Mushy Brakes

[sshockr]

Hey guys, having some trouble and would like to bounce some ideas around.

63 C-10 with all drums. Shoes are half worn. Just spent the evening getting the fronts to drag a hair with new adjusters (Will do the rears tomorrow). All new hydraulics from the wheel cylinders all the way to new master cylinder. Lines, hoses, everything.

I installed a '67 master cylinder meant for drum drums in order to split the front and rear channels. Bled everything (3 or 4 times). Yes I did lengthen the push rod on the pedal. But I don't know if I lengthened it enough.

My issue is the pedal goes almost all the way to the floor before anything happens. I can feel the push rod is about a half inch to short. Meaning a half inch of play can be felt before it engages the cup in the master. Then the pedal moves easily through the next 5-6 inches of pedal travel before everything suddenly grabs.

Longer push rod mod? More adjustment from the shoe adjusters?

My other question is the front brakes supposed to be on the back of the master?

Thanks, and sorry about the long post.
