A brake vacuum aspirator has a generally known construction and function and includes an optimized bypass flow path including an optimized check valve making the brake vacuum aspirator capable of a performance level not previously obtainable in brake vacuum aspirators. In particular, the brake vacuum aspirator of the exemplary embodiment of the present disclosure includes an enlarged bypass flow path for providing a proximately 9.5 ft3/min of air flow at 7″ of Hg so that the brake vacuum aspirator is capable of sufficient performance during alternating wide-open throttle and then full brake application testing simulating high performance driving such as those that may be experienced in vehicle pursuits (e.g., Police City Pursuit Testing) without using any added and costly additional equipment.
