Replacing the Rear Brake Pads

-
2

3
Apply brake system cleaner over the brake components. Wipe off the sprayed areas with a rag. Start with the brakes on one wheel, while using the other as a reference.
-
4
Remove the caliper mounting bolts with a box wrench, while securing the guide pins with an open-end wrench from rotating.
-
5
Remove the caliper from the brake pads, and hang it from the shock absorber with a length of wire.
-
6
Pull out the brake pads from the caliper mounting bracket.
-
7

Do not attempt to blow brake dust, in any manner. Brake material is made with asbestos, which is dangerous to your health. Only use brake system cleaner.
