My son has a 93 Toy p/u, 4wd that just had a strange problem. It was working
fine, but from a stop he went to push in the clutch and a strange sound
(snapping) happened and no clutch movement. Pedal won't  return from the
floorboard. We thought the master cylinder but no luck. Took it to a
mechanic and he said the pedal bracket is bent out of shape and won't allow
enough force to operate the clutch. Said the firewall is known to be flimsy.
Sounds kind of hokey to me. Anyone have any experiences like this or any
ideas?
Thanx
Rick
