1. A brake booster assembly having a brake booster body and a pushrod with a pushrod axis along which the pushrod travels when being pushed, the brake booster assembly including a pushrod-pedal coupler, the pushrod-pedal coupler comprising
a pushrod-attachment end arranged on the pushrod and defining a longitudinal axis parallel to the pushrod axis;
a pedal-attachment end configured to be attached to a pedal and having a pedal pivot axis around which the pedal pivots when being pushed, the pedal pivot axis extending across the longitudinal axis;
a coupler hinge arranged between the pushrod-attachment end and the pedal-attachment end and connecting the pushrod-attachment end with the pedal-attachment end, wherein the coupler hinge has a coupler hinge axis that extends across the longitudinal axis and the pedal pivot axis and wherein the pedal pivot axis and the coupler hinge axis are offset along the longitudinal axis;
wherein the pedal pivot axis defines a first plane along which the pedal moves when being pushed, wherein the pedal pivot axis is perpendicular to the first plane, and the longitudinal axis and the coupler hinge axis are parallel to the first plane, wherein the coupler hinge axis defines a second plane, wherein the coupler hinge axis is perpendicular to the second plane, and the longitudinal axis and the pedal pivot axis are parallel to the second plane, and wherein the first plane and the second plane are perpendicular to each other.
