Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the emergency brake is engaged.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the wheel with a socket wrench.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor, ensuring the brake line is not stressed.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads into the caliper bracket, ensuring they are seated properly.
5. Compress the caliper piston using a brake caliper tool to accommodate the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or excessive wear.
2. If rotors are damaged or worn beyond specifications, remove the rotor by unscrewing the retaining screws.
3. Install new rotors by aligning them with the hub and securing with screws.

5. Reassemble Braking System

Sub-steps:
1. Reinstall the caliper over the new brake pads and secure it with caliper bolts.
2. Replace the wheel and hand-tighten the lug nuts.
3. Lower the vehicle back to the ground and fully tighten the lug nuts to the manufacturer's torque specifications.
