Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a level surface, engage the parking brake, and disconnect the battery if necessary.

2. Raise the Vehicle

Use the jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands to ensure stability.

3. Remove Wheel

Use the lug wrench to remove the wheel bolts and take off the wheel.

4. Inspect and Replace Brake Pads

Inspection:
- Check brake pads for thickness. If they are less than 3mm, they should be replaced.
- Look for uneven wear or cracks.
Replacement:
- Remove the caliper bolts using a socket.
- Slide the caliper off the rotor and support it with a bungee cord or rope.
- Remove old brake pads from the caliper bracket.
- Apply brake grease to the back of the new pads and install them in the bracket.
- Reinstall the caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer's specifications (usually around 20-25 ft-lbs).

5. Inspect and Replace Brake Rotors

Inspect rotors for grooves or scoring. If damaged, replace them.
Remove the caliper bracket if necessary, then slide off the rotor.
Clean the hub surface with brake cleaner before installing the new rotor.
Install the new rotor and reassemble the caliper bracket.

6. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer's specifications (usually around 80-100 ft-lbs).
Reconnect the battery if it was disconnected.
