Re: brake drag

["Lino M. Valadas" <valadasl@osha.igs.net>]

Hello RC

I had the same problem exactly, however my car is an 86 5ktqw.  The guilty
component in my case was the brake booster.  I had replaced the Master
cylinder first and it did not fix it. Then I replaced the booster and the
problem dissapeared.  I did put my old master cylinder back on and the
problem  is still gone.
