REMOVAL
1) Raise and suitably support vehicle. Remove tire and wheel.
This operation is not necessary when removing pipes connecting master cylinder and flexible hose.
2) Clean dirt and foreign material from both hose end or pipe end fittings. Remove brake hose or pipe.
INSTALLATION
1) Reverse removal procedure for brake hose and pipe installation procedure.
For installation, make sure that steering wheel is in straightforward position and hose has no twist or kink. Check
to make sure that hose doesn't contact any part of suspension, both in extreme right and extreme left turn condi-
tions. If it does at any point, remove and correct. Fill and maintain brake fluid level in reservoir. Bleed brake sys-
tem.
2) Perform brake test and check installed part for fluid leakage.

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.

2) Remove piston seal using a thin blade like a thickness gauge,
etc.
CAUTION:
Be careful not to damage inside (bore side) of cylinder.
INSPECTION
Cylinder Boot
Check boots for breakage, crack and damage. If defective, replace.
Piston Seal
Excessive or uneven wear of pad lining may indicate unsmooth re-
turn of the piston. In such a case, replace rubber seal.
ASSEMBLY
Reassemble front brake in reverse order of disassembly, noting the
following points.
CAUTION:

Wash each part cleanly before installation in the same
fluid as the one used in master cylinder reservoir.

Never use other fluid or thinner.

Before installing piston and piston seal to cylinder, apply
fluid to them.

After reassembling brake lines, bleed air from them.
Piston Seal
Piston seal is used to seal piston and cylinder and to adjust clear-
ance between pad and disc. Replace with a new one at every over-
haul. Fit piston seal into groove in cylinder taking care not to twist
it.

Caliper
Before installing caliper (cylinder body) to carrier, check to ensure
that guide pin (pin bolt) inserted in each caliper carrier hole can be
moved smoothly in thrust direction.
NOTE:
Where temperature gets as low as ±30
C in cold weather, use
rubber grease whose viscosity varies very little even at ±40
C
(±40
F).

5C-2 PARKING AND REAR BRAKE
GENERAL DESCRIPTION
DRUM BRAKE ASSEMBLY
The drum brake assembly has a self shoe clearance adjusting system so that drum-to-shoe clearance is main-
tained appropriate at all times. Rear brake is a drum type. It uses leading trailing operation when brake pedal is
depressed and when parking brake is applied on level road.
It also uses duo servo operation when parking brake is applied on gradient road and load is applied in longitudinal
direction of vehicle.
NOTE:
Replace all components included in repair kits to service this drum brake. Lubricate parts as specified.
WARNING:
If any hydraulic component is removed or brake line disconnected, bleed the brake system. The torque
values specified are for dry, unlubricated fasteners.
