The Brake Booster in GMC Canyon vehicles plays an essential function of boosting up the brake system and diminishing the amount of force required from the driver. Located between the brake pedal and the master cylinder, it supports the force of the brakes by either vacuum or hydraulic means. The vacuum-operated boosters work on the basis of difference in vacuum pressure at the engine side and atmospheric pressure while hydraulic boosters use fluid pressure from power steering pump or electric pump. In the course of its production, GMC Canyon vehicles have used different designs of Brake Boosters: single and double diaphragm; the former can be in one or several sizes and with different colouring. In general, the booster with the larger diameter has all the more power assist to deliver but the double diaphragm booster can offer virtually as much assistance in less space. This versatility allows application specific brake pads for general use as well as for bespoke two-wheelers thereby providing the premier for each brake system.
