In the last week or so, every time I take off from a start, my emergency brake light and chime come on until the inertia from takeoff "comes forward" again, at which time it finally stops.

Any ideas what I should look at?

I would check the brake flued

You were a few hours quicker than I. That thought hit me this afternoon. The level was below the top of the reservoir, but didn't look excessively low to me. I topped it off to be certain, and that seems to have solved the problem.

Thanks for the input!
