Had not heard of that. Very interesting idea.

The car is light enough you may be okay without the vacuum power brakes. I wouldn't see it weighing that much. You might try it first with just the vacuum line pulled to see if you are willing to drive full time like that

[edit] Thanks Aerohead, I didn't know a diesel Rabbit would even go 80mph!
I wish people would stop recommending this all the time... its not even close to the same thing as a manual brake swap. If you remove the vacuum line on his car and don't plug it at the pump, its gonna blow oil everywhere on the next drive. Then he's also going to be fighting against the vacuum booster because he's gonna be trying to push all its volume of air through the little hole where the vacuum normally is, as well as fighting a rather large and fairly strong spring designed to keep the diaphragm from activating the brakes when there is higher than normal vacuum in the booster... its not even close.
