Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues.

2. Raise the Vehicle

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

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

Sub-step 1: Remove caliper bolts using a socket wrench and slide the caliper off the rotor.
Sub-step 2: Carefully remove the old brake pads from the caliper bracket.
Sub-step 3: Compare new brake pads with old pads to ensure correct size.
Sub-step 4: Apply brake grease to the backing of new pads to prevent squeaking.
Sub-step 5: Install new brake pads and ensure they are securely in place.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: Check the condition of the rotors; if they are warped or excessively worn, replace them.
Sub-step 2: Remove the caliper bracket bolts and detach the bracket to access the rotor.
Sub-step 3: Remove the rotor and install the new rotor, ensuring it is properly seated.
Sub-step 4: Reattach the caliper bracket and torque the bolts to manufacturer specifications.

6. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
Reconnect the battery.
