Checking The Hydraulic Unit Abs Operation With The Brake Tester

WARNING: This page is about a different car, the 2011 Subaru Tribeca. However, it is still accessible from the selected car via links, so may be relevant.

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 and set the select lever position to the "N" range.

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.
1. The FL wheel performs decompression, hold and compression in sequence, and subsequently the FR wheel repeats the cycle.
2. 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.

PRESSURE SPECIFICATION

	Front wheel	Rear wheel
Initial value	2, 000 N (204 kgf, 450 lb)	2, 000 N (204 kgf, 450 lb)
When depressurized	500 N (51 kgf, 112 lb) or less	500 N (51 kgf, 112 lb) or less
When pressurized	2, 000 N (204 kgf, 450 lb) or more	2, 000 N (204 kgf, 450 lb) or more

After the inspection, depress the brake pedal and check that it is not abnormally hard, and tightness is normal.
