lf the clearance between the gauge body and
adjusting nut is 0.4 mm (0.02 in), the pushrod-to-
piston clearance is 0 mm. However. if the clearance
between the gauge body and adjusting nut is 0 mm,
the pushrod-to-piston clearance is 0.4 mm (0.02 in)
or more. Therefore it must be adjusted and
recheck€d.
lf clearance is incorrect, loosen the star locknut, and
turn the adjuster in or out to adjust.
. Adjust the clearance while the specified vacuum
is applied to the booster.
. Hold the clevis while adjusting.
Tighten the star locknut securely.
Remove the special tool.

Brake Booster Inspection
FunctionalTest
1. With the engine stopped, press the brake pedal sev-
eral times to deplete the vacuum reservoir. thenpress the pedal hard, and hold it for 15 seconds. lf
the pedal sinks, either the master cylinder is
bypassing internally, or the brake system (master
cylinder, lines, modulator, proportioning valve. or
caliper) is leaking.
2. Start the engine with the pedal pressed. lf the pedal
sinks slightly. the vacuum booster is operating nor-
mally. lf the pedal height does not vary, the booster
or check valve is faultv.
3. With the engine running, press the brake pedal light-
ly. Apply just enough pressure to hold back auto-
matic transmission creep. lf the brake pedal sinks
more than 10 mm (3/8 in.) in three minutes, the mas-
ter cylinder is faulty. A slight change in pedal height
when the Ay'C compressor cycles on and off is nor-
mal. (The Ay'C compressor load changes the vacuum
available to the booster.)
Leak Test
1.Press the brake pedal with the engine running, then
stop the engine. lf the pedal height does not vary
while pressed for 30 seconds, the vacuum booster is
OK. lf the pedal rises, the booster is faulty.
With the engine stopped, press the brake pedal sev-
eral times using normal pressure. When the pedal is
first pressed. it should be low, On consecutive appli-
cations, the pedal height should gradually rise. lf thepedal position does not vary. check the booster
check valve.
Boostor Chock Valve Test
1. Disconnect the brake booster vacuum hose at the
booster.
2. Start the engine, and let it idle. There should be vac-
uum. lf no vacuum is available, the check valve is
not working properly. Replace the brake booster
vacuum hose and check valve. and retest.

Rear Drum Brakes
Never use an air hose or dry brush to clgan brake assemblies,
Use an OSHA approved vacuum cleaner to avoid breathing brake dust.
Contaminated brake linings or drums reduce stopping ability.
Block the front wheels betore iacking up lhe rear ot the vehicle,
Block the front wheels, loosen the rear wheel nuts slightly, then raise the
poned. Remove the rear wheels.
2. Release the parking brake, and remove the rear brake drum.

Anti-lock Brake System (ABS)
Features/Construction
When the brake pedal is pressed during driving, the wheels can lock before the vehicle comes to a stop. In such an event,
the maneuverability of the vehicle is reduced if the front wheels are locked, and the stability of the vehicle is reduced if the
rear wheels are locked, creating an extremely unstable condition. The ABS precisely controls the slip rate of the wheels to
ensure maximum grip force from the tires, and it thereby ensures maneuverbility and stability of the vehicle.
The ABS calculates the slip rate of the wheels based on the vehicle speed and the wheel speed, then it controls the brake
fluid pressure to attain the target slip rate.

ABS Modulator
The ABS modulator consists of the inlet solenoid valve, outlet solenoid valve, reservoir, pump, pump motor and thedampjng chamber.
The modulator reduces the caliper fluid pressure directly. lt is a circulating-type modulator because the brake fluid circulatesthrough the caliper, reservoir and the master cylinder.The hydraulic control has three modes: pressure reduction, pressure retaining and pressure intensifying modes.The hydraulic circuit is the independent four channel-type, one channel for each wheel.
SOLENOID VALVE
t-
Pressure intensifying mode: Inlet valve open, outlet valve closed,
Pressure retaining mode:
Pressure reduction mode:
Motor operation mode:
Master cylinder fluid is pumped out to the caliper.Inlet valve closed, outlet valve closed.
Caliper fluid is retained by the inlet valve and outlet valve.Inlet valve closed, outlet valve ooen
Caliper fluid flows through the outlet valve to the reservoir.When starting the pressure reduction mode. the pump motor is ON.When stopping ABS operation, the pump motor is OFF.The reservoir fluid is pumped out by the pump, through the damping chamber, to the mastercylinder.
