MODEL T FIRST COMMANDMENT: REMOVE KEY FROM IGNITION BEFORE REMOVING INSPECTION PLATE !!!
Yer gonna get a lot of input on this, so lets go through the pre-amble... Before doing anything beyond an adjustment, COUNT and stuff RAGS all around the internal. A dropped nut or washer is a fatal blow and will usually require pulling the motor and disassembling.
Other than the brake lining being worn out or unriveted like Steves pic, it gonna require an adjustment. Theres 3 inside the cover. Low , reverse, and the brake to the rear. The nut on the brake may only require 1/2 turn to give some pedal back. As you adjust it, feel the pedal; there wont be much there by hand until the bottom 1/3 of travel is met. If theres very little adjustment left, get out the mechanics' French dictionary. Youll be due for a band re-line. Get your dad a folding chair to sit and watch, because youll be in and out of both doors like a jack rabbit and ya sure don't wanna have to cuss out the old man for wanting to help. Pulling the seat bottom and steering wheel will help as well... youll see. ws

Vous damned jouet voiture ! Je déteste votre stupide courage. Pourquoi trouvez-vous qu'il est nécessaire de me compliquer la vie et me traiter comme si je suis un genre de rectale médecin plutôt qu'un mécanicien ???
