So, what's your biggest dummy moment??

at the time i had a VW Passat
me and the wife had to go to Philadelphia, about a 1500 mile round trip
i knew the brakes were getting close so replaced them, new pads and rotors on all four corners
car ran flawless there and we were on out way back
we just passed by pitsburg on the way back when toe brakes went out
and i mean OUT
pedal trhough the floor and nothing
so i pulled over, crawled underneath and saw notting wrong
no leaks, nothing
fired her back up, pumped the pedal several times and it came back to working order

i was anxious the entire drive home and get her up on blocks as soon as i got in

and there it was, clear as day, the front left caliper had come off
i must not have tightened the bolts and they backed off and fell out
the pads were missing BUT the caliper had wedged itself onto the mount and this restored pressure to th system
