Original hydroboost brakes. No vacuum needed. I’ve never seen any traditional booster on a diesel either.

Mines leaking a little and I should probably rebuild/replace it soon.
Yep, and you probably never will see a vacuum booster on a diesel equipped unit.
Not unless that diesel has an external vacuum pump.

You can't use a conventional booster on a diesel - diesel engines don't generate enough vacuum.
