Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

2. Remove Brake Components

Brake Pad Removal:
1. Locate the caliper mounting bolts and remove them using a socket wrench.
2. Carefully slide the caliper off the rotor. Support it with a bungee cord or similar device to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
Rotor Removal:
1. If necessary, remove the caliper bracket by unscrewing the bracket bolts.
2. Slide the rotor off the wheel hub. If it's stuck, tap it gently with a rubber mallet.

3. Inspect and Replace Components

Inspect:
1. Check the rotors for deep grooves or significant wear. If they are damaged beyond the manufacturer's specifications, they should be replaced.
2. Inspect the caliper for any signs of fluid leakage or damage.
Replace:
1. Install new brake pads into the caliper bracket. Ensure they are correctly positioned.
2. If necessary, replace the rotor with a new one, ensuring it is clean and free of rust or debris.

4. Reassemble Components

Reattach the caliper bracket (if removed) and tighten it to the manufacturer's torque specifications.
Reinstall the caliper over the new brake pads and secure it with the mounting bolts. Torque to manufacturer's specifications.
Reinstall the wheel and lower the vehicle.

5. Final Checks

Pump the brake pedal several times to seat the brake pads against the rotors properly.
Check brake fluid levels and add if necessary.
