Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the wheel is on the ground.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check brake pads for thickness; replace if less than 3mm.
- Look for uneven wear or cracking.
Replacement:
- If replacement is necessary, remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid stress on the brake line.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.
- Compress the caliper piston using a brake caliper tool to accommodate the new pads.

4. Inspect and Replace Brake Rotors (if needed)

Inspection:
- Check for grooves, scoring, or warping on the rotor surface.
Replacement:
- If replacement is required, remove the caliper bracket and then the rotor.
- Install the new rotor, ensuring it is aligned properly.
- Reattach the caliper bracket and torque bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and remove the jack stands.
Torque the lug nuts to the manufacturer’s specifications.
Pump the brake pedal a few times to seat the pads before test driving.
