ABS (ABS : FULL AIR) BR03–13
INSPECTION (FRONT WHEEL BRAKE)
EN0680203H300001
1. INSPECTION OF ONLY WHEEL SENSOR
(1) With a tester, measure the resistance of wheel sensor.
Standard: 900-2,000

(2) When the measured value is out of the basic standard, change the
wheel sensor as it might be considered presumably to be abnormal.
2. INSPECTION OF THE SENSOR RING.
(1) Make a visual inspection to check for damage or deformation of the
sensor ring, and also to make sure it is not coming loose from the
wheel hub.
(2) If any damage or malformation is discovered, replace the sensor ring.
(3) If the sensor ring is coming loose from the wheel hub, use a dolly
block and press it in with a press again.
3. INSPECTION OF THE CLAMPING BUSHING.
(1) Make sure that wheel sensor is securely fixed.
(2) Change the clamping bushing when it can be pulled off or pushed in
with a weak force.
4. MOUNTING THE SENSOR RING
(1) Place the sensor ring on the wheel hub and use the dolly block and a
press to evenly pressure mount it.
NOTICE
Warming up the sensor ring with hot water will make it easier to pres-
sure mount it. Do not use a gas burner or the like to warm the sensor
ring. Doing so could cause malformation of the sensor ring.
(2) After pressure mounting it, check for flutter of the sensor ring in the
axle direction.
Assembly standard: Less than 0.2 mm {0.0078 in.}
