I bought another xt about 4 weeks ago and only got it put on the insurance today . the bike had been garaged for about 8 months but is in good nick, here"s the problem when i rode it today i noticed a shake in the front brake when breaking lightly it def feels like a warped disc but the bike only has 8k miles on it and the disc has no wear on it . I took the front caliper off cleaned everything and nothing is sticking, pistons etc are moving fine.The only thing i can think of is that the disc is supposed to float slightly if it had seized up and doesn"t float would this cause the strange braking feeling. any one any ideas. cheers
