Mechanical Follow-up Cable Adjustment
"Hornet" and "Wasp" Series
Disconnect cable from brake pedal and master
cylinder piston push rod from brake pedal.
Place a 31/2" spacer block between the brake
pedal rod pad and floor mat. Depress pedal rod
until pad contacts spacer block; retain in
that position and adjust the mechanical
follow-up cable length at the clevis end so
that the clevis pin can be installed freely
with no slack in the cable.
POWER BRAKES (TREADLE-VAC)
Power braking is a method of hydraulically
applying the wheel brake units with power
supplied by a pressure differential between
engine vacuum and atmospheric pressure. It is
actuated and controlled by a minimum amount
of
of minimum amount of foot pedal pressure.
The combined vacuum power unit and master
cylinder is an integral part of the brake system.
A vacuum reservoir tank is located in the
intake manifold vacuum line. Should a failure
occur in the vacuum system, this reserve supply
of vacuum will allow the operator to make
several power applications before the supply is
completely depleted.
When this occurs, the brakes may be applied
through physical effort alone as in a conven-
tional braking system, but more physical effort
is required due to the lack of a power assist.
The Treadle-Vac consists of three basic
elements combined into a single unit, the
vacuum power cylinder, piston and valve assem-
bly, and hydraulic cylinder and reservoir
assembly (Fig. 121.
