Like I said earlier I removed the push rod early in my ownership.  I 
don't left foot brake (not coordinated I guess) so I have never seen any 
problems.  The brake servo is still plumbed to the manifold so it still 
gets vacuum from the engine.  You would have to apply two good hard 
brakes without closing the throttle to start to feel the lack of braking.

I have autocrossed the car once, in the rain.  I have a purpose built 
rabbit EP car and I got my best placing ever in that bone stock 4kq in 
the rain on street tires.   No problem with lack of push rod.
