Have a 574 with brake, hydraulic issues. At best I can get a right brake with bleeding but never a left or both. Can get fluid out of right bleeder but never the left one, just air. The right brake does not last long either. Sometimes if I get on a downhill/sidehill I will loose PTO, steering, etc. Read in other posts about having to clamp off a transmission return line but have no clue as to where that is or how to do it. Could someone walk me through this process. Want to try bleeding the proper way before someone soaks me a pile of money to repair something. Thanks guys
