I'm in Yuma, AZ for a couple of weeks and my PacBrake has stuck closed a few times in the last week. I use the brake every day and pull pretty hard at times on hills so doubt carbon buildup is the problem I haven't been able to find PacBrake lube locally here and the local Harbor Freight doesn't stock Super Lube oilers. Any suggestions?

 

I wasn't aware that a PacBrake required maintenance/lube...?

 

I use air tool oil. may not be the best but has worked for years.

 

Pacbrake makes a synthetic lube to oil the moving bits. You are supposed to apply a few drops to the linkages each oil change.
A few drops of synthetic engine oil should work fine.

 

I'll try some local truck supply's this AM for the PacBrake Lube. If I can't find it I plan to temporarily service it with PB Blaster until I can get the proper stuff sent to me. Should have done it long ago.
