(b) Disconnect washer hose from nozzle.
(c) Press on the claw on the underside of the nozzle and remove it from above.
4. INSTALL WASHER NOZZLE For installation follow the removal procedure in reverse.
ADJUSTMENT OF WASHER NOZZLE
1. INSPECT WASHER NOZZLE
(a) While operating the washer, check whether the upper point where the washer fluid hits the windshield and the
up surge area are within the range indicated by the
hatched line.
(A) Approx. 150 mm (5.91 in.)
(B) Approx. 50 mm (1.99 in.)
(C) Approx. 0±1000 mm (0±3.94 in.)
(b) Check if the lower point where the washer fluid hits thewindshield is within the range of the wiping pattern (the
area of the glass which is wiped by the wiped blades.)
2. ADJUST WASHER NOZZLE Using a tool like that shown in the figure, change the direction
of the nozzle hole to adjust the point where washer fluid
strikes the windshield.

GENERAL DESCRIPTION
BR03E±06
1. Care must be taken to replace each part properly as it could affect the \
performance of the brakesystem and result in a driving hazard. Replace the parts with parts of the same part number or
equivalent.
2. It is very important to keep parts and the area clean when repairing the\
brake system.
3. If the vehicle is equipped with a mobile communication system, refer to the precaution \
in the IN section.
DESCRIPTION
BR03F±03
The service brakes consist of a foot brake which changes rotational energy to therma\
l energy to stop the
vehicle while it is being driven and a parking brake to keep the vehicle from m\
oving while it is parked.
OPERATION
FOOT BRAKE
BR03G±06
When the brake pedal is depressed, a vacuum builds up in the booster whi\
ch amplifies the pedal force,
pressing on the piston in the master cylinder. The piston movement raises the hydraulic pressure in the
cylinder. This hydraulic pressure is then applied to each respective brake cylin\
der, and acts to press the
brake pads against the rotating discs. The resulting friction converts the ro\
tational energy to thermal ener-
gy, stopping the vehicle.
