G6 V6-3.9L (2009)
Tighten the bolt to 50 Nm (37 lb ft).
6. Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding (Manual) (See: Brake Bleeding/Service and Repair)Hydraulic
Brake System Bleeding (Pressure) (See: Brake Bleeding/Service and Repair).
7. Remove the wheel nuts retaining the brake rotor to the wheel hub.
8. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (See: Maintenance/Wheels and Tires/Service and Repair).
9. Lower the vehicle.
10. With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
11. Slowly release the brake pedal.
12. Wait 15 seconds, then repeat steps 10 and 11 until a firm brake pedal is obtained. This will properly seat the brake caliper piston and brake pads.

Removal Procedure
Warning: Refer to Brake Fluid Irritant Warning (See: Service Precautions/Technician Safety Information/Brake Fluid Irritant Warning).
Caution: Refer to Brake Fluid Effects on Paint and Electrical Components Caution (See: Service Precautions/Vehicle Damage Warnings).
1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the
reservoir before proceeding.
3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the
midway point before proceeding.
4. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle (See: Maintenance/Vehicle Lifting/Service and Repair).
5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (See: Maintenance/Wheels and Tires/Service and Repair
).
6. Install a large C-clamp over the body of the brake caliper with the C-clamp ends against the rear of the caliper body and against the outer brake
pad.
Caution: When using a large C-clamp to compress a caliper piston into a caliper bore of a caliper equipped with an integral park brake
mechanism, do not exceed more than 1 mm (0.039 in) of piston travel. Exceeding this amount of piston travel will cause damage to the internal
adjusting mechanism and/or the integral park brake mechanism.
7. Tighten the C-clamp until the caliper piston is compressed into the caliper bore enough to allow the caliper to slide past the brake rotor.
Do not exceed 1 mm (0.039 in) of caliper piston travel.
8. Remove the C-clamp from the caliper.
