2003 Z05 brake issue
We had a track day here on Sunday. On Saturday, I swapped put the street pads for track pads.
Let me explain further. About 2 years ago, I put Wilwood Aero6 (6 piston) calipers on the front, and 4 piston calipers on the rear. I also installed the speed bleaders on all calipers, so I could bleed brakes by myself. Up untill now, they've been great!
This morning, before going to the track, I bleed the brakes, and took it for a test drive.
At first, all seemed fine. However, during the test ride, I felt the peday was a little soft. On the way home, the pedal kept getting softer and softer. I figured I forgot to tighten up the bleader and I was right. I see brake fluid all over the wheel and tire on the drivers side.
So, I jack up the car, fill up the resevoir, and proceed to pump brtakes. The pedal at first went all the way to the floor. I had to pull up the pedal with my foot. No leeks. Good...NO!
Now the brakes seemed to be locked. At this point I can't tell if it's just the one wheel that I was working on, or all 4 wheels.
If it was the one wheel, I might could understand. But all 4?
If it's all 4, did I do something to the brake master cylinder when the pedal went all the way to the floor and I pulled it up with my foot?
Any suggestions I will take.

Turns out, it was the panel beneath the drivers side dash. When the pedal went to the floor (when the speed bleeder was left open), I pulled the pedal up with my foot. The panel under the dash somehow got wedged on the brake pedal , and was jambing it against the pressure in the system. popped the 2 remaining pins in the panel, dropped it, reinstalled it correctly and voila'...brakes are fixed!
