Over several decades, the internal rubber diaphragm of the original booster can dry out and crack. When this happens, the \"power assist\" is lost, making the Bus difficult and dangerous to stop in modern traffic. Replacing the booster restores the smooth, responsive braking these vehicles were known for at the end of their production run.\u003c\/p\u003e\n\u003cp data-path-to-node=\"11\"\u003eThis unit is designed to work in conjunction with the dual-circuit master cylinder.
