2
Check brake rotors for scoring or uneven wear.
3
Examine brake calipers for proper function and any signs of sticking.

Solution

1. Preparation

Gather tools and materials.
Park the vehicle on a flat surface and apply the parking brake.
Gather necessary tools: jack stands, wheel chocks, socket set, torque wrench, and brake cleaner.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper by unscrewing the caliper bolts (use appropriate socket).
Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
Remove the brake pads from the caliper bracket for inspection.

4. Replace or Service Brake Pads

If pads are worn down to the wear indicators or below the manufacturer's specifications, replace with new pads.
- Ensure the new pads are compatible with your model.
If pads are in good condition, apply brake pad lubricant to the backing plate to reduce noise.

5. Inspect and Replace Rotors (if necessary)

Check rotor surface for grooves or excessive wear.
If replacement is needed, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is secured properly.

6. Reassemble Braking System

Reattach the brake caliper over the new or serviced pads.
Tighten caliper bolts to manufacturer specifications (typically around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Torque Lug Nuts

Carefully lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the manufacturer's specifications (typically 100-120 Nm).
