Hopefully not posting a redundant thread, but my buddy called me after camping in Twin Lakes, Ca. (Bridgeport) and brought his '06 WR450F. He didn't get the chance to ride it, but said when loading it back up, front brake was locked. Thought maybe altitude (?) but checked it again in Bishop and still locked. Bridgeport is about 7000'. We've ridden Big Bear plenty and no problems. Any thoughts? Thanks in advance.
