This does have a foot, puck, dead man switch. I recently replaced this as the contacts were getting a bit corroded. I did also find a service manual on ebay and purchased it. I went through the brake section and it talked about the air gap between the brake and the electromagnet. I checked and mine was up around 0.050". I adjusted the gap back down to 0.020-0.025". I had high hopes that this was it. It did not fix the issue. I also pulled and cleaned all the connectors going to the main brake and control board. It is still stopping after it runs a short period and definitely gets worse when it gets hotter in the shop. I'm trying to find where the brake temp sensor is or what the part number is to order a replacement. It plugs in just above the TP6, TP7 inputs but is not labeled on the brake controller? The part says Elmwood 92/33 3100U 235-33 L280.
Any help is appreciated.
Thank you. Bob
