-
Remove the rear brake disc.
-
Check the rear pulser for chipped or damaged teeth and replace if necessary.
-
Measure the air gap between the sensor and pulser all the way around while rotating the hub bearing unit by hand.
Specs:
Standard 0.4 - 1.0 mm (0.02 - 0.04 in)
NOTE: If the gap exceeds 1.0 mm (0.04 in) at any point, the probability is a distorted knuckle, which should be replaced.
