Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for wear indicators on the pads.
- If less than 1/8 inch of pad material is left, replace the pads.
Replace Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Gently slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are positioned correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for warping, scoring, or excessive wear.
Replace Rotors:
- If rotors are worn beyond the manufacturer’s specifications, remove the caliper bracket by unscrewing the bolts.
- Slide off the rotor from the hub.
- Install new rotor, ensuring it is seated properly on the hub.

5. Reassemble Brake Components

Reattach the caliper bracket and torque bolts to the manufacturer’s specifications (generally 22-25 lb-ft).
Reinstall the caliper and secure it with the caliper bolts, ensuring they are also torqued properly.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer’s specification (typically 76 lb-ft).

6. Final Check

Reconnect the battery.
Press the brake pedal several times to set the brake pads against the rotors before driving.
