Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely raised using jack stands.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for uneven wear or glazing on the brake pad surface.
- Measure thickness; replace if below manufacturer specifications (usually around 3mm).
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor (do not disconnect the brake line).
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are positioned correctly and seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for warping, scoring, or excessive wear.
Replace Rotors:
- Remove the caliper bracket if necessary.
- Unscrew the rotor retaining screws and slide the rotor off the hub.
- Install the new rotor, securing it with retaining screws.

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Torque caliper bolts to manufacturer specifications (generally around 25 Nm).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to manufacturer specifications (usually around 90 Nm).

6. Test Brakes

Pump the brake pedal to seat the pads against the rotors.
Conduct a low-speed test drive to ensure the brakes function properly and check for any remaining noises.
