Legacy GT Wagon AWD F4-2.5L DOHC (1997)
8) Remove pressure gauges and air bleeder screws from the RL and RR caliper bodies.
9) Connect the air bleeder screws hose to the FL and FR caliper bodies.
10) Connect two pressure gauges to the RL and RR caliper bodies.
11) Bleed air from the pressure gauges and the FL and FR caliper bodies.
12) Perform ABS sequence control.
13) When the hydraulic unit begins to work, at first the RR side performs decompression, holding, and compression, and then the RL side performs
decompression, holding, and compression.
14) Read values indicated on the pressure gauges and check if they meet the standard value.
15) After checking, remove the pressure gauges from caliper bodies.
16) Connect the air bleeder screws to RL and RR caliper bodies.
17) Bleed air from brake line.
Checking The Hydraulic Unit ABS Operation With Brake Tester
1) Prepare for operating ABS sequence control.
2) Set the front wheels or rear wheels on the brake tester and set the select lever's position at "neutral".
3) Operate the brake tester.
4) Perform ABS sequence control.
5) Hydraulic unit begins to work; and check the following working sequence.
(1) The front left wheel performs decompression, holding, and compression in sequence, and subsequently the front right wheel repeats the
cycle.
(2) The rear right wheel performs decompression, holding, and compression in sequence, and subsequently the rear left wheel repeats the
cycle.
6) Read values indicated on the brake tester and check if the fluctuation of values, when decompressed and compressed, meet the standard values.
7) After checking, also check if any irregular brake pedal tightness is felt.
ABS Sequence Control
ABS SEQUENCE CONTROL
1) Under the ABS sequence control, after the hydraulic unit solenoid valve is driven, the operation of the hydraulic unit can be checked by means of
the brake tester or pressure gauge.
2) ABS sequence control can be started by diagnosis connector or select monitor.
