Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheels

Use a jack to lift the front or rear of the vehicle, depending on which brakes are grinding.
Secure with jack stands.
Remove the lug nuts using a socket wrench, then take off the wheels.

3. Inspect and Replace Brake Pads

Remove Caliper:
- Remove the caliper mounting bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a hanger to avoid strain on the brake line.
Remove Old Brake Pads:
- Remove the old pads from the caliper bracket. Note their orientation for reinstallation.
Install New Brake Pads:
- Apply a thin layer of brake lubricant to the backing of the new brake pads.
- Insert the new pads into the caliper bracket, ensuring they are aligned correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Rotor:
- If the rotor is damaged, remove the retaining screws (if equipped) and slide the rotor off the hub.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective oil.
- Slide the new rotor onto the hub and secure it with screws.

5. Reassemble Components

Reattach Caliper:
- Position the caliper over the new pads and rotor.
- Reinstall the caliper mounting bolts and torque to the manufacturer’s specifications (typically around 20-25 ft-lbs).
Reinstall Wheels:
- Place the wheels back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and tighten the lug nuts to the specified torque (usually 100-150 ft-lbs).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to ensure proper pad seating and brake pressure is established before driving.
