BRAKES
The brakes are of the single anchor Duo Servo construction and are equally
effective in both forward and reverse directions. This construction also brings
all of the lining into equal action, giving greater braking action per square inch
of surface than other types. This equal pressure of the lining around almost the
entire circumference, of the brake drums reduces the tendency for distortion of
the drum and prevents localized high lining pressures which cause rapid wear,
scoring and squeaking.
The brake pedal and hand brake lever are located in the conventional
position.
Both the brake pedal and lever are connected to operate a short, sturdy
equalizer, pivoted to the underside of the frame "X" member. The motion of
the equalizer is transmitted to the brake shoes through cables.
The operation of the brakes through pre-stretched cables and equalized
action cam levers insures equal braking effort at each wheel and long life
between brake adjustments.
It is necessary to have the brakes adjusted to offset normal wear when the
brake pedal can be depressed within 1/2" of the floor. This adjustment is made
as follows:
Jack up all four wheels clear of the
ground. Remove wheels from hubs.
Remove inspection hole cover on
drums. Place a .010" feeler gauge
through the brake drum inspection
hole between the lining of the upper
shoe and the drum. Loosen the
eccentric lock nut (A), Figure 14, and
turn the eccentric (B) in the direction
of forward wheel rotation until the
feeler is held snug. Tighten lock nut
(A). The clearance around the lining
of the upper shoe should not vary
more than .003". If a greater varia-
tion exists, a major adjustment
should be made by an Authorized
Terraplane and Hudson Service Sta-
tion. Turn the star wheel with a
screwdriver inserted through the ad-
justing hole (C), moving the handle toward the center of wheel. Continue
turning until a drag is felt when the brake drum is turned. Then turn star wheel
in the reverse direction just until the drum turns free. Replace the inspection
hole cover and wheels.
After performing the above operations on all four wheels, pull the hand
brake lever up one or two notches until a firm drag is felt when turning the
