Brake Pedal Play Check
Pedal play should be within specification. If out of
specification, check brake light switch for proper
installation position and adjust if necessary.
Also check pedal shaft bolt and master cylinder pin
installation for looseness and replace if defective.
Brake pedal play "d"
: 1 – 8 mm (0.04 – 0.32 in.)
Brake Fluid Level Check
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 warning light lights sometimes during driving,
replenish fluid to MAX line.
When fluid decreases quickly, inspect brake system for
leakage. Correct leaky points and then refill to specified
level.
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.
Air Bleeding of Brake System
S6JB0A4106002
CAUTION
!
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 rake system.
Hydraulic lines of brake system are based on the
diagonal split system. When a brake pipe or hose was
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
IYSQ01410010-01
Perform bleeding operation starting with
wheel cylinder farthest from master cylinder
and then at front caliper of the same brake

line. Do the same on the other brake line.
1. Right brake caliper
2. Left brake caliper
3. Right wheel cylinder
1) Fill master cylinder reservoir with specified brake
fluid and keep at least one-half full of fluid during
bleeding operation.
2) Remove bleeder plug cap.
Attach a vinyl tube (1) to bleeder plug of wheel
cylinder, and insert the other end into container (2).
