This is just a warning to everyone who drives, CHECK YOUR BRAKE FLUID LEVEL. If the fluid gets too low, the master cylinder will suck air. When it sucks air, you lose brake pressure.
All vehicles have a red “BRAKE” light on the dash. It comes on for only three reasons:
1. You left the parking brake on.
2. The system has lost pressure.
3. The fluid has level has drop past a critical level.
You should NEVER drive with this light on. I am more than willing to bet the light was on long before she ran over three people. The corroded GM brake line defense does not hold water with me.
