I know this is a stupid question, but I got a new m/c and I cant see where you add the fluid. Anyone know, I know this is going to be a nightmare bleeding this set up:argue:

Is there a filler somewhere higher up on the firewall that gets plumbed to the master? '54 and '55 at least had a filler on drivers side firewall and line running down to the master under the floor.

on my '54 and '55s that filler is bolted to the firewall and goes down to the master that is mounted to the frame under the floor. I'll take a look at the '57 in a couple of hours and report back. This is one in a '54 circled in blue

No buster. You grab the steering wheel at the bottom and pull when you push down. NJ

Was a booster standard or optional?

Optional. So we ve determined that that is the m/c fill up tube I jusy need to connect it somewhere. Im redoing the brakes. New m/c, wheel cylinders, brake lines

Just checked, no booster someone must have removed it,,,,mmmm,,Im thinking what to do,,,,,maybe try standard brakes???:beatdeadhorse5:

I would replace the brake booster. I am no expert, but the expense, up front, of replacing the booster could be relatively insignificant compared to the cost of and accident if you are unable to stop on-time. Again, no expert... I haven't forgotten about the pics I said that I was going to send...it has been a very busy few days here!
