Operator called me and said as soon as he lets off the throttle the vehicle stops very quickly. When I arrived, I asked him to throttle forward. No brake release. Vehicle would move but brake was actuated. Brake area measured 230 deg. F. I screwed in the brake release screws to drive it to my area. I screwed in the screws a half turn to just barely lift the friction pad. Then when I throttle to move in either direction you could clearly hear the brake go on and off with normal throttle actuation.
I have read other posts where the brake can malfunction when quite hot. Is this true ?
I'm going to check to see if operator on third is using deadman to stop.
There was also a lot of oil sitting in the steering ring gear area where the drive motor sits. Not sure where it came from. It measured at 120 deg. F. It may have overflowed from heat expansion but will investigate.
Any thoughts ?
