Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, socket set, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Locate the brake caliper and remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or rope (do not let it hang on the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Check the thickness of the brake pads; replace if they are below the manufacturer’s specifications (typically less than 3mm).
5. Apply brake cleaner to the area and clean the bracket.
6. Install new brake pads, ensuring they are positioned correctly.

4. Inspect and Replace Brake Rotors

Sub-steps:
1. Check the rotors for any grooves or damage; if they are scored or beyond the minimum thickness, replace them.
2. Remove the rotor by unscrewing the retaining screws (if present) and sliding it off the hub.
3. Clean the hub surface and install the new rotor, ensuring a snug fit.

5. Reassemble the Brake Components

Sub-steps:
1. Reattach the caliper over the new pads and rotor.
2. Tighten the caliper bolts to the manufacturer's torque specification (typically around 20-30 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Test

Remove the jack stands and lower the vehicle.
Tighten the lug nuts to the specified torque (typically 76-83 ft-lbs).
Pump the brake pedal several times to seat the pads against the rotors.
