Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check thickness; if less than 3mm, replace.
- Look for uneven wear or cracking.
Replace Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Lift the caliper off the rotor and support it with a bungee cord or similar.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors

Inspect Brake Rotors:
- Check for grooves, scoring, or rust.
- Measure rotor thickness; if below manufacturer specification, replace.
Replace Brake Rotors:
- Remove caliper bracket bolts and detach the bracket.
- Slide the rotor off the hub; clean the hub surface.
- Install the new rotor, ensuring it is seated properly.

5. Reassemble Components

Reattach the caliper bracket and torque bolts to manufacturer's specifications.
Reinstall the caliper over the new pads and torque caliper bolts.
Reinstall the wheel and lug nuts, tightening in a crisscross pattern.

6. Final Checks

Reconnect the battery.
Pump the brake pedal to seat the pads.
