Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery (optional).
Wear safety goggles to protect against debris.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which brakes are grinding.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang from the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the caliper slides and clean or lubricate them if necessary.
Install new brake pads, ensuring they are properly seated in the bracket.

5. Resurface or Replace Rotors

If rotors are scored or warped, either resurface them or replace them with new ones.
Clean the rotor surface with brake cleaner before installation.
If replacing, ensure new rotors are compatible with the vehicle.

6. Reassemble Components

Reattach the caliper over the new brake pads and tighten the caliper bolts to the manufacturer's specified torque (usually around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).

7. Final Checks

Reconnect the battery if disconnected.
Pump the brake pedal a few times to ensure proper seating of the pads and caliper.
