Remove the brake fluid reservoir cap.
Use a funnel to pour new brake fluid up to the recommended level.
Clean any spills with a rag.

3. Brake Pad and Rotor Inspection

Tools Required: Jack and jack stands, lug wrench, socket set.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.
Inspect brake pads for thickness; if less than 3mm, replace them.
Check the rotors for scoring or warping; replace if necessary.
Reinstall the wheel and lower the vehicle.

4. Repair or Replace Brake Lines
