Man, I'm stumped...
The Commando has 4 wheel disk brakes. I just swapped out the old drum/drum master cylinder for a new disk/disk master off of a a 69 vette. Everything was working well.. well I think. When the swap was done I could push the peddle down about 2 inches hardly any travel in the peddle. I was able to lock up the rears going forward and the fronts gonig backwards. Well today, I was comming home down little cottonwood canyon, so I was using the brakes, and shortly after exiting the canyon the brakes started to engage... I had to shift from 4th to 3rd, and then from 3rd to 2nd just to keep moving Well I pushed it all the way home and when I pulled into the garage all four wheels were smokin.. and the peddle wont even go in at all...
So I take off for awhile and when I return I try them again and they go all the way to the floor..... wtf.........
So I bench bleed the master again, try and bleed the rears and they won't bleed...There is no gravity bleeding, and they wont pressure bleed. I know that the master moves fluid because when I bench bleed it, it moves. I swap the front line to the rear and the rear to the front and I'm able to bleed the rear brakes.
It kind of sound like the master might be bad. God, why did I buy this one from Ebay. It was "new in the box"..
Anyone ever experience this before?
