G Body Manual brake problem

Chipper Chapman · 09-06-2011, 08:16 PM

Having trouble with a spongy pedal, but no air in the system. It's got stock g body disc/drum brakes, with a Master Cyl for a 69 camaro manual disc/drum. I have removed the proportion valve. Relocated the master cyl rod pin up about 3/4" from the orig power location.

So now the problem is that I have a spongy pedal, with absolutely no air in the system. And it's giving me greif with staging more than anything, I have a 5200 flash stall converter, and 2400 rpm the car is trying to push the beams.

Is it possible the master is too small of a bore?

If not, any suggestions?
