Pete 389. Parking brake won't release, please help

Those are simple push to connect air fittings that any dealer should carry. Take them off and replace them yourself nothing complicated.

 

Pull it out.

 

Yes, push the ring down then pull the airline. A lot of the time you'll have to make a fresh cut on the airline when using a new fitting. Obviously cut it as straight as possible.

I'd recommend anytime you buy a replacement air fitting to always buy an extra so that next time you'll have one on hand for those emergency situations. It's a lot cheaper than having to call out a service truck.

 

Something like this is good to have in your toolbox. For cutting airline.

 

Theres a fleetpride in Sacramento off 80 if your passing through that way on Monday. They carry various airline connections.

 

What I meant was push on collar, pull on line. Sorry I wasn’t clear.

 

I guess I am stunned that two different mechanics couldn’t figure out where the air was leaking from?
Great learning lesson here so let us know on Monday if you get the new fittings and the issue is fixed.

 

Peterbilt actually figured this issue out and side exhaust now. Just read the whole thread and a lot of good info. Glad the 2nd guy figured it out. The first guy was a parts chucker for sure!
