Hey, novice mechanic and new stovebolter here. I'm restoring a 1959 Viking 60 who's brakes don't work. I can push the pedal straight to the floor without any resistance. Until last month, the brake system has been without fluid for around 10 years. When I added fluid, looked like it was dripping from around the master. A week after adding fluid and pumping the pedal for a minute, the master cylinder is without fluid again. So, I figure it's got some bad seals in the master cylinder. I took the master cylinder out and here I am.
From my reading, most trucks of this size have a 1-1/4" bore master cylinder but I have a 1-1/2" master cylinder. Right now I am leaning towards getting a rebuild kit for the cylinder if I can find one.
So, is it normal to find this in this truck? Where might I find a rebuild kit for this master cylinder? Am I approaching the brakes issue the wrong way?
