Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to ensure safety while working on the brakes.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Inspect brake pads for wear; replace if the friction material is less than 3mm.
- If replacement is needed, remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor without damaging the brake line.
- Remove old brake pads from the caliper bracket.
- Apply brake grease to the back of the new brake pads and install them.
- Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 25-35 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotors for scoring or damage. Replace if necessary.
- To remove the rotor, take off the caliper bracket and any retaining screws.
- Install new rotors, ensuring they are properly seated and secure.
- Clean the rotor surface with brake cleaner to remove any grease or residue.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer’s specification (usually 100-120 Nm).
Reconnect the battery and perform a test drive to ensure proper function and to check for noise.
