What You Should Do
Do not drive the vehicle until the brake system is inspected and repaired.
Check brake fluid level and look for leaks around wheels and under the vehicle.
If fluid is low, top off with DOT 3 or DOT 4 brake fluid (check owner's manual).
Have a professional mechanic bleed the brakes to remove air, and inspect the master cylinder and all brake components for leaks or damage.
