Flashing Brake Light

Car Trouble Symptoms 
Flashing brake light on the dash board while driving, usually an indication of low brake fluid.

Flashing brake light is cause by a sensor that goes on when the brake fluid level is low. When the brake light only flashes and not permanently “ON” it means that the fluid level is just slightly low, in this case the brake light flashes especially when the car hits a dip or humps. Since the fluid level is low the fluid inside the master cylinder will slosh and did not make contact with the sensor thus triggers the brake warning light to came on.
