Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, brake cleaner, and safety goggles.
Ensure the vehicle is on a flat surface and the ignition is off.

2. Lift Vehicle

Use the lug wrench to loosen the lug nuts on the front wheels.
Jack up the vehicle and secure it with jack stands.
Remove the front wheels.

3. Inspect Brake Components

Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor; support it to avoid strain on the brake line.
Inspect Brake Pads:
- Check the thickness of the pads; replace if below the minimum thickness (usually 3mm).
- Look for uneven wear or damage.
Inspect Brake Rotors:
- Check the rotor surface for grooves or scoring.
- Measure rotor thickness with a micrometer; replace if below specifications.

4. Replace Components (if necessary)

Replace Brake Pads:
- Remove the old pads and install the new pads, ensuring they seat properly.
Resurface or Replace Rotors:
- If rotors are damaged, either resurface them or replace them with new ones, following manufacturer specifications.

5. Reassemble Braking System

Reattach the brake caliper over the new pads and rotor.
Torque the caliper bolts to manufacturer specifications (typically around 20-25 lb-ft).
Reinstall the wheels and tighten the lug nuts in a crisscross pattern.

6. Test Brake System

Lower the vehicle and pump the brake pedal to ensure proper function before driving.
Check for any leaks or unusual noises.
