SeriousSeverity: Serious - have it checked soon
Brake fluid level warning fault
Key terms: Powertrain: engine, transmission and emissions
1What it means in plain English
The brake fluid level is below the safe range, which can mean a leak or worn brake components and can affect braking.
2Common causes
- Brake fluid leak (lines, calipers or master cylinder)
- Worn brake pads or discs
- Faulty brake fluid level sensor
- Air in the brake system after a repair
- Brake fluid at the end of its service life
3Can I drive?
Do not drive until the brake system has been checked. Low brake fluid can mean a leak, and braking may be reduced or lost. If the pedal feels soft or the red brake warning light stays on, stop safely and have the car recovered.
