Could you be a little more exact about the problem? Is it not driving the tracks or is it the "house" not turning..Both have a brake that is hydraulicly actuated..When you actuate a lever to turn the "house" or propel the tracks , hydraulic pressure releases the brake under the hydraulic motor..These brakes have multiple brake plates and steel disks and are actuated by a piston which locks up the function when pressure is not applied to the function...
