My 03 CLS-6 does that from time to time when really cool out. I think it may be ever so slightly low brake fluid(cool fluid takes less space than warm fluid or flows less or something). After a stop or two the light goes out. The grabbing might just be the rotors getting slightly rusty. I notice that often if I wash my car and park it in the garage for the night. The next morning the brakes will be really grabby as I back out.

thanks for the reply. i have read in this forum the float probably is at fault.

The float likes being all the way at the top. Add fluid and it goes away most of the time.

However if u gotlowfluid it's likely cause ur brake pads are on their last legs and therefore u need new pads at a minimum

Check pads. Also brake fluid needs to be changed every 2 years.

Float are bad about sticking in the reservoir lid.

Had this happen to me before. It ended up resolving completely by just readjusting the cap/floater. of course it wouldn't hurt to at least look into whether or not the lines need to be bled... which is usually the other cause, afaik.
