POWER BRAKE BOOSTER
DESCRIPTION
This vehicle uses a 205 mm tandem vacuum oper-
ated power brake booster (Fig. 42).
The power brake booster mounts on the engine
side of the dash panel (Fig. 43). It is externally con-
nected to the brake system by an input push rod to
the brake pedal. A vacuum hose connects the vacuum
check valve on the booster to the intake manifold.
The master cylinder is bolted to the front of the
booster.
The power brake booster can be identified (if
required) by the label attached to the body of the
booster. This label contains the following information:
• Production part number
• Build date
• Manufacturer
NOTE: The power brake booster assembly is not a
repairable part and must be replaced as a complete
unit if it is found to be faulty in any way. The check
valve (Fig. 42) used in the booster is not repairable,
but can be replaced as a separate component of the
power brake booster.
