This is the only car I've ever driven with non-power discs.  It has 13" disks all around with B body front calipers and old Trans Am rear calipers.  I figured the excess travel was due to the volume of fluid required for the calipers.  Am I wrong?  I've got nylon/braided steel lines and the pedal feels solid.  My Malibu has the same calipers and lines with power assist and it stops great with "normal" effort.

Interesting - I would expect the large rotor diameter to give great 
stopping with reasonable effort.
So you have it set up without any lost pedal motion, and it just takes a 
lot of travel at the master cylinder to get full effort?

- could something be pushing the pads back from the nominal rotor 
surface, requiring the extra fluid volume to apply?
