1996 SUBARU LEGACY brake

7) Read values indicated on the brake tester and check if
the fluctuation of values, when decompressed and
compressed, meet the standard values.
Initial value When decompressed When compressed
Front wheel 1,961 N (200 kg, 441 lb) 245 N (25 kg, 55 lb) 1,961 N (200 kg, 441 lb)
Rear wheel 686 N (70 kg, 154 lb) 245 N (25 kg, 55 lb) 686 N (70 kg, 154 lb)

In case of hydraulic unit plunger piston malfunction:
Initial value When decompressed When compressed
Rear right wheel 686 N (70 kg, 154 lb) 245 N (25 kg, 55 lb) 686 N (70 kg, 154 lb)
Rear left wheel 686 N (70 kg, 154 lb) 686 N (70 kg, 154 lb) 686 N (70 kg, 154 lb)
8) After checking, also check if any irregular brake pedal
tightness is felt.
9) In case of AWD vehicles, remove the spare fuse from
the FWD connector in the engine compartment to return to
the original AWD state.
C: SEQUENCE CONTROL
Under the sequence control, after the hydraulic unit sole-
noid valve is driven, the operation of the hydraulic unit can
be checked by means of the brake tester or pressure
gauge.
B4M0082A
1. OPERATIONAL GUIDELINES OF THE SEQUENCE
CONTROL
1) Connect diagnosis terminals to 3 terminals (K) and 6
terminals (L) of the diagnosis connector beside driver seat
heater unit.
2) Set the speed of all wheels at 4 km/h (2 MPH) or less.
3) Within 0.5 seconds after the ABS warning lamp goes
out, immediately after the ignition switch is turned to on,
depress the brake pedal and hold.
CAUTION:
Do not depress the clutch pedal.
NOTE:

When the ignition switch is set to on, the brake pedal
must not be depressed.

Engine must not operate.

2. CONDITIONS FOR COMPLETION OF SEQUENCE
CONTROL
1) When the speed of at least one wheel reaches 10 km/h
(6 MPH), the operation is returned to the normal control
mode.
2) When L terminal is separated from ground, the opera-
tion is returned to the normal control mode.
3) When K terminal is separated from ground, the opera-
tion goes to the trouble code display mode.
4) When the brake pedal is released during sequence con-
trol and the braking lamp switch is set to off, the operation
is returned to the normal control mode.
5) After completion of the sequence control, the operation
is returned to the normal control mode.

SUPPLEMENTAL RESTRAINT SYSTEM“AIRBAG”
Airbag system wiring harness is routed near the center
brake pipe.
CAUTION:

All Airbag system wiring harness and connectors
are colored yellow. Do not use electrical test equip-
ment on these circuit.

Be careful not to damage Airbag system wiring har-
ness when servicing the center brake pipe.
A: REMOVAL AND INSTALLATION
CAUTION:

When removing and installing the brake pipe, make
sure that it is not bent.

After installing the brake pipe and hose, bleed the
