Speedies are light up front, and will lock up there first, in my experience., and under even moderate braking conditions. If road bumpy at all, they will chirp as you bounce. This is an alert to let up just a tad, and pump if you have time. A situation can happen where there is no time to think, crash is eminent and reflex just mashes the pedal and hopes for the best. Only did that once a long time ago, and never in the Speedster, so far. With all four locked up, unless your tires are really worn differently, you will go in the direction old Mo dictates, and all you get to do is hope all comes to rest before the crumple or the cliff's edge.
