Escalade EXT AWD V8-6.2L (2009)
6. Install the remaining J-45101-100 - Conical Brake Rotor Washers and lug nuts onto the wheel studs and tighten the nuts firmly by hand in a
star-pattern.
7. Using the J-39544-KIT - Torque-Limiting Socket Set , or equivalent, tighten the lug nuts in a star-pattern to specification, in order to properly
secure the rotor. Refer to Tire and Wheel Removal and Installation (See: Maintenance/Wheels and Tires/Service and Repair).
8. If the brake rotor has been REFINISHED or REPLACED with a new rotor, proceed to step 14.
9. If the brake rotor meets the following criteria, proceed to step 10.
*
The rotor is within specifications and is being REUSED
*
The rotor has NOT been refinished
*
The rotor does NOT exhibit thickness variation exceeding the maximum allowable level
10. Mount a dial indicator, J-45101 - Hub
and Wheel Runout Gage , or equivalent, to the steering knuckle and position the indicator button so it contacts the brake rotor friction surface at a 90
degree angle, approximately 13 mm (0.5 in) from the outer edge of the rotor.
11. Measure and record the assembled LRO of the brake rotor.
1. Rotate the rotor until the lowest reading is displayed on the indicator dial, then set the dial to zero.
2. Rotate the rotor until the highest reading is displayed on the dial.
3. Mark the location of the high spot relative to the nearest wheel stud, or studs.
4. Measure and record the amount of LRO.
12. Compare the brake rotor assembled LRO to the following specifications:
Brake rotor maximum allowable assembled lateral runout: 0.05 mm (0.002 in)
Brake rotor maximum allowable assembled lateral runout: 0.13 mm (0.005 in)
13. If the brake rotor assembled LRO is within specifications, proceed to step 18.
