Brake Fluid Level Warning Light
The Bulb Check: Brake Fluid Level Warning Light
When you start the vehicle, the brake fluid level warning light will illuminate, but it should go off after 1 to 2 seconds. If it does not, there is a problem with either the brake fluid level or the brake fluid level warning light system.
If the vehicle is equipped with a messaging system, no message will display as long as the brake fluid level is at an acceptable level. The message system is basically a "no news is good news" type of system. When a brake fluid level message is displayed, it means there is a problem with either the brake fluid level or the brake fluid level warning system.
What to Do: Brake Fluid Level Warning Light
If the brake fluid level warning light illuminates or a brake fluid level message is displayed, the red brake hydraulic light is not displayed, and the brake system performance feels normal, then take the vehicle to a qualified repair shop for a complete brake system inspection and diagnosis as soon as possible. The brake fluid level warning light can be an indicator of wear in the brake pads and/or shoes. As the brake linings wear, the brake caliper pistons will be more extended, causing an apparently low fluid level.
