Hey,
I was driving to work this morning and all of a sudden the brakes went out. The pedal was very hard and the stopping was hard. Like the power stearing went out.
Also, the engine wouldn't shut off! I had to open the hood and hit the STOP button on the ignition.
It's a 1984 300SD turbo.

I'm thinking it's a broken vacuum line but I'm not sure what it could be.
It's really got me worried.
Anyone got any ideas what it could be and how to fix it?

Thanks

Danny
