My non-assisted brake system uses two Tilton 74 series MCs and a balance bar, 7/8" for the front brakes and 3/4" for the rear. Trying to improve my stopping power, I started testing the front line pressure. The max I can get at a front caliper is a little over 500 psi and I should get 600 with a pedal ratio of 6:1. I adjusted the balance bar by a significant amount just to see what happens, basically 1/4" to favour the front brakes. The pressure did NOT go up, but stayed the same even though it ought to have gone up to 750 psi.
There are no external leaks and it doesn't seem like there are any internal leaks as the pedal does not continue to drop. There is no interference with pedal movement, i.e doen't hit the floor or anything.
The balance bar is not binding up and is perpindicular to the cylinders under full pedal pressure (front starts out with cylinder rod about 1/4" longer than the rear to allow more initial fluid transfer as the front calipers are larger than the rear ones).
Below is a picture of the set-up. I'm starting to suspect the front MC is internally leaking even though the pedal doesn't seem to be dropping. Any thoughts?
