Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface, and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands.

3. Remove Wheel

Using a socket set, remove the lug nuts from the front wheels.
Take off the wheel and set it aside.

4. Inspect Brake Components

Check Rotors:
- Measure rotor thickness using a micrometer.
- Inspect for any warping or scoring.
- If warped, replace rotors.
Check Brake Pads:
- Measure the thickness of the brake pads.
- If they are worn below 3mm, replace them.
Inspect Calipers:
- Ensure calipers move freely and are not stuck.
- If caliper pistons are seized, replace the caliper.

5. Replace Parts if Necessary

If rotors or pads need replacement, follow these steps:
- For Rotors:
  1. Remove the caliper bracket.
  2. Unbolt and remove the rotor.
  3. Install the new rotor and torque bolts to manufacturer specifications.
- For Brake Pads:
  1. Remove the caliper by unbolting it.
  2. Replace old pads with new ones.
  3. Reinstall the caliper and torque bolts appropriately.

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
