whats the difference bettween thos brakes?Might sound like a dumb ? but I have heard the terms.it was a add on with a switch on the shifter.Its a BD exhaust brake though.
Not a dumb question at all. The Jacobs is operated by vacuum. It will not fit with an aftermarket turbo because the vacuum canister sits about 1/4" from the firewall with a stock turbo. An aftermarket turbo moves it toward the rear of the truck about 1/2" or a little more. The Pac Brake is operated by air pressure. The air cylinder runs from the rear toward the front beside the turbo and will work with an aftermarket turbo.
Does yours look like this? If so it should work with an aftermarket turbo. And believe me, if you can keep it, do so. You'll be wanting it back on there if you take it off. That's the best upgrade you can make to a diesel.
