Front calipers are dragging. Had an issue at the track, brake fade. Tried to remove the calipers to see if they were dragging, long story short 5 of the 6 pistons were seized in the caliper, replaced the calipers with units off a newer model, cleaned and inspected them, good to go. Install and test run, brakes work great, noticeably more stopping power than before. However, calipers are still dragging, you can hear them at slow speeds, and on the front stand the wheel will get about 1 full rotation before binding (previously it would get ĺ rotation with the old calipers) What can I do to back the pads away from the rotors, and get them to return to that position after applying the brakes every time and not drag?

FYI: 98 ZX6R, Goodridge stainless lines, EBC FA188H sintered pads, í01 ZX6R calipers, DOT 4 fluid.

Are you rotors straight? The calipers will always drag but not a whole lot. Old school drag cars used to prefer drums all the way around because of that.

It's the EBCs, they like to drag. Happens to everyone who runs them.

Talked to Kasey (Casey) SP? At Fairfax cycles, he thought some part of the system might not be bleeding back properly. The calipers I bought off eBay came with the entire front brake assembly, so I threw on the master-cylinder last night.

Rode in to work today. Initially the brakes didnít have the bite that they did the day before, until they heated up, then they had that great bite again, and the 'whurrrrrr' from the front is now gone.

I am however a little concerned about if I properly bleed the master-cylinder. How do I ensure that I got all the air bubbles out of it?

Tonight when I get in Ill throw the bike on the front stand again and double check to make sure the front is no longer binding.

Id heard that about the EBC's, and experienced it on my friends buell, but this was soo much worse than a light dragging.
