Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts on the wheel slightly while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts; support it with a bungee cord or similar to avoid stress on the brake line.
2. Remove the old brake pads; check the backing plates for damage.
3. Install new brake pads, ensuring they are properly aligned with the caliper.
4. Reattach the brake caliper and torque bolts to manufacturer specifications (typically 20-30 Nm for caliper bolts).
Tools Required: Socket set, torque wrench.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Remove the brake rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
2. Inspect the rotor surface; if warped or heavily scored, replace it with a new rotor.
3. Clean the hub surface and install the new rotor; ensure it is seated properly.
Tools Required: Socket set, rotor puller (if needed).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle to the ground and fully tighten lug nuts in a crisscross pattern to the manufacturer’s specifications (typically 100-130 Nm).
3. Pump the brake pedal several times to seat the brake pads before driving.
Tools Required: Torque wrench, lug wrench.
