Solution

1. Preparation

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

2. Remove the Wheel

Loosen the lug nuts on the front wheel using a lug wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the front wheel.

3. Inspect and Replace Brake Pads

Caliper Removal
- Locate the caliper mounting bolts and remove them with a socket wrench.
- Carefully slide the caliper off the rotor without stretching the brake line.
- Support the caliper with a bungee cord or wire to avoid stress on the brake line.
Pad Inspection
- Remove the old brake pads from the caliper bracket.
- Inspect the pads for any signs of abnormal wear or damage.
Replace Brake Pads
- Install new brake pads into the caliper bracket, ensuring they are seated correctly.
- Apply brake grease to the backing plates and any contact points to prevent noise.
Reinstall Caliper
- Carefully position the caliper back over the new pads.
- Reinstall the caliper mounting bolts and tighten to manufacturer specifications (typically 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Rotor Removal
- Check rotor condition; if warped or excessively worn, replace them.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install New Rotors
- Place the new rotor onto the hub, ensuring it is flush and properly seated.
- Reinstall any retaining screws if applicable.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).
Reconnect the negative battery terminal.
