Front brakes locking up and grinding

Hi,

Replacing rear brake pads and rotors really isn't that difficult. When you do it yourself, make sure to get lifetime replacement parts so you never have to pay again. You can expect rear brakes to last approximately 30,000, but that will vary based on terrain and driving habits.

First, here is a link and videos that shows in general how it's done. You can use this as a guide.

Warning: Refer to Brake Dust Warning (See: Brakes and Traction Control > Technician Safety Information > Brake Dust Warning).

Removal Procedure

1. Inspect the fluid level in the brake master cylinder reservoir.
2. If the fluid level is midway between the maximum-full point and the minimum allowable level, no fluid needs to be removed from the reservoir before proceeding.
3. If the fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove fluid to the midway point before proceeding.
4. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle (See: Vehicle Lifting > Procedures > Lifting and Jacking the Vehicle).
5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (See: Wheels and Tires > Removal and Replacement > Tire and Wheel Removal and Installation).

Note:
* DO NOT use any air tools to remove the guide pin bolts. Use hand tools only.
* Install an open end wrench to hold the caliper guide pin in line with the brake caliper while removing or installing the caliper guide pin bolt. DO NOT allow the open end wrench to come in contact with the brake caliper. Allowing the open end wrench to come in contact with the brake caliper will cause a pulsation when the brake are applied.

7. Using an open end wrench to hold the guide pin, loosen the guide pin bolt.

8. Remove the guide pin bolt (1) from the brake caliper (2).

Caution: 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.

Note: Do not disconnect the hydraulic brake flexible hose from the brake caliper.

9. Rotate the brake caliper (2) upward until it stops on the caliper mounting bracket (5) and support the caliper with heavy mechanics wire or equivalent.

Note:
* If installing the original brake pads and spring clips, mark the position of the brake pads and spring clips for proper installation.
* If installing new brake pads, install new pad spring clips. Do not reuse the old pad spring clips with new brake pads.

10. Remove the brake pads (3) and spring clips (4) from the mounting bracket (5).
11. Thoroughly clean the pad hardware mating surfaces of the caliper bracket of any corrosion or debris with denatured alcohol and allow to dry.

Note: Use care when cleaning the brake caliper pistons to avoid damaging the piston dust seals.

12. If installing new brake pads, thoroughly clean the brake caliper piston faces and caliper housing to brake pad contact surfaces of all disc brake pad insulator adhesive residue with denatured alcohol and allow to dry.

Installation Procedure

1. Apply a very thin coating of high temperature silicone brake lubricant to the pad hardware mating surfaces of the caliper bracket only.
2. Install the spring clips (4) on the caliper mounting bracket (5).
3. If installing new brake pads, remove the adhesive backing paper from the disc brake pad insulators.

Note: If installing the original brake pads, note the locations marked prior to removal.

4. Install the brake pads (3).
5. Remove the mechanics wire and rotate the brake caliper (2) into position on the mounting bracket (5).
6. Install NEW caliper guide pin bolts.

Caution: Refer to Fastener Caution (See: Vehicle > Vehicle Damage Warnings > Fastener Caution).

Note:
* DO NOT use any air tools to remove or tighten the guide pin bolts. Use hand tools ONLY.
* Install an open end wrench to hold the caliper guide pins in line with the caliper while removing or installing the caliper. DO NOT allow the wrench to come in contact with the brake caliper. Allowing the wrench to come in contact with the brake caliper will cause a pulsation when the brakes are applied.

7. Use a open end wrench to hold the caliper guide pin while tightening the guide pin bolt to 38 Nm (28 lb ft).
8. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (See: Wheels and Tires > Removal and Replacement > Tire and Wheel Removal and Installation).
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 10-11 until a firm pedal is obtained, to properly seat the brake caliper pistons and brake pads.
13. Fill the brake master cylinder reservoir to the proper level with clean brake fluid. Refer to Master Cylinder Reservoir Filling (See: Brake Master Cylinder > Procedures > Master Cylinder Reservoir Filling).
14. Firmly apply and maintain pressure on the brake pedal for 30 seconds to seat the brake pad insulators to the brake caliper pistons and caliper housing. Repeat this step 1 additional time.
15. Burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing (See: Brake Pad > Procedures > Brake Pad and Rotor Burnishing).

17. Remove the brake rotor from the axle flange.

Installation Procedure

Note: 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 - Wheel Hub Resurfacing Kit, clean the rust and contaminants from the mating surface of the hub flange.
2. Using the J-41013 - Rotor Resurfacing Kit, clean all rust and contaminants from the inside diameter of the hat section of the brake rotor to prevent any foreign material from getting between the brake rotor and the hub flange.
