| Operation and Leakage
Check |
Check all of the following
items:
Component
|
Procedure
|
Brake Booster (A)
|
Check brake operation by applying the brakes during a
test drive. If the brakes do not work properly, check the brake
booster. Replace the brake booster as an assembly if it does not
work properly or if there are signs of leakage.
|
Piston cup and pressure cup inspection
(B)
|
| •
|
Check brake operation by applying the
brakes. Look for damage or signs of fluid leakage. Replace the
master cylinder as an assembly if the pedal does not work
properly or if there is damage or signs of fluid
leakage. |
| •
|
Check for a difference in brake pedal
stroke between quick and slow brake applications. Replace the
master cylinder if there is a difference in pedal
stroke. | |
Brake hoses (C)
|
Look for damage or signs of fluid leakage. Replace the
brake hose with a new one if it is damaged or
leaking.
|
Caliper piston seal and piston boots (D)
|
Check brake operation by applying the
brakes.
Look for damage or signs of
fluid leakage. If the pedal does not work properly, the brakes drag,
or there is damage or signs of fluid leakage, disassemble and
inspect the brake caliper. Replace the boots and seals with new ones
whenever the brake caliper is
disassembled.

BRAKE
SYSTEM BLEEDING
| •
|
Do not reuse the drained
fluid. |
| •
|
Always use genuine DOT3/DOT4 brake
Fluid.
Using a non-genuine DOT3/DOT4 brake
fluid can cause corrosion and decrease the life of the
system. |
| •
|
Make sure no dirt of other foreign
matter is allowed to contaminate the brake
fluid. |
| •
|
Do not spill brake fluid on the
vehicle, it may damage the paint; if brake fluid does contact
the paint, wash it off immediately with
water. |
| •
|
The reservoir on the master cylinder
must be at the MAX (upper) level mark at the start of bleeding
procedure and checked after bleeding each brake caliper. Add
fluid as
required. | |
| 1. |
Make sure the brake fluid in the reservoir
is at the MAX (upper) level line. |
| 2. |
Have someone slowly pump the brake pedal
several times, and then apply
pressure. |
| 3. |
Loosen the right-rear brake bleed screw (A)
to allow air to escape from the system. Then tighten the bleed screw
securely.
|
| 4. |
Repeat the procedure for wheel in the
sequence shown below unit air bubbles no longer appear in the
fluid.
|
| 5. |
Refill the master cylinder reservoir to MAX
(upper) level
line. |
