[TR] Brake problem

[Allen Hess]

Someone on the list, some time ago, said to hold the brake and/or clutch pedal down with a length of wood (or whatever works for you) wedged between pedal and seat (protect the seat). Leave it overnight, maybe more, and the air will rise to the master cylinder. It has worked for me more than once.
