1996 Mack CH600 E7 427 Rebuild Kit for Jake Brakes

[Calebball25]

I have a 1996 E7 427. Out of a 1996 Mack CH600. I'm having issues with my jake brakes and wanted to rebuild them. But no where can I find any rebuild kits or just new jake brakes. I've called about everyone I know, talked to the mack and volvo dealer. It's the only dump truck we have and we need it back ASAP. Everyone I've talked to say they don't have them and can't get any. Is there any after market replacements? Or after market solutions? need help. Anything will be helpful thank you.

My guess is the Brake series is Jacobs 680?  What issues are you having?

Here are some documents that have part numbers that you are looking for. Dealer cant help?? IS it supply chain issues or is it lack of knowledge or caring?
