Front Brake Pads
Inspection and Replacement
1.
Nsvgr u9e an air hose or dry brush to clean brake
assemblies.
Use an OSHA approved vacuum cleaner to avoid
broathing brake dust.
Loosen the front wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the front wheels.
Remove the caliper bolt, and pivot the caliper up
out of the way. Check the hoses and pin boots for
damage and deterioration.

4. Using vernier calipers, measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thickness:
Standard: 10.5 - 11.5 mm {0.,11 - 0.45 in)
Servics Limit: 1.6 mm (0.06 in)
lf the brake pad thickness is less than the service
limit. replace the front pads and shims together as a
set.
Clean the caliper thoroughly; remove any rust, and
check for grooves and cracks.
Check the brake disc for damage and cracks.
Install the pad retainers.

Front Brake Disc
Disc Runout Inspection
l.Loosen the front wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the front wheels.
Remove the brake pads {see page 19-9).
Inspect the disc surface for damage and cracks.
Clean the disc thoroughly, and remove all .ust.
Use wheel nuts and suitable plain washers to hold
the disc securely against the hub, then mount a dial
indicator as shown, and maasure the runout at
10 mm (0.4 in) from the outer edge of the disc.
Brake Di3c Runout:
Service Limit: 0.10 mm {0.00,0 in)
WHEEL NUT ANDPLAIN WASHER108 N.m {11 kg{ m, 80 lbf.ft)
lf the disc is beyond the service limit, refinish the
brake disc with an on-car brake lathe. The Kwik-
Lathe produced by Kwik-way Manufacturing Co.
and the "Front Brake Disc Lathe" offered by Snap-
on Tools Co. are approved for this operation.
M8x. Rofinish Limit: 21.0 mm l0.8il in)
NOTE: A new disc should bs refinished if its runout
is greater than 0.10 mm (0.004 in).
Disc Thickness and Parallelism
Inspection
1.Loosen the front wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the front wheels.
Remove the brake pads (see page 19-9).
Using a micromater, measure disc thickness at eight
points, approximately 45'apan and 10 mm (0.4 in)
in from the outer edge of the disc. Replace the brake
disc if the smallest measurement is less than the
max. refinishing limit.
Brake Disc Thickness:
Standard:'97 - 98 modsls:
22.9 -23.1mm {0.90 - 0.91 inl'99 - 00 mod€ls:
23.6 - 23.8 mm {0.93 - 0.94 in}
Max. Refinishing Limit:21.0 mm (o.txl in)
Brake Disc Parallelism: 0.015 mm {0.0006 in} max.
NOTE: This is the maximum allowable difference
between the thickness measurements,
lf the disc is beyond the service limit for parallelism,
refinish the brake disc with an on-car brake lathe.
The Kwik-Lathe produced by Kwik-Way Manufac-
turing Co. and the "Front Brake Disc Lathe" offered
by Snap-on Tools Co. are approved for this opera-
tron.
NOTE: See section 18 for brake disc replacement.

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.

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.

2. Turn the ignition switch ON (ll).
NOTE; Do not press the brake pedal whenturningthe ignition switch.
3 Record the blinking frequency of the ABS indicator. The brinking frequency indicates the DTc.
4. Turn the ignition switch OFF. and remove the SCS service connector.NOTE: The Malfunction Indicator Lamp (MlL) will stay on after the engine is startsd if the SCS seryica connecror rsconnected.
5. Erase the DTC.
Conditions for DTC indication. The vehicle is stopped.. The SCS service connector is connected before the ignition switch is turned ON flt).. The brake pedal is released.. The SCS service connector remains connected during this procedure.

7. After four seconds. the indicator blinks twice for 0.3 second and the DTC is erased.
8. Confirm the DTC indication, and check that the DTC was erased.
NOTE: Always maintain these steps. lf you disconnect the SCS service connector and/or fail to operate the brake pedal
according to the indicator indication, the DTC will not be erased.
