Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, wire brush, torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery for safety.

2. Raise the Vehicle

Use the lug wrench to loosen wheel nuts slightly.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully lift the caliper off the rotor and secure it with a bungee cord to avoid stressing the brake line.
3. Inspect the brake pads for thickness; if below 3mm, replace them.
4. If necessary, replace the brake pads with new ones, ensuring they are oriented correctly.
5. Apply brake grease to the backing of the new pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Inspect the rotors for any grooves or uneven wear.
2. If the rotors are damaged (scored or below minimum thickness), remove them by unscrewing the mounting bolts.
3. Install new rotors, ensuring they are clean and free from oil.
4. Torque the rotor bolts to the manufacturer's specifications.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel, tightening the lug nuts in a star pattern to ensure even seating.

6. Lower Vehicle and Test Brakes

Remove the jack stands and lower the vehicle.
Reconnect the battery.
Test the brake pedal for firmness before driving.
