I washed my bike after a extra muddy day at the track and the next time I took my '06 YZ450 out the front (rear also but not as bad) brake had no stopping power. I could pull the lever as hard as I can and it won't lock up even on the dirt. I don't think it's the brake fluid as the lever has plenty of resistance. The only thing I can think of is somehow the mud/water/simple green from cleaning somehow did something to the pads and or rotor. I've never had this problem after washing the bike. I took off the pads and tried to scuff them up with some sand paper and did the same to the rotor and went back to the track today and it's a little better but I still can't lock up the front brake. This is strange because it locked up easy prior to the last wash. Any suggestions? The bike is only 4 months old and the pads still have plenty of life on them. Thanks!
