Just to expand on a topic that started in the Mark Pombo crash thread on RRAX; how many of you guys do the left-foot brake test going into heavy braking zones? I never have, mainly because I questioned its usefulness. I always figured that by the time you realize something is wrong, and react, you're probably going to be around the same point on the track where you would have been going to brakes anyway. Also, since you're just tapping the brakes, I figured you probably wouldn't notice a failure that would occur under heavy braking. But, as is often the case, I'm probably wrong...

So how about it? How many of you test your brakes, and of those how many have found a problem in time to take a different course of action than you would have had you not checked them?
