FRONT AND REAR BRAKES
CAUTION:
_
Do not remove the hydraulic unit to check
the resistance of the solenoid valves and
the ABS motor for continuity.
WARNING
_
Refill with the same type of brake fluid that
is already in the system. Mixing fluids may
result in a harmful chemical reaction, lead-
ing to poor braking performance.
CAUTION:
_
• Handle the ABS components with care
since they have been accurately adjusted.
Keep them away from dirt and do not sub-
ject them to shocks.
• The ABS wheel sensor cannot be disas-
sembled. Do not attempt to disassemble
it. If faulty, replace with a new one.
• Do not set the main switch to "ON" when
removing the hydraulic unit.
• Do not clean with compressed air.
• Do not reuse the brake fluid.
• Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
• Do not allow any brake fluid to contact
the couplers. Brake fluid may damage the
couplers and cause bad contacts.
• If the union bolts for the hydraulic unit
have been removed, be sure to tighten
them to the specified torque and bleed
the brake system.
