Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, caliper tool, torque wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Remove Brake Components

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
3. Remove the brake pads from the caliper bracket.

3. Inspect and Replace

Sub-steps:
1. Inspect the brake pads; if they are worn down to the indicator, replace them.
2. Check the brake rotors; if they are scored or below the minimum thickness, replace or resurface them.
3. Clean the caliper and bracket using brake cleaner to remove any dust and debris.

4. Reassemble Brake Components

Sub-steps:
1. Install new brake pads into the caliper bracket.
2. Use a caliper tool to compress the caliper piston back into the caliper housing if necessary.
3. Slide the caliper back over the new brake pads and secure it with the caliper bolts, tightening them to the manufacturer's specified torque.

5. Reinstall Wheel and Lower Vehicle

Sub-steps:
1. Place the wheel back onto the hub and hand-tighten the lug nuts.
2. Lower the vehicle and use the torque wrench to tighten the lug nuts to the manufacturer's specifications.
