First: which brake light is it?
- Red brake warning light: treat as urgent (fluid / system warning).
- ABS light: brakes still work, but ABS may be disabled (needs diagnosis).
- Traction/ESP light: can be sensor related and linked to ABS faults.
Common causes of a brake warning light
✋ Handbrake not fully down
Simple, but easy to miss — especially on slopes.
🧴 Low brake fluid
Often caused by worn brake pads (fluid level drops as pads wear).
💧 Brake fluid leak
Leaks from calipers, brake lines or master cylinder can be dangerous.
🛞 Worn pads / discs
Some cars trigger warnings when pads are low or sensors are damaged.
🧠 ABS sensor / wheel speed sensor
Common cause of ABS/traction lights and fault codes.
⚙ ABS module / wiring
Less common, but wiring faults or module issues can trigger warnings.
Can I keep driving?
- Red brake light + soft pedal / low pedal: don’t drive.
- ABS light only: drive carefully (no ABS) and book diagnostics.
- Any pulling, grinding, or burning smell: stop and get it checked.
