Vladislav Posted January 5 Share Posted January 5 My personal experience figuring air brake issues was of that way I mentioned above. Read basic system, looked over what I had on a truck, found a valve I couldn't figure a matter of, googled "Bendix air brake valve" and idi'ed my one looking Google pictures. Passed that route for two trucks. Met unclear cases 2 or 3 times and got answers or advices on here. But had to explain what I was against of and my basic knowledges allowed me to do that clear enough. Good luck on troubleshooting!

Grind Posted Wednesday at 06:20 PM Author Share Posted Wednesday at 06:20 PM Update: Removing the Rotochamber and blocking that line off was the ultimate fix, since the front air over hydraulic brakes weren't needed anyway. Still have one leaky valve, impacts the secondary system only as the primary is charging to 120 but the secondary bleeds off to ~90 as the truck idles for awhile. I believe it's a relay valve and when summer hits I'll remove it and see if I can get a rebuild kit for it and get it dialed in. Thanks again for all the helpful feedback. Now just need some damn snow so I can feel better about all the money I sunk into this project. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73661-tracked-down-an-air-leak-need-help-iding-part/page/2/#findComment-569856 Share on other sites More sharing options...
Adkat Posted Wednesday at 11:53 PM Share Posted Wednesday at 11:53 PM Hard to tell, but that looks like an SR-1 spring brake valve 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73661-tracked-down-an-air-leak-need-help-iding-part/page/2/#findComment-569879 Share on other sites More sharing options...
