FRONT AND REAR BRAKES
• When refilling, be careful that water does
not enter the brake fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor
lock.
CAUTION:
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
4. Bleed:
• brake system
Refer to "BLEEDING THE HYDRAULIC
BRAKE SYSTEM" in chapter 3.
5. Check:
• brake fluid level
Below the minimum level mark
the recommended brake fluid to the proper
level.
Refer to "CHECKING THE BRAKE FLUID
LEVEL" in chapter 3.
6. Check:
• brake pedal operation
WARNING
A soft or spongy feeling in the brake pedal
can indicate the presence of air in the brake
system. Before the vehicle is operated, the
air must be removed by bleeding the brake
system. Air in the brake system will consid-
erably reduce braking performance and
could result in loss of control and possibly
an accident. Therefore, check and, if neces-
sary, bleed the brake system.
7. Adjust:
• brake pedal position
Refer to "ADJUSTING THE REAR BRAKE"
in chapter 3.
