The booster must be replaced as anassembly if diagnosis indicates a malfunction hasoccurred.OPERATIONTheboosterunitconsistsofasinglehousingdivided into two by a tandem diaphragm. The outeredge of the diaphragm is secured to the housing. Thebooster push rod, which connects the booster to thebrake pedal and master cylinder, is attached to thecenter of the diaphragm. A check valve is used in thebooster outlet connected to the engine intake mani-fold. Power assist is generated by utilizing a combi-nation of vacuum and atmospheric pressure to boostbrake assist.
