Brake pedal

2003 escape brake pedal squeals. Brakes have all been redone; however, pedal squeals when released. Wondering if vacuum leak or master cylinder. wmaloche@yahoo.com. Girlfriends car so must get fixed.

It squeaks where? The linkage by your foot/inside the dashboard? Or the master cylinder under the hood?

Hard to tell, sounds like pedal but only does going down road. Could be under hood.
