Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use a jack to raise the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it without straining the brake line.
- Measure pad thickness; if less than 3mm, replace.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads in the same orientation as the old ones.
- Reattach the caliper over the new pads and secure the bolts to the manufacturer's torque specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Brake Rotors:
- Check for significant scoring or uneven wear.
Replace Brake Rotors (if needed):
- Remove the caliper bracket (if applicable) and then remove the rotor.
- Clean the hub surface and install the new rotor.
- Reattach the caliper bracket and ensure all bolts are torqued to specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and tighten the lug nuts to the manufacturer's specifications.
Lower the vehicle off the jack stands.

6. Test Brake System

Pump the brake pedal several times to seat the new pads.
Check brake fluid level and top off if necessary.
