HAs anyone ever had their front brakes just lock up?...I was going over some railroad tracks. Thank God I was only doing maybe 5 or 10 miles an hour when all of a sudden, my front brakes just locked up..A fellow behind me tried to help me get it off the road but it wouldn´t move so finally I fired it up and I gave her the gas to force her to move off the road...After a careful examination we couldn´t find anything wrong and the brakes unlocked and I rode it home VERY SLOWLY...Had I been going any faster this could have been a disaster...Any ideas Guys? My Raider is a 2008..
