@. Never use an air hose or dry brush to clgan brake
assemblies.
. Use an OsHA-approved vacuum cleanor lo avoid
breathing broke dust.
Inspection and Replacement (cont'dl
1. Loosen the front wheel nuts slightly. then raise the
vehicle, and support it on safety stands. Remove
the front wheels.
2. Remove the brake hose bracket from the knuckle.
3. Remove the caliper bolt B, and pivot the caliper up
out of the wav,

5. Using vernier calipers. measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thicknsss:
Standard; 8.5 - 9.5 mm 10.33 - 0.37 in)
Servica Limh: 1.6 mm {0.06 in}
lf the brake pad thickness is less than the service
limit, replace the front pads as a set,
Clean the caliper thoroughly; remove any rust. and
check for grooves and cracks.
Check the brake disc for damage and cracks,

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:

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.

Front Brake Caliper
It
Disassembly
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.
5410 Type:
NOTE: For 2056 type disassembly procedures, see page
19-14.
@o Never use an air hose ot dry brush to clean brakg
assemblies.
. Use an OSHA approved vacuum clganer to avoid
breathing brake dust.
CAUTION:
. Do not spill brake lluid on the vehicls; it may damage
the paint; if brake fluid does conlact the paint, wash
it off immedistely with waier.
. To prevenl spills, covet the hose ioin$ with rags or
shop towels.
. Clean all parts in brake fluid and air dry; blow out all
passages with compressed air.
