Brake Fluid Level Inspection

CAUTION
!
Do not use shock absorber fluid or any other
fluid which contains mineral oil. Do not use a
container which has been used for mineral oil
or a container which is wet from water.
Mineral oil will cause swelling and distortion
of rubber parts in hydraulic brake system and
water mixed into brake fluid will lower fluid
boiling point. Keep all fluid containers
capped to prevent contamination.
NOTE
Be sure to use particular brake fluid either as
indicated on reservoir cap of that vehicle or
recommended in owner's manual which
comes along with that vehicle. Use of any
other fluid is strictly prohibited.
Fluid level should be between MIN and MAX
lines marked on reservoir.
When brake warning light lights sometimes
during driving, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake
system for leakage. Correct leaky points and
then refill to specified level.
1) Check master cylinder, reservoir and reservoir hose
(if equipped) for crack, damage and brake fluid
leakage. If any faulty condition exists, correct or
replace.
2) Check that brake fluid level is between MAX (1) and
MIN marks (2) on reservoir.

Brake Fluid Replacement

Change brake fluid as follows.
Drain existing fluid from brake system completely, fill
system with specified fluid and carry out air purge
operation.
For air purge procedure refer to "Air Bleeding of Brake
System".

Brake Light Switch Adjustment

S6RW0C4106004
Adjustment should be made as follows. Pull up brake
pedal toward you and while holding it there, adjust
switch position so that clearance between end of thread
and brake pedal is as specified. Then lock it by turning
clockwise.
Clearance between brake pedal and brake light
switch
"a": 0.5 – 1.5 mm (0.02 – 0.05 in.)

Air Bleeding of Brake System

Brake fluid is extremely damaging to paint. If
fluid should accidentally touch painted
surface, immediately wipe fluid from paint
and clean painted surface.
Bleeding operation is necessary to remove air whenever
it entered hydraulic brake system.
Hydraulic lines of brake system are based on the
diagonal split system. When a brake pipe or hose was
2 disconnected at the wheel, bleeding operation must be
performed at both ends of the line of the removed pipe or
hose. When any joint part of the master cylinder of other
joint part between the master cylinder and each brake
(wheel) was removed, the hydraulic brake system must
be bled at all 4 wheel brakes.
NOTE
Perform bleeding operation starting with rear
brake caliper or wheel cylinder farthest from
I7RW01410004-01
master cylinder and then at front caliper of
the same brake line. Do the same on the
other brake line.
