Hello, I've got some problems with the swing motor brake on a Terex (schaeff) hr20. When I have been using the machine for some time(it can vary from some minutes to hours). Suddenly the swing brake will not disengage. Seems like the brake, since I can hear the engine is getting some more load when I try to swing, but it wouldn't move.. I am going to search for the solenoid later today(I guess it will be the pilot pressure that is suppose to release the brake?), and hopefully that's the fault, but if not.. Anybody experienced the same problem and could give me some good advice?
