carrying the brake pedal foot pad while applying pressure.

Claims

1. A vehicle brake pedal comprising:

first and second master cylinders;

a brake pedal pivot pin attached to a vehicle;

a first pedal arm mounted on said brake pedal pivot pin;

a brake pedal foot pad having two end portions and being movably attached to said first pedal arm;

a second brake pedal arm operatively coupled to said first master cylinder and movably attached to said brake pedal pivot pin and coupled to said brake pedal foot pad on one end portion for movement of said second brake pedal arm responsive to movement of said brake pedal foot pad;

a third brake pedal arm operatively coupled to said second master cylinder and movably attached to said brake pedal pivot pin and coupled to said brake pedal foot pad on the other end portion thereof for movement of said third pedal arm responsive to movement of said brake pedal foot pad;

whereby applying pressure to said brake pedal foot pad while moving said foot pedal brake pad on said first brake pedal arm and applying pressure thereto varies the pressure applied to the first and second master cylinders to allow an operator to vary the force applies to said first and second master cylinders by the rotation of said brake pedal foot pad.

2. A vehicle brake pedal in accordance with claim 1 in which second brake pedal has a roller ball thereon for said brake pedal foot pad one end portion to ride on.

3. A vehicle brake pedal in accordance with claim 2 in which third brake pedal has a roller ball thereon for said brake pedal foot pad other end portion to ride on.

4. A vehicle brake pedal in accordance with claim 3 in which said first pedal arm is movably attached to a vehicle.

5. A vehicle brake pedal in accordance with claim 4 in which brake pedal foot pad has a bracket mounted thereto for movably attaching said brake pedal foot pad to said first pedal arm.
