Re: Weird hissing from the brakes!

Have you lost any fluid?
Does your pedal, when working, does it operate correctly, firm pressure, full pedal. firm pressure, half a pedal.

Dual mass flywheel, can not have anything to do with this, as your pedal will be down before the van is running.
You can prove the last sentence in the morning, dip your clutch, before starting the van.
With it coming back up,( if no fluid loss,) after driving, would be suspecting master cylinder not holding pressure

I think, aesthetically, car design is so interesting - the dashboards, the steering wheels, and the beauty of the mechanics. I don't know how any of it works, I don't want to know,
