After going through the threads about the defective WRX brakes, I wanted to try to duplicate the conditions that might cause a failure, so here's what I did:
1) My alley has the perfect brake test. It's loosely packed gravel over dirt, with two nice potholes about 6" deep, spaced about a foot apart on the left side of the alley. From about 40 mph, my wagon just stopped. The ABS didn't even activate.
2) We live right by commuter rail lines, so I tried a 40 mph hard brake while going over the tracks, applying the brakes both while still on pavement and having the wheels hit the tracks, then braking hard while on the tracks. The ABS went off the first time, but behaved normally.
3) Wet leaves by the curb, again from about 40 mph. Hard brakes, and the car didn't even pull. It just stopped.
First, I'm impressed. I know that I'm atypical because of how my car is set up, but I was really curious. For anyone who's interested, here's how I brake: firm pedal application at the start of braking, with necessary modulation (usually decreasing) as the car slows.
Hope this helps someone gather information, and I encourage all of you to find a safe spot and find out if there is indeed something hinky with your brakes.
