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 prevent any electrical issues.

2. Remove Wheel

Loosen lug nuts with a socket set while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid strain on the brake line.
- Remove old brake pads from the caliper bracket.
- Inspect the caliper slides for dirt or damage and clean them if necessary.
- Place new brake pads into the caliper bracket ensuring they are seated properly.
Tools Required: Socket set, bungee cord, brake cleaner.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the surface of the rotors for scoring or wear. Replace if they do not meet manufacturer specifications.
- If replacement is needed, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install new rotors, ensuring they are properly aligned and secured.
Tools Required: Torque wrench, socket set.

5. Reassemble Components

Sub-steps:
- Reinstall the caliper over the new brake pads and secure it with the caliper bolts.
- Reattach the wheel and hand-tighten the lug nuts.
- Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specifications using a torque wrench.
Safety Warnings: Ensure the vehicle is secure on jack stands before working underneath.
