When the peddle is pressed it becomes firm and will not release. If I bypass the hydro vack I have brakes but not very good. Wheel cylinders are ok. This is beyond me so if anyone has had this problem and solved it or any suggestions I will be very appreciative. Thanks Walter Beesley If this occurred immediately after you replaced your master cylinder your new master probably has a residual check valve built into it. You'll probably have to pull the master, disassemble, remove the check valve and reassemble. If the problem occurred prior to your replacing the master then the problem is in the hydrovac.
