5B-2 FRONT BRAKE
GENERAL DESCRIPTION
DISC BRAKE CALIPER ASSEMBLY
This caliper is mounted to the brake caliper carrier with two caliper pin bolts. Hydraulic force, created by applying
force to the brake pedal, is converted by the caliper to friction. The hydraulic force acts equally against the piston
and the bottom of the caliper bore to move the piston outward and to move (slide) the caliper inward, resulting in
a clamping action on the disc. This clamping action forces the pads (linings against the disc, creating friction to
stop the vehicle.
NOTE:

Lubricate parts as specified. Do not use lubricated shop air on brake parts as damage to rubber compo-
nents may result. If any component is removed or line disconnected, bleed the brake system.
Replace pads in axle sets only. The torque values specified are for dry, unlubricated fasteners.

For identification of the brake caliper type, see maker name or mark on brake caliper as shown.

Brake Disc
Before this inspection, brake pads must be removed.
Check disc surface for scratches in wearing parts. Scratches on
disc surface noticed at the time of specified inspection or replace-
ment are normal and disc is not defective unless they are serious.
But when there are deep scratches or scratches all over disc sur-
face, replace it. When only one side is scratched, polish and correct
that side.
Disc thickness ªaº
Standard: 22 mm (0.866 in.) For SUMITOMO ELECTRIC. . . . .
brake caliper
17 mm (0.670 in.) For TOKICO brake caliper. . . . .
Service limit: 20 mm (0.787 in.) For SUMITOMO ELECTRIC. .
brake caliper
15 mm (0.590 in.) For TOKICO brake caliper. .
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 25 mm (0.98 in.) from the outer edge of the disc.
Limit on disc deflection: 0.15 mm (0.006 in.)
NOTE:
Check front wheel bearing for looseness before measure-
ment.
Cylinder Slide Guide Pin / Pin Bolt
Check guide pin for smooth movement as shown.
If it is found faulty, correct or replace. Apply rubber grease to guide
pin outer surface. Rubber grease should be the on whose viscosity
is less affected by such low temperature a ±40
C (±40
F).
Dust Boot
Check boot for breakage, crack and damage. If defective, replace.

Cracked, Scored, or Grooved Drum
A cracked, drum is unsafe for further service and must be replaced.
Do not attempt to weld a cracked drum.
Smooth up any slight scores. Heavy or extensive scoring will cause
excessive brake lining wear and it will probably be necessary to re-
surface drum braking surface.
If brake linings are slightly worn and drum is grooved, drum should
be polished with fine emery cloth but should no be turned.
NOTE:
When drum is removed, visually inspect wheel cylinder for
brake fluid leakage. Correct leaky point, if any.
Brake Shoe
Where lining is worn out beyond service limit, replace shoe.
Thickness ªaº
Standard: 6.5 mm (0.24 in.)
Service limit: 3.0 mm (0.12 in.)
If one of brake linings is to service limit, all linings must be replaced
at the same time.
CAUTION:
Never polish lining with sandpaper. If lining is polished with
sandpaper, hard particles of sandpaper will be deposited in
lining and may damage drum. When it is required to correct
lining, replace it with a new one.
INSTALLATION
NOTE:
See NOTE at the beginning of the section.
1) Before installing brake drum, check outer diameter of brake
shoes. If it is not within value as specified below, adjust it to spec-
ification by turning adjuster.
Outer diameter of brake shoes
ªaº: 219.4 ± 219.7 mm (8.638 ± 8.650 in.)

7C1-2 CLUTCH
The clutch is a diaphragm-spring clutch of a dry single
disc type. The diaphragm spring is of a tapering-finger
type, which is a solid ring in the outer diameter part,
with a series of tapered fingers pointing inward.
The disc, carrying torsional coil springs, is positioned
on the transmission input shaft with an involute spline
fit.
The clutch cover is secured to the flywheel, and car-
ries the diaphragm spring in such a way that the pe-
ripheral edge part of the spring pushes on the pres-
sure plate against the flywheel (with the disc in be-
tween), when the clutch release bearing is held back.
This is the engaged condition of the clutch.Depressing the clutch pedal causes the release bear-
ing to advance and pushes on the tips of the tapered
fingers of the diaphragm spring. When this happens,
the diaphragm spring pulls the pressure plate away
from the flywheel, thereby interrupting the flow of
drive from flywheel through clutch disc to transmis-
sion input shaft.
