Hey Ya'll ! Here is my problem.. Fished yesterday , backed boat in no problem..went to back trailer in water and the back axle brakes locked up...i checked the lever that is supposed to be depressed to unlock them and it appeared ok.There is a cable that is for use if the trailer and truck become seperated...i'm thinking that might be the culprit...anybody had this issue before?The Rig is a 2006 Blazer w/ Blazer Trailer. Any suggestions are appreciated.Thanks:wallbash:
