Disc Runout Inspection
L
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.

Rear Brake Disc
Disc Runout Inspection
1.Loosen the front wheel nuts slightly, then raise thevehicle, and suppon it on safety stands. Removethe front wheels.
Remove the brake pads (see page 19-24).
Inspect the disc surface for damage and cracks.Clean the disc thoaoughly, and remove a

rust.
Use wheel nuts and suitable plain washers to holdthe disc securely against the hub. then mount a dialindicator as shown. and measure the runout at10 mm (0.4 in) from the outer edge of the disc.
Brake Disc Runout:
Service Limit:0.10 mm {0.00,t in)
5. lf the disc is beyond the service limit, refinish thebrake disc,
Max. Retinishing Limit: 8.0 mm {0.31 in)
NOTE: A new disc should be refinished if its runoutis greater than 0.10 mm (0.004 in).

Inspection
1. Loosen the front wheel nuts slightly, then raise thevehicle, and support it on safety stands. Removethe front wh6els.
2. Remove the brake pads (see page j9-24).
3. Using a micrometer. measure disc thickness aterght points, approximately 45" apart and 1o mm{0.4 in) in from the outer edge of the disc. Replacethe brake disc if the smallest measurement is lessthan the max. refinishing limit.
Brake Disc Thickness:
Standard: 8.9 - 9.1 mm (0.350 - 0.358 in)Max. Rsfinishing Limit: 8.0 mm {0.31 in}
Brake Disc Parallelirm: 0.015 mm(0.0006 inl msx.
