Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, safety glasses, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Disconnect the battery if working on electrical components.

2. Lift the Vehicle

Use the jack to raise the vehicle and secure it with jack stands.
Remove the wheels using the lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the brake caliper by unscrewing the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor; support it using a bungee cord to avoid stressing the brake line.
- Remove the old brake pads from the caliper bracket and inspect for wear.
- If worn below manufacturer specifications, replace with new brake pads.
- Apply brake grease to the back of the new pads to reduce noise.

4. Check and Replace Brake Rotors (if necessary)

Sub-steps:
- Inspect the rotors for scoring or warping using a feeler gauge or straightedge.
- If damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install new rotors, ensuring they are aligned properly.
- Torque the retaining screws to manufacturer specifications.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque.
Reinstall the wheel and secure with lug nuts.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque.
