A: INSPECTION
1) Install the oil pressure gauges to measure the master
cylinder fluid pressure (front wheel brake fluid pressure)
and rear wheel cylinder fluid pressure.
2) Bleed air from the oil pressure gauges.
3) Check the master cylinder fluid pressure and rear wheel
cylinder fluid pressure.
The standard values are shown in Figure.
4) For the oil pressure in case of split point, refer to A:
SPECIFICATIONS 4-4 [S0A0].
B: REMOVAL
1) Remove brake pipe from proportioning valve at four
places.
2) Remove proportioning valve from its bracket.
CAUTION:
Do not disassemble or adjust the proportioning valve.
(The proportioning valve must be replaced as an
assembly.)
C: INSTALLATION
1) Install proportioning valve to bracket.
2) Connect brake pipes correctly to proportioning valve.
3) Bleed air, then check each joint of brake pipe for oil
leaks.

2) Measure ABS sensor resistance.
ABS sensor Terminal No. Standard
Front - LH 1 and 2
1.0±0.2 kΩ Front - RH 1 and 2
Rear - LH 1 and 2
Rear - RH 1 and 2
CAUTION:
If resistance is outside the standard value, replace
ABS sensor with new one.
NOTE:
Check ABS sensor cable for discontinuity. If necessary,
replace with a new one.
G4M0448
2. TONE WHEEL
1) Check tone wheel’s teeth (44 pieces) for cracks or
dents. If necessary, replace tone wheel with a new one.
2) Clearances (sensor gaps) should be measured one by
one to ensure tone wheel and speed sensor are installed
correctly.
ABS sensor clearance:
Front
0.9—1.4 mm (0.035—0.055 in)
Rear
0.7—1.2 mm (0.028—0.047 in)
NOTE:
If clearance is narrow, adjust by using spacer (Part No.
26755AA000).
If clearance is wide, check the outputted voltage then
replace ABS sensor or tone wheel if the outputted voltage
is outside the specification.

3. OUTPUT VOLTAGE
Output voltage can be checked by the following method.
Install resistor and condenser, then rotate wheel about 2.75
km/h (2 MPH) or equivalent.
NOTE:
Regarding terminal No., please refer to item 1. ABS SEN-
SOR.
C: INSTALLATION
1. FRONT ABS SENSOR
1) Install tone wheel on hub, then install housing on hub
assembly.
G4M0443
2) Temporarily install front ABS sensor on housing.
CAUTION:
