Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the vehicle safely.
Secure with jack stands to prevent any movement.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for thickness; replace if less than 3 mm.
- Look for uneven wear patterns.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Remove old pads and insert new ones, ensuring they are properly aligned.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-35 Nm).

5. Inspect and Replace Rotors

Inspect Brake Rotors:
- Look for scoring, cracks, or warping.
Replace Brake Rotors:
- Remove the caliper bracket if necessary.
- Slide the rotor off the hub.
- Clean the hub surface and install the new rotor.
- Reattach the caliper bracket and torque bolts to specification.

6. Reassemble and Test

Reinstall the wheel and torque lug nuts to specifications (typically around 100-120 Nm).
Lower the vehicle back to the ground.
Pump the brake pedal to seat the new pads.
Test drive the vehicle at low speeds to ensure the grinding noise is eliminated.
