Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Pads

Remove Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Brake Pads
- Check the thickness of the brake pads. Replace if they are below the manufacturer's recommended thickness.
- Use a caliper tool if necessary to retract the caliper piston.
Remove Old Brake Pads
- Unbolt the caliper using a socket set and hang it safely without stressing the brake line.
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads
- Apply brake grease to the back of the new pads and install them into the caliper bracket.
- Reattach the caliper over the new pads and tighten the bolts to the manufacturer’s torque specifications.

3. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition
- If rotors are warped (evidenced by runout measurement), they should be replaced.
- Remove the caliper bracket and then the rotor.
Install New Rotors
- Clean the hub surface and install the new rotor.
- Reattach the caliper bracket and tighten to the specified torque.

4. Wheel Alignment and Balancing

Inspect Alignment
- Check for visual signs of misalignment such as uneven tire wear.
- Take the vehicle to a professional alignment shop if misalignment is suspected.
Balance Tires
- Ensure all tires are balanced to prevent vibrations. This can be done at a tire shop.
