Abstract
A brake pedal mechanism limits the reaction force applied on a brake pedal lever pivot. The pivot is formed by a slot closed by a tang yieldably connected to a retaining arm of a pivotable release lever. A release arm of the release lever is engagable by an actuating rod of a brake booster when moved beyond the normal travel limit of the rod. In one case, excessive brake pedal force causes the tang to yield and release the brake pedal pivot pin. In another case, excess rearward motion of the actuating rod pivots the release lever, lifting the tang and freeing the pivot pin. In either case, the reaction force on the pivot is maintained below a desired limit.
