Vacuum Brake Booster: Description and Operation
Description
DESCRIPTION
The booster assembly consists of a housing divided into separate chambers by two internal diaphragms. The outer edge of each diaphragm is attached to
the booster housing. The diaphragms are connected to the booster primary push rod.
Two push rods are used in the booster. The primary push rod connects the booster to the brake pedal. The secondary push rod connects the booster (2) to
the master cylinder (1) to stroke the cylinder pistons.
The booster assembly is of the tie-bar design. This means the structural support of the assembly is through the tie-bars, whose ends protrude through the
booster shell. One end is the master cylinder mounting stud and the other end is the booster mounting stud. The booster assembly (with properly
functioning check valve installed) may not have a good vacuum seal unless the booster is installed on the dash panel mounting bracket with master
cylinder and booster mounting nuts properly torqued.
