[Vwdiesel] vanagon front brakes

[Libbybapa at wmconnect.com]

This slight veering when brakeing seems like the kind of subtle enigmatic 
problem that gives me whole new brakeing and sunspension systems.  Had a Dodge 
that did that.  After changing Everything, front and rear, I found out that one 
of the brake lines had a restriction in it.  It wasn't enough to stop the flow 
of fluid, just enough to slow it down.  I was always the one at the wheel 
with the wrench and my wife was the one pumping the pedal, so I never noticed the 
difference in pressure on the pedal.
Here's the question.  I have an '87 parts vanagon.  It has the later, said to 
be superior, front brakes.  Is it worth the hassle to swap all the parts 
over?  Is it just rotors and calipers, or do I have to get into it deeper?
