Removal and InstallationINFOID:0000000001726771
Removal
1. Disconnect brake lines from dual proportioning valve.
Mark brake lines for installation.
2. Remove dual proportioning valve bolt and dual proportioning valve.
3. Remove two bolts and bracket.
Installation
Installation is in the reverse order of removal.
When installing brake lines to the dual proportioning valve, tighten to specifications. Refer to BR-14,
"Hydraulic Circuit".
InspectionINFOID:0000000001726772
CAUTION:
Carefully monitor brake fluid level at master cylinder.
Use the recommended new brake fluid. Refer to MA-19, "
Fluids and Lubricants".
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on paint areas, wash it away with water immediately.
1. Connect commercially available brake fluid pressure gauge to
air bleeders of front and rear brakes on either LH and RH side.
2. Bleed air from the Tool.
3. Check fluid pressure by depressing brake pedal.
Unit: kPa (kg/cm2, psi)
If output pressure is out of specification, replace dual proportioning valve.
4. Bleed air after disconnecting the Tool. Refer to BR-8, "
Bleeding Brake System". Applied pressure
(Front brake)7,355 (75, 1,067)
Output pressure
(Rear brake)5,099 - 5,492 (52 - 56, 740 - 796)

3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3
NO >> Replace the wheel sensor. Refer to BRC-83, "
Removal and Installation".
3.CHECK TIRES
Check for inflation pressure, wear and size of each tire.
Are tire pressure and size correct and is tire wear within specifications?
YES >> GO TO 4
NO >> Adjust tire pressure or replace tire(s).
4.CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FA X - 6 , "
On-Vehicle Inspection and Service" (front) or RAX-5,
"On-Vehicle Inspection and Service" (rear).
Is the inspection result normal?
YES >> GO TO 5
NO >> Repair or replace as necessary. Refer to FAX-7, "
Removal and Installation" (front) or RAX-6,
"Removal and Installation" (rear).
5.CHECK WIRING HARNESS FOR SHORT CIRCUIT
1. Disconnect ABS actuator and electric unit (control unit) connec-
tor and wheel sensor connector of malfunction code No.
2. Check continuity between wheel sensor harness connector ter-
minals and ground.
Is the inspection result normal?
YES >> GO TO 6
NO >> Repair the circuit.
6.CHECK WIRING HARNESS FOR OPEN CIRCUIT
1. Check continuity between ABS actuator and electric unit (control unit) harness connector E125 and the
malfunctioning wheel sensor harness connector E18, E117, C10, or C11.
Is the inspection result normal?
YES >> Replace the ABS actuator and electric unit (control unit). Refer to BRC-85, "Removal and Installa-
tion".
NO >> Repair the circuit.Continuity should not exist.
