Brake System Warning Light - Chevrolet 2008 TrailBlazer Owner's Manual

You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.

Brake System Warning Light

When the ignition is on, the brake system warning
light will come on when you set your parking brake.
The light will stay on if your parking brake does not
release fully. If it stays on after your parking brake is
fully released, it means your vehicle has a brake
problem. A chime may also sound when the light
comes on.
Your vehicle's hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.

This light should come on briefly when you turn the
ignition key to RUN. If it does not come on then, have it
fixed so it will be ready to warn you if there is a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push or the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have
the vehicle towed for service. See Towing Your Vehicle
on page 4-41.
