Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, metric socket set, and safety goggles.
Raise the vehicle using a jack and secure it with jack stands. Remove the wheels using the lug wrench.

2. Remove Brake Components

Sub-steps:
1. Remove the caliper bolts with the appropriate socket.
2. Carefully slide the caliper off the rotor and hang it using a bungee cord or similar to avoid stressing the brake line.
3. Remove the brake pads from the caliper bracket.

3. Inspect and Replace Parts

Sub-steps:
1. Measure the thickness of the brake pads. If they are below 3mm, replace them.
2. Inspect the brake rotors for any grooves or warping. If damaged, replace them.
3. If calipers are sticking or leaking, replace them as necessary.

4. Reassemble Brake Components

Sub-steps:
1. If new brake pads and/or rotors are installed, apply brake cleaner to remove any manufacturing residue.
2. Install the new or inspected brake pads into the caliper bracket.
3. Reattach the caliper over the pads and tighten the caliper bolts to the manufacturer's specified torque (usually around 20-30 ft-lbs).

5. Final Steps

Reinstall the wheels and lower the vehicle from jack stands.
Tighten lug nuts to the specified torque (typically around 80-100 ft-lbs).
