Brake Warning Indicator

The brake warning indicator receives its ground signals from the following sources:

• The parking brake switch provides a ground when the parking brake is engaged.
NOTE: The brake fluid level switch is part of the master cylinder and is not serviced separately.
• The brake fluid level switch provides a ground when the brake fluid level is low.

The ignition switch provides the brake warning indicator prove-out by supplying a ground when it is in the START position.
