1. CHECKING THE HYDRAULIC UNIT ABS
OPERATION BY PRESSURE GAUGE
1) Lift-up the vehicle and remove the wheel.
2) Remove the air bleeder screws from FL and FR
caliper bodies.
3) Connect two pressure gauges to FL and FR cal-
iper bodies.
CAUTION:
•Use a pressure gauge used exclusively for
brake fluid measurement.
•Do not use the pressure gauge used for the
measurement of transmission oil. Doing so will
cause the piston seal to expand and deform.
NOTE:
Wrap sealing tape around the pressure gauge.
4) Bleed air from the pressure gauges and the FL
and FR caliper bodies.
5) Perform ABS sequence control.

6) When the hydraulic unit begins to work, first the
FL side performs decompression, hold and com-
pression, and then the FR side performs decom-
pression, hold and compression.
7) Read values indicated on the pressure gauge
and check if the fluctuation of the values between
decompression and compression meets the stan-
dard values. Depress the brake pedal and check
that the kick-back is normal, and tightness is nor-
mal.
8) Disconnect the pressure gauges from FL and FR
caliper bodies.
9) Install the air bleeder screws of FL and FR cali-
per bodies.
10) Remove the air bleeder screws from RL and
RR caliper bodies.
11) Connect two pressure gauges to RL and RR
caliper bodies.

5) Perform ABS sequence control.

6) When the hydraulic unit begins to work, check
the following work sequence.
(1) The FL wheel performs decompression,
hold and compression in sequence, and subse-
quently the FR wheel repeats the cycle.
(2) The RR wheel performs decompression,
hold and compression in sequence, and subse-
quently the RL wheel repeats the cycle.
7) Read values indicated on the brake tester and
check if the fluctuation of the values between de-
compression and compression meets specifica-
tion.
8) After the inspection, depress the brake pedal
and check that it is not abnormally hard, and tight-
ness is normal.
3. CHECKING THE HYDRAULIC UNIT VDC
OPERATION USING A PRESSURE GAUGE
1) Lift-up the vehicle and remove the wheel.

iper bodies.
CAUTION:
•Use a pressure gauge used exclusively for
