One of the brake cables snapped at the clevis and I get a replacement. it threads on both ends. I started by pulling the rubber boot then the U pin then the spacers, washer, spring and an additional spacer. I see that the cable is threaded way inside the tube and do not see a clear way to get it out. I have the model with the covers above the drive train and I opened it but I do not see any additional help from going in that way. all I can think of is some special tool that goes in the tube and engaged the square portion of the cable at the back of the thread. Any help in understanding this and figuring out how I can get this cable replaced would be appreciated. I need to get this machine back in service. Thanks, Roveer
