shoes to rotate very slightly with the
drum, rocking an adjusting lever, thereby
causing rotation of the adjusting scr ew. Some drum brake systems are
designed to self-adjust duri ng application whenever the br akes are applied. This
on-board adjustment system reduces the need for maintenance adjustments
and keeps both the brake function and pedal feel satisfactory.
POWER BOOSTERS
Virtually all modern vehicles use a va cuum assisted power brake system to
multiply the braking force and reduce pedal effort. Since vacuum is always
available when the en gine is operating, the system is simple and efficient. A
vacuum diaphragm is located on the front of the master cylinder and assists the
driver in applying the brakes, reducing both the effort and travel he must put into
moving the brake pedal.
The vacuum diaphragm housing is normally connected to the intake manifold by
a vacuum hose. A check valve is placed at the point where the hose enters the
diaphragm housing, so that during periods of low manifold vacuum brakes
assist will not be lost.
Depressing the brake pedal closes o ff the vacuum source and allows
atmospheric pressure to enter on one side of the diaphragm. This causes the
master cylinder pistons to move and app ly the brakes. When the brake pedal is
released, vacuum is applied to both si des of the diaphragm and springs return
the diaphragm and master cylinder pist ons to the released position.
If the vacuum supply fails, the brake pedal rod will contact the end of the master
cylinder actuator rod and the system will apply the br akes without any power
assistance. The driver will notice that much higher pedal effort is needed to stop
the car and that the pedal f eels harder than usual.
VACUUM LEAK TEST
1. Operate the engine at idle without t ouching the brake pedal for at least one
minute.
2. Turn off the engine and wait one minute.
3. Test for the presence of assist va cuum by depressing the brake pedal and
releasing it several times. If vac uum is present in the system, light
application will produce less and less pedal travel. If there is no vacuum, air
is leaking into the system.
SYSTEM OPERATION TEST
1. With the engine OFF, pump the brake p edal until the supply vacuum is
entirely gone.
2. Put light, steady pressu re on the brake pedal.
3. Start the engine and let it idle. If the system is operating correctly, the brake
pedal should fall toward the floor if t he constant pressure is maintained.

either hold the ring gear or allow it to rotate
The accumulators are used to cushi on the engagement of the servos. The
transmission fluid must pass through the ac cumulator on the way to the servo.
The accumulator housing contains a thin piston which is sprung away from the
discharge passage of the accumulato r. When fluid passes through the
accumulator on the way to the servo, it must move the piston against spring
pressure, and this action smooths out the action of the servo.
HYDRAULIC CONTROL SYSTEM
The hydraulic pressure used to operat e the servos comes from the main
transmission oil pump. This fluid is channel ed to the various servos through the
shift valves. There is generally a manual shift valve which is operated by the
transmission selector lever and an automat ic shift valve for each automatic
upshift the transmission provides.
Many new transmissions are electroni cally controlled. On these models,
electrical solenoids are used to better control the hydraulic fluid. Usually, the
solenoids are regulated by an electronic control module.
There are two pressures which affect t he operation of these valves. One is the
governor pressure which is effected by vehicle speed. The other is the
modulator pressure which is effected by intake manifold vacuum or throttle
position. Governor pressure rises wit h an increase in vehicle speed, and

INTAKE MANIFOLD
REMOVAL & INSTALLATION
When servicing all vehicles, be absolutel y sure to mark vacuum hoses and
wiring so that these items may be properly reconnected during installation. Also,
when disconnecting fitting lines (fuel lines, power brake vacuum lines,
transmission and engine cooler lines, etc.), always use two flare nut (or line)
wrenches. Hold the wrench on the large fitti ng with pressure on the wrench as if
you were tightening the fitting (clockw ise), THEN loosen and disconnect the
smaller fitting from the larger fitting. If this is not done, damage to the line will
result. Always relieve fuel system pressure before disconnecting lines.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.
