Steve,

OK, new calipers and pads. Got it. But, are the calipers and by extension pads parallel to the rotors? Your old ones were bedded in simply through use, the new ones may not be. This MAY cause a lack of parallel mating surfaces possibly on one caliper, i.e. the one that seems to not be working as well and then a difference in clamping areas.

My experience with Superformance cars (1855 & 2584) and other cars in general is that perfect doesn't exist. I had to shim the bracket on one corner of 1855 to get the mounting plate parallel. This may not be the problem but if it was out far enough it might cause a problem. I checked this with depth mic through the caliper mounting holes and measured to the rotor surface. I made an assumption that the caliper was good and my methodology was sound, perhaps not safe bet but still...

A lot depends on usage and expectations. More aggressive driving will force imbalance to appear.

Hope you get it worked out w/o going beyond the normal cobra crazy.
