NAMVET77 Posted April 24, 2021 Share Posted April 24, 2021 I have been lubricating my exhaust break with regular silicon spray. I'm being told I should be using high temp silicon spray. I can not find any high temp spray of any kind in the auto parts stores or on line. So, what is everyone using to keep the exhaust break working properly? So far I haven't had a problem but, if I need to change my way of lubricating the exhaust break assembly I need to know what to use. Any thoughts out there?

Dr4Film Posted April 24, 2021 Share Posted April 24, 2021 Many years back Fred White (RIP) a co-owner of this forum, had contacted PacBrake to specifically ask about lubricants for servicing the PacBrake. He asked if Tri-Flow was OK to use and they said that it would be a good one to use. I have been using that on my PacBrake ever since as he was also. I lubricate it according to their diagram and based on Fred's recommendation I installed a switch on the plate that holds the PacBrake relay so I can activate the PacBrake manually while lubricating it. You just have to make sure that the supply tanks are full of air. Plus you have to remove the air line to squirt lubricant directly into the cylinder air line port to lubricate the inside. I have attached the diagrams for the basic PacBrake and also the PRXB PacBrake which I have on my engine that includes an additional lubrication point.

Rikadoo Posted April 24, 2021 Share Posted April 24, 2021 I have to say in regards to what Dr4film states about using the "Tri flow" though I have not known until now about lubing the pac brake I have used the Tri flow on soooo many wear parts for years and it does a AWSOME job on everything I use it on. Even as a professional mechanic the shop I worked for would NOT supply it so I would purchase cans of it out of my own pocket to use when I had a special job that I wanted done right with NO comebacks! My only beef with it is it is such a slippery lubricant that the spray tip once used will seep until can becomes empty. Link to comment Share on other sites More sharing options...
Jim McGarvie Posted April 24, 2021 Share Posted April 24, 2021 I've been using mouse milk for years on the Pacbrake. I use it because we use it on turbocharger wastegates for airplanes, and those get pretty warm too. But I'm a big fan of Tri-Flow so might switch to that.

Gary 05 AMB DST Posted April 25, 2021 Share Posted April 25, 2021 Just had a member of the ranblinpushers tell us that his wastegate froze and now he lubricates that also. Where is the wastegate? Thanks Gary 05 AMB DST Link to comment Share on other sites More sharing options...
Ivan K Posted April 25, 2021 Share Posted April 25, 2021 If you have a variable geometry turbo you would not have a waste gate. Link to comment Share on other sites More sharing options...
96 EVO Posted April 25, 2021 Share Posted April 25, 2021 Had heard good reviews on 'Tri-Flow', so when I ran out of penetrating oil last year, figured I'd try it. Product worked fine. Can stopped operating with about 1/3 used! Won't be buying more! Link to comment Share on other sites More sharing options...

I had that happen number of times with different products so I feel your frustration. 1 Link to comment Share on other sites More sharing options...
96 EVO Posted April 25, 2021 Share Posted April 25, 2021 I'll look for it in the squeeze bottle, but some products just aren't available up here in the great white north. Link to comment Share on other sites More sharing options...
Rick A Posted April 25, 2021 Share Posted April 25, 2021 Well I liked the mouse milk comment, but what about high temp greases? http://www.omscllc.com/high-temperature-greases/ My manual says that the PAC brake is pretty much indestructible and doesn’t really need much attention. I’ve done 45k miles and never touched it. Link to comment Share on other sites More sharing options...
