Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, flashlight, and brake pad gauge.
Safety Warnings: Ensure the vehicle is on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench.

3. Inspect Brake Pads

Use a flashlight to examine the brake pads through the caliper.
Measure the thickness of the brake pads using a brake pad gauge.
- Replacement threshold: Pads should be replaced if they are less than 3mm thick.

4. Check Brake Rotors

Inspect the brake rotors for grooves, scoring, or discoloration.
Use a micrometer to measure rotor thickness.
- Replacement threshold: Rotors should be replaced if they are below the manufacturer’s minimum thickness specification.

5. Reassemble

If the brake pads or rotors need replacement, proceed with replacing them as per manufacturer specifications.
Reinstall the wheel and lower the vehicle from the jack stands.
