Ok, got the brake pedal modified. If the pictures (before and after) don't show up here they are in my gallery. I re-installed the pedal in a lower hole on the pedal box, the MC rod position did not change nor did the pedal pad height. However the depth of the pedal in relation to the other pedals has changed with it being in a more depressed position at rest. I am not able to correct this because I have no adjustable rod on the MC, and was unable to remove it from the MC piston to change the length.
In flushing the old brownish orange hyd brake fluid I found a lot of gunk and sludge in the MC and so I removed it and cleaned it thouroughly. BTW it's 15/16" bore. I re-assembled and flushed the brake lines starting with the passenger side rear, driver side rear, passenger front and then driver front. I have clean clear fluid throughout. Now pressing in the pedal I feel that there is hyd pressure again, but the pedal does not feel completely restored. It does not return as crisply as I think it should. It feels kinda dead.
Thoughts on this please...do I need to purge more air that is still in the system? Do I have some other foreseeable problem like bad springs in the brakes? Disc front, drum rear. I'm not really sure what causes the pedal to return.
Thanks, John
