Good info about the calipers, thanks.

My brake set up (with 48mm YZ forks/wheel) is 320mm disc, oem xtr caliper, oem master cylinder an EBC HH pads.
But I�m not happy. The braking power is good for me, but not the feeling, when braking, if I apply 20% power, it brakes 20%, but if I apply 60% power, it still brakes 20%... unless I apply more power, but then it�s all or nothing... Is this what english people call wooden brakes??

The pistons are clean, I�m going to try new pads, because it�s the less expensive.
