Brake Pedal
Pedal Hoight
1. Disconnect the brake switch connector, loosen the
brake switch locknut, and back off the brake switch
until it is no longer touching the brake pedal.
2. Lift up the carpet, At the insulator cutout, measure
the pedal height from the middle of the right side of
the oedal pad.
BRAKE SWITCH
ERAKE SWITCH
Standard Pedal Height (with floor m8i removed):
A/T: 161 mm (5 5/16 in)
M/T: 155 mm {6 U8 in}
Loosen the pushrod locknut, and screw the pushrod
in or out with pliers until the standard pedal height
from the floor is reached. Do not adjust the pedal
height with the pushrod pressed. After adiustment,
tighten the locknut firmly.

4. Screw in the brake switch until its plunger is fully
pressed (threaded end touching the pad on the
pedal arm), Then back otf the switch 1/4 turn to
make 0.3 mm (0.01 in) of clearance between the
threaded end and pad. Tighten the locknut firmly.
Connect the brake switch connecto.. Make sure that
the brake lights 90 off when the pedal is released
5. Checkthe brake pedalfree play as described below
Pedal Free Play
1. With the engine off. inspect the free play on the
pedal pad by pushing the pedal by hand-
Free Play: 1 - 5 mm (1/16 - 3/16 in)
2. lf the pedal free play is out of specification, adiust
the brake switch. lf the pedal free play is insuffi-
cient, it may result in brake drag.

1. Remove the reservoir cap. Check that the float
moves up and down freely; if it doesn't, replace the
reservoir cap assembly.

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.
