i looked at my 280e haynes book and if it is the same on yours, which i would think it is, the limiter for the brake pedal is actually the stop light switch. it threads into a bracket with two nuts to locate it. it can be moved in or out. i bet you will find that the po just screwed it in all the way and it is too far in. if it is missing the second nut you will need to find one so you can adjust the position.

good. this is simple to fix. and easily overlooked.
