Checking The Hydraulic Unit Abs Operation With The Brake Tester
- Set wheels other than the one to measure on free rollers.
- Prepare for the ABS sequence control operation. < Refer to ABS SEQUENCE CONTROL . >
- Set the front wheels or rear wheels on the brake tester (a) and set the gear to neutral.
- Operate the brake tester.
- Perform ABS sequence control. < Refer to ABS SEQUENCE CONTROL . >
- When the hydraulic unit begins to work, check the following work sequence.
- The FL wheel performs decompression, hold and compression in sequence, and subsequently the FR wheel repeats the cycle.
- The RR wheel performs decompression, hold and compression in sequence, and subsequently the RL wheel repeats the cycle.
- Read values indicated on the brake tester and check if the fluctuation of the values between decompression and compression meets specification.
Inspection conditions Front wheel Rear wheel Initial value 1, 000 N (102 kgf, 225 lb) 1, 000 N (102 kgf, 225 lb) When depressurized 500 N (51 kgf, 112 lb) or less 500 N (51 kgf, 112 lb) or less When pressurized 1, 000 N (102 kgf, 225 lb) or more 1, 000 N (102 kgf, 225 lb) or more - After the inspection, depress the brake pedal and check that it is not abnormally hard, and tightness is normal.
