My park brake light came on while driving one day. The park brake is not on, and i checked all my lines. The pedal feels really soft, like I have air in the system, and when I checkeed the master cylinder, the front portion was empty. Question-- is the front portion of the master cylinder supposed to be empty, and if not, will checking my brakes and bleeding the system get rid of the warning light?

Fill the brake M/C and bleed the system then comeback with results-firm brakes-no spongy-and lite still there test the brake level sensor and the Emergency park brake switch.

Hi there,

The light is a low fluid warning a you should identify where the fluid has gone first, if the pedal is soft there will be air in the system, check all brakes, re bleed and check for the leak carefully, start here.
