Air leaking into air intake stack (parking brake NOT applied)

[dilligaf13]

Yes. One outlet connects to the double check valve. The other outlet connects to the air stack and allows for the venting of air, though the stack, when you engage the parking brake.

Quick release valve

I would very much appreciate a picture of the Quick Release valve. If you could, please use a pointer to point it out. There’s a lot of plumbing under the drivers step.
Could you tell me where you bought the replacement? Thanks!

Largest valve in the Step Bill. It is called a QR1 valve. Haldex # 32005 Found at napa or truckpro or other heavy truck parts place. Or Ebay.

Thank you Simp! I’m just wondering, is there anything you DON’T know about these vehicles?
Thanks for the quick answer...
