Brakes are grinding in the rear

Hi,

Replacing rear brake pads and rotors really isn't too hard. If you do it yourself, make sure to get lifetime parts so you won't have to pay for them again in the future. Also, you can expect rear brake pads to last approximately 30,000 miles. However, that varies based on driving habits and terrain.

To start, here is a link that shows in general how it is done. You can use this as a guide.

Next, here is a video showing it being done on a Dodge Nitro. Although it is a different vehicle, the procedure is similar.

Here are the directions specific to your vehicle for replacement. The pics below correlate with the directions.

REMOVAL

NOTE: Refer to Warnings and Cautions.

1. Raise and support the vehicle.

NOTE: Perform STEP 2 through STEP 7 on each side of the vehicle to complete pad set removal.

2. Remove the wheel mounting nuts (3), then the tire and wheel assembly (1).

NOTE: In some cases, it may be necessary to retract the caliper piston in its bore a small amount in order to provide sufficient clearance between the pads and the rotor to easily remove the caliper from the knuckle. This can usually be accomplished before the guide pin bolts are removed, by grasping the rear of the caliper and pulling outward working with the guide pins, thus retracting the piston. Never push on the piston directly as it may get damaged.

3. Remove the two caliper guide pin bolts (4).

4. Remove the caliper assembly (1) from the brake adapter by first rotating the top of the caliper away from the rotor (2), and then lifting the caliper assembly off the lower machined abutment (4) on the adapter.
5. Hang the brake caliper from rear strut using wire or cord to prevent the weight of the caliper from damaging the brake hose.

6. Remove the outboard brake pad from the caliper by prying the brake pad retaining clip (3) over the raised area on the caliper (1). Slide the brake pad off of the brake caliper.

7. Pull the inboard brake pad away from caliper piston until the retaining clip (1) is free from the cavity in the piston (2). Remove the pad.

Install is the reverse of removal.
