dcb smells... haha... he can't read this
I wonder how he knew I was posting.
Anywho... if you have a manual rack and you're used to no-vac brakes, then there is not really any danger except for at or approaching a stop in a heavy-traffic area. If you are not used to non-boosted brakes or your car has a highly-assisted steering rack like mine, don't do it unless it is a long empty downhill freeway with no crossroads.
