Is the brake peddle supposed to have a return spring to hold it in the full up position? I noticed that the clutch as a major, industrial strength spring assembly to keep it in the full up position. There is a spring hanging from the floor sheet metal but it may be for something else as I cannot find where it would attach to the brake peddle arm. I installed a new master cylinder and now have a leak between the brass fitting/block (to which the rigid line attaches to the system and the light switch is fastened). I am thinking of putting another copper washer in as a spacer so that it is tight but still at the correct angle for the rigid line to be threaded. Are there other solutions of which I have not considered?
