Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

Tools Required: Socket set, torque wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, lug wrench
Sub-steps:
1. Remove the brake caliper by unscrewing the mounting bolts.
2. Carefully slide the caliper off the rotor and support it using a bungee cord (do not let it hang from the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper bracket for wear; clean it if necessary.
5. Install new brake pads, ensuring they are seated properly in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if needed), torque wrench
Sub-steps:
1. If the rotors are damaged or worn, remove them by unscrewing the retaining screws (if equipped) and sliding them off the hub.
2. Install new rotors, ensuring they are free of oil or debris.
3. Secure the rotors, ensuring they are aligned correctly.

5. Reassemble Braking Components

Tools Required: Torque wrench
Sub-steps:
1. Reattach the brake caliper over the new brake pads.
2. Tighten caliper mounting bolts to manufacturer specifications (typically around 25-35 Nm).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and then torque the lug nuts to the specified value (typically around 100-120 Nm).

6. Final Checks

Tools Required: None
Sub-steps:
1. Reconnect the battery.
2. Pump the brake pedal several times to seat the brake pads before driving.
3. Conduct a test drive to ensure the grinding noise is resolved.
