ABSTRACT:
A variable ratio brake pedal assembly includes a support bracket having a mounting face and two spaced apart side arms extending from opposing edges of the mounting face. The brake pedal assembly also includes a pedal arm pivotally mounted to the support bracket at a first pivot point, and having a pedal pad mounted to a lower end of the pedal arm. The brake pedal assembly also includes a pedal link having a first end and a second end, such that the first end is pivotally connected to the pedal arm at a third pivot point, and a brake booster link having a first end and a second end, and the first end of the brake booster link is pivotally mounted to the second end of the pedal link at a fourth pivot point and the second end of said brake booster link is pivotally mounted to the support bracket at a second pivot point. The brake pedal assembly further includes a brake booster rod attaching means located on the brake booster link at a fifth pivot point, such that the fifth pivot point is located on the brake booster link so that a distance between the second pivot point and the fifth pivot point is less than a distance between the second pivot point and the fourth pivot point.
