BRAKE TUBE AND HOSEPFP:46210
Hydraulic CircuitBFS000FY
CAUTION:

All brake tubes and hoses must be free from excessive bending, twisting and pulling.

Make sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.

Brake tubes and hoses is an important safety part. If a brake fluid leak is detected, always disas-
semble the parts. Replace applicable part with a new one, if necessary.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe off them and wash it away with water
immediately.

Do not bend or twist brake hose sharply, or strongly pull it.

When removing components, cover brake line connections so that no dirt, no dust, or other for-
eign matter gets in.

Refill with new brake fluid “DOT 3 or DOT4”.

Do not reuse drained brake fluid.

SYSTEM DESCRIPTIONPFP:00000
System DiagramBFS000CO
FunctionsBFS000CP
ABS

The Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.

If the electrical system breaks down, then the fail-safe function is activated, ABS becomes inoperative,
and ABS warning lamp turns on.

Electrical system diagnosis by CONSULT-II is available.

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

COMPONENTS
REMOVAL
Be careful of the following:
CAUTION:
When removing the wheel sensor, do not rotate it if possible, and do not forcibly pull the wheel sensor
harness.
INSTALLATION
Note the following, and tighten bolts to the specified torque.

Check the inside of the wheel sensor mounting hole for foreign materials, the rotor surface for iron chips
and other foreign materials. Clean both the wheel sensor mounting hole and the rotor surface before
installation. Replace the wheel sensor if there is any non-standard condition.

Completely push in rubber clamp of strut bracket and body bracket until they lock when installing front
wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto bracket
with yellow line on the harness facing bracket opening (mounting hole). There should be no twists in the
harness when installed.

When installing the rear sensor, securely install the harness mount of the rear suspension member so that
the wheel sensor harness is not twisted. In addition, there should be no twists in the harness when
installed.
