What causes the warning light to come on? Brakes 'feel' right with normal pedal travel, fluid level isn't low. This isn't a on a Buick, just a general question.

Could be an abs sensor.

nope, last of the dinosaur pre computer Quadrajet equipped 2 piece rear seal Gen 1 sbc. No ABS sensor. Thanks for the reply though Wendy. Btw, I heard nasty Wendy wasn't.
The light is supposed to indicate an imbalance between the front and rear systems...

Meaning what S10? Imbalanced line pressure? Wouldn't that indicate a leak?
Not necessarily, just that one system is putting out more pressure than the other. Enough to move the shuttle piston inside the valve so it's off center, thus triggering the light. Have you bled the brakes or done any other work lately? If it's a disc/drum car, have you "self adjusted" the rear brakes lately?

No, I haven't "self adjusted" the rear brakes, not exactly sure of what you're talking about
Good point! Forgot completely about that...
When backing in reverse, tap the brake pedal a few times. This will adjust the rear brake shoes, assuming the adjusters aren't corroded up...
