Brake System Fault
CriticalBYD · Braking System
What does this warning light mean?
This warning light indicates a fault in the brake system. Unlike the parking brake warning light, this specifically signals a failure in the brake hydraulic system or intelligent brake booster. It will also illuminate if brake fluid levels are low or brake assist has failed. Note that in some models, this shares the same indicator as the parking brake light, but activates under different fault conditions.
Can I drive?
Stop driving immediately
What to do
Safely pull over immediately and do not continue driving. A brake system fault can significantly increase stopping distances or result in complete brake failure. Contact a BYD authorised service centre or call for roadside assistance straight away. Warning: Driving while this light is illuminated is extremely dangerous.
Likely causes
- —Low brake fluid
- —Brake line leak
- —Brake booster fault
- —Brake pad severely worn
