[hardywang]

此篇文章针对Pontiac Grand Prix，其他车型灵活运用。有些步骤，比如12、13是为了换上更大一号的刹车盘，不一定要效仿。

• Two 12" GM brackets, GM part # 18029829

• Two packages of dust boots, GM part #18024959

• Jack

• Jack stands (optional but HIGHLY recommended)

• Ratchet

• Torque wrench (with range up to 150 lb-ft)

• 13mm socket

• 14mm socket

• 15mm socket

• 19mm socket

• 19mm deep socket or 3/4" deep socket

• 13mm open-end wrench

• 14mm open-end wrench

• 15mm open-end wrench

• High temp grease

• Large C-clamp

• Wire shirt hanger or rope

• Electrical Tape (optional)

1. Starting with the installation of the front driver-side rotor, use a 19mm socket and break loose the 5 lugs on your wheel.

2. Set parking brake and then jack up the driver side front end until the wheel is a few inches off the ground. A jack stand is HIGHLY recommended to safely hold the front of the car up.

3. Finish loosen the 5 lugs and remove the wheel. Below you see the rotor and caliper.

4. You will need to remove the two caliper bolts and the two caliper bracket bolts. The picture below shows the bolts.

5. Using a 15mm socket, remove the two caliper bolts.

6. Grab the caliper from the back and pull forward on it, and then up and out.

7. Using a wire shirt hanger (will need to cut it with wire cutters) or a piece of rope, suspend the caliper out of the way by attaching it to the spring.

8. With the caliper out of the way, the brake pads are revealed. The brake pads(one in front and one in back) simply slide straight out of the metal clips.

9. You will need to carefully remove the four metal clips that hold the brake pads. These will be reused on the new 12" caliper bracket. They will come right off with a delicate "wiggle" up and out. Mark which clips went where (i.e. inside or outside, top or bottom).

10. Using a 15mm socket, remove the two caliper bracket bolts. The picture below on the left, points to the bottom bolt.

11. Now the rotor is free to remove straight out.

12. The next step is to prepare the new caliper bracket. To accommodate the larger front PowerSlot rotor, you will need two 12" GM brackets listed in the beginning. You can see in the two pictures below, the larger 12" bracket on the right. Thanks to Mike Napurano for the comparison pics.

13. You will also need to buy two packages of dust boots (each package contains 2 boots) to insert into the new 12" bracket. Using hi-temp brake grease, lube the rubber peg and insert it all the way into each of the holes in the bracket. Then using either a 19mm or 3/4" deep socket, firmly press the boots into the bracket holes. Lubing up the lip of each boot will help to push it in easier.

14. Slide the new PowerSlot rotor on, making sure you put the one labeled "L" on the driver side and the "R" on the passenger side. To help keep the rotor steady, you may want to tighten two lugs on opposite-end bolts ot hold the rotor steady.

15. Bolt the new 12" bracket back on. Torque bolts to 137 lb ft.

[hardywang]

16. Attach the metal clips to the new bracket and slide the brake pads on.

[hardywang]

17. Remove the caliper from the hanger or rope that you used, and using a large C-clamp and a piece of wood, compress the caliper piston until it is flush.

[hardywang]

18. Attach the caliper to the bracket, making sure that the dust boot is not pinched. Lube the caliper bolts with hi-temp brake grease, and torque the bolts to 63 lb ft.

19. Follow steps 1-3 in reverse order.
