Yes, it is illegal to drive with only one brake light not working. It is a safety hazard and can result in a traffic violation.
It probably indicates that both your other brake lights are burned out and need replacing. BTW: It is illegal in most (if not all) jurisdictions to drive this way.
Check the brake light bulbs, Check the brake light fuse, Check the brake light switch, In that order.
the brake light driver side not working
this could be the cause of low brake fluid or that your foot is on the brake and it is indicating that the ABS is working.
The brake light switch is not air actuated.
There are likely one of two reasons why a brake light on a Brava is not working. Either the bulb is burned out or a fuse is blown.
probably the brake light switch on the pedal if none are working at all
The law requires for all lights to be on when driving so yes it is illegal to drive without tail light
possibly have a brake light out
Bulbs blown, or corroded sockets.
Possibly a problem with the brake light switch It is linked to the gear selector If the switch is faulty you cannot select gears Make sure the brake lights are working
Yes , as long as the red " BRAKE " light in your dash is not on * the ABS warning light means that a problem has been detected with the Anti-lock Brake System and it is not working properly It could be a fuse , a sensor , or some other problem
