General Description
Brakes ConstructionS7RS0B4101001
When the foot brake pedal is depressed, hydraulic pressure is developed in the master cylinder to actuate pistons (two
in front and two in rear).
The master cylinder is a tandem master cylinder. Brake pipes are connected to the master cylinder and they make two
independent circuits. One connects front right & rear left brakes and the other connects front left & rear right brakes.
In this brake system, the disc brake type is used for the front wheel brake and the rear wheel brake.
The parking brake system is mechanical. It applies brake force to only rear wheels by means of the cable and
mechanical linkage system. The same brake shoes or pads are used for both parking and foot brakes.

If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol out
of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake
mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
system.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.

Section 2D”.
2) Remove caliper pin bolts (1). 3) Remove caliper (1) from caliper carrier (2).
NOTE
Hang removed caliper (1) with a wire hook (4)
or the like so as to prevent brake hose from
bending and twisting excessively or being
pulled.
Don’t operate brake pedal with brake pads
removed.
4) Remove brake pads (3).
5) Remove brake pad spring (1) as shown in figure.

Front Disc Brake Pad InspectionS7RS0B4206004
Check pad lining for wear. When wear exceeds limit,
replace with new one.
CAUTION!
Never polish pad lining with sandpaper. If
lining is polished with sandpaper, hard
particles of sandpaper will be deposited in
lining and may damage disc. When pad lining
requires correction, replace it with a new one.
Front brake pad thickness (lining thickness)
Standard: 10 mm (0.40 in.)
Limit: 2 mm (0.08 in.)

from damage. It should be taken out
gradually with moderately compressed air.
Do not place your fingers in front of piston
when using compressed air.
2) Remove cylinder boot.
