Front disc coversion problems

Finally drove my Demon around the block after installing a manual front disc conversion and found 2 problems. Hope you guys can help me out a bit!

I installed a brand new disc/drum master cyl and also a disc/drum distribution block. Thought all would be fine. Apparrantly I'm wrong.

Problem 1. Pedal feels a bit spongy....at least to me. I heard I should have a nice hard pedal. Bench bled the master cyl and bleed my brand new lines,, twice. Still feels a bit spongy.

Problem 2. Rear brakes locking up with moderate braking. Darnit, I thought the new master cyl and distribution block would create the right pressure, front and rear. Do I need an adjustable proportioning block for the rear line?

Maaan, this thing's been "under restoration" since October and I really need to get on the road! Driving to alignment shop Monday one way or another...


Mike,

Bleed your brakes one more time, starting with the rear passenger,rear driver,front passenger,front driver, in that order. Hopefully this will get all air out of the system, and give you a better feel.

The different m/c and brake system will give you a different pedal feel. If you think its going to stop like a modern car, well its not. As long the fronts are working (we know the backs are) I say drive it. Give it a chance to seat/settle. Hopefully this helps.

PS: An old HotRod trick to proportion rear brakes is to put
9" wheel cylinders in 10" brakes. :thumrigh:
