4.
Remove the two bolts that attach the front brake caliper mounting brackets to the knuckle.
Notice:
Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake
hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which
may cause damage to the brake hose and in turn may cause a brake fluid leak.
5.
Remove the brake caliper and bracket as an assembly and support it with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic
brake flexible hose from the caliper.
6.
Mark the relationship of the rotor to the bearing hub.
7.
If equipped, remove the rotor retaining push nuts from the wheel studs.
8.
Remove the rotor.
9.
Remove the bolt (1) that attaches the wheel speed sensor to the bearing hub.
Notice:
Carefully remove the sensor by pulling it straight out of the bore. DO NOT use a screwdriver or other device to try to pry the sensor out of the
bore. Prying will cause the sensor body to break off in the bore.
10.
Remove the wheel speed sensor from the bearing hub assembly.
Important:
The mounting surface on the sensor must be flat in the next step in order to be mounted correctly on the bearing hub assembly. If the mounting
surface on the sensor is warped or bent, the sensor must be replaced.
11.
Inspect to see if the mounting surface on the sensor is flat. Check the mounting surface on the sensor head for flatness by placing it on the edge of
a metal machinist's scale or other suitable straight edge to measure the flatness. Check the sensor for flatness in multiple positions/directions
(minimum 3).
