Inspection and Adjustment
Parking Brake
Inspection
1. Pull the parking brake lever with 196 N {20 kgf. 44 lbf)
force to fully apply the parking brake. The parking
brake lever should be locked within the sDecified
number of clicks.
Lever Locked clicks: 6 - I

2. Adjust the parking brake if the lever clicks are out of
specification.

NOTE: After servicing the rear brake pads or calipers, or
the rear brake shoe, loosen the parking brake adjusting
nut, start the engine, and depress the brake pedal sever-
al times to set the self-adjusting brake before adjusting
the parking brake.
1. Raise the rear wheels off the ground, and support
the vehicle on safety stands.

Pullthe parking brake lever up one click,
Tighten the adjusting nut until the rear wheels drag
slightly when turned.
Belease the parking brake lever fully, and check that
the rear wheels do not drag when turned. Readjust
if necessarv.
Make sure that the parking brakes are fully applied
when the parking brake lever is pulled up fully.
Reinstall the rear console.

NOTE: There are two types of front brake calipers:
The caliper types can be identified by the "5410" or"2056" stamped on the caliper body as shown below.
Check the type of the brake caliper before servicing.

NOTE: For 2056 type disassembly procedures. see page
19-'10.
Never use an air hose or dry brush lo clean brake
assgmblios.
Use an OSHA approved vacuum cleaner to avoid
breathing brake dust.
Loosen the front wheel nuts slightly, then raise the
vehicle, and support it on safety stands. Remove
the front wheels.
Remove the brake hose bracket from the knuckle.
Remove the caliper bolt, and pivot the caliper up

NOTE: When the caliper is equipped with an outer
pad shim, replace the shim together with the pads
5. Using vernier calipers, measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thickno$:
Standard: 9.5 - 10.5 mm 10.37 - 0.41 in)

NOTE: Inspect the brake hose for interference or
twisting.
Depress the brake pedal several times to make sure
the brakes work. then test-drive.
NOTE: Engagement of the brake may require a
greater pedal stroke immediately after the brake
pads have been replaced as a set. Several applica-
tions of the brake pedal will restore the normal
Dedal stroke.
After installation. check for leaks at hose and line
joints or connections, and retighten if necessary.

2.
Loosen the front wheel nuts slightly, then raise the
vehicle, and support it on safety stands. Remove
the front wheels.
Remove the brake pads (see page 19,8).
Inspect the disc surface for damage and cracks.
Clean the disc thoroughly and remove all rust.
Use wheel nuts and suitable plain washers to hold
the disc securely against the hub, then mount a dial
indicator as shown, and measure the runout at
10 mm (0.4 in) from the outer edge of the disc.
Brake Disc Runout:
Service Limit: 0.10 mm (0.004 inl
WHEEL NUT ANOPLAIN WASHER'108 N.m(11 kg{.m, 80 lbf.ft)
lf the disc is beyond the service limit, refinish thebrake 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.
Max. Refinish Limit: 19.0 mm (0.75 in)
NOTE: A new disc should be 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 support it on safety stands. Remove
the front wheels.
Remove the brake pads (see page 19-8).
Using a micrometer, measure disc thickness at
eight points, approximately 45" apart and 10 mm(0.4 in) in from the outer edge of the disc.
Brake Dbc Thickn6s:
Standlrd: 20.9 - 21.8 mm (0.82 - 0.86 in)
Max. Refinishing Limit: 19.0 mm 10.75 inl
NOTE: Replace the brake disc if the smallest mea-
surement is less than the max. refinishinq limit.
Brake Disc Parallelism: 0.015 mm (0.fit06 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-
tion.
NOTE: See section 18 for brake disc reDlacement.
