my daughter has a 2003 tahoe with a recent brake job done to it.the brake fluid is full.she sometimes gets a light that says service brake boost.the manual says when this light is on dont drive vehicle,take it to a dealer to be serviced.she has normal feeling,stopping brakes.what does this light meen and what needs to be done?

 

Welcome to the Tahoe forum. Not sure what the lite means but my guess is that the system would need to be bled.
