Title: Please help air leak at parking brake
Post by: James Bock on February 25, 2024, 02:22:40 pm
I have a very steady air leak when I disengage the parking break, circled in the pic is where it is coming from. It feels like it is coming directly from the three wires circled in red. It only leaks when parking break is off.
Any ideas, help would be greatly appreciated.

I'm trying to leave to get back home 400 miles from where I am (Munford Alabama).

Thanks,
James

So it is coming from the parking brake switch, where the three wires plug into. Anyone know of a part number, or field expedient fix?

That is a common part on air brake trucks Napa should have it and most truck stops also. Depending how much air is being lost it could be drivable if the compressor keeps up with the loss. I have had to drive one of my cranes with that valve leaking to get back to my yard. After that I kept a spare in the truck. It doesn't have to look the same just needs the same ports. It can even be a reverse one that releases when pulled to get you home.

Mike, got a plug for the fitting and I believe it's going to work.

If that is the exhaust port you are plugging you may not have a park brake.
