Brake performance is heavily dependent on proper pressure being delivered to the caliper. Whether it is a new build or diagnosing potential issues such as bad master cylinder, etc. You need to know what the pressure is to understand what is happening. This pressure gauge kit screws right into the place of a standard bleeder port allowing you to know true pressure at the caliper. With a built in bleeder you can properly bleed the system to know for sure.
