If you added disc brakes to your car but did not change the master then that is the problem. Drum brake systems use a 10 lb residual valve in the master to keep the shoes nearer the drum. If you swapped for discs up front then the master is slightly holding pressure out on the pads hence the dragging. In a disc setup the cut seal at the piston maintains enough outward pressure to keep the pads near the disc. You can not just remove the residual valve as it is machined into the master, you need to get the correct disc/drum master for your application. Check the TSM circuit for the master and you should see the residual valve. Hope this helps, Bill Strobel Independent Towing Fayetteville NC __________________________________ Discover Yahoo!
