Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks around the front wheels.
Wear protective gloves and glasses.

2. Remove Rear Wheels

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts of the rear wheels slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the rear wheels.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench.
Remove the brake caliper by unscrewing the caliper bolts. Support the caliper with a bungee cord or wire to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper slides and lubricate them if necessary.
Install new brake pads in the caliper bracket, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Remove any retaining screws from the brake rotor, if applicable.
Slide off the old rotor and inspect the hub for corrosion or damage.
If replacing, install the new rotor onto the hub, ensuring it is flush against the surface.
Reinstall any retaining screws.

5. Reassemble Brake Components

Reinstall the brake caliper over the new brake pads.
Torque the caliper bolts to the manufacturer's specifications (check service manual for exact torque values).
Reinstall the rear wheels and torque the lug nuts in a star pattern to the specified torque.

6. Final Checks

Lower the vehicle and remove wheel chocks.
Pump the brake pedal several times to ensure proper brake pad contact with the rotor.
Test drive the vehicle at low speed to confirm the grinding noise is resolved.
