I have a 99 yz 400. I it seem like it takes to much force on the brake lever to get much response from the front brakes. I bled the brakes and checked the pads and everything seems to look fine. Brakes behave the same before and after i bled them and added new fluid. Compared to my ttr 250 which i could get to lock up with one finger my 400's brakes suck. Could it be oil contamination on the pads? The pads look fine and are still very thick. Is this normal or might there be a problem.
