RELAY AWD V6-3.9L (2007)
Notice: Support the brake caliper with heavy mechanic 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.
6. Remove the caliper bracket bolts. Do not disconnect the brake flexible hose bolt.
Remove the brake caliper and the caliper mounting bracket as an assembly (1) from the suspension knuckle and support the assembly with heavy
mechanic's wire (2), or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose.
7. Matchmark the position of the brake rotor (1) to the wheel studs.
8. Remove the brake rotor (1).
Installation Procedure
Important: Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the
hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the
brake rotor, which could lead to brake pulsation.
1. Using the J 42450-A, thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange (2).
2. Using the J 41013, thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor (1).
3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
4. Install the brake rotor to the hub/axle flange. Use the matchmark made prior to removal for proper orientation to the flange.
5. If the brake rotor was removed and installed as part of a brake system repair, measure the assembled lateral runout (LRO) of the brake rotor to
ensure optimum performance of the disc brakes. Refer to Brake Rotor Assembled Lateral Runout Measurement. See: Testing and Inspection/Brake
Rotor Assembled Lateral Runout Measurement
