spacer block (2) is located in between the cowl and the booster housing. The booster push rod (1), connects the booster to the brake pedal and master
cylinder (4), is attached to the center of the diaphragm. A check valve (5) is used in the booster outlet connected to the engine intake manifold. Power
assist is generated by utilizing a combination of vacuum and atmospheric pressure to boost brake assist.
