Ryder is bringing a 2012 wr450 over for me to figure out what making it stick. Says he went to a 2hr race Sunday and when he got home and rode it to get some mud to fall off his bike his front brake stuck and put him down. Says his lever would not budge. I told him to loosen his cap to see if that helps, said he got it to work but locked up again after awhile. Any known problems on this ? New leftover bike. Thanks MB I will let you know what I find latter. Hoping for a head up.
