My car has been sitting for a year. After driving for a week, the brake light came on. I checked, and everything in the breaking system seems fine. I rebuilt the entire brake system before it sat, but didn't touch the PDWA switch. I have one of the original brass switches. It appears there is some crud in the switch. I am guessing the piston is stuck, but I am not sure. Are these switches easy to rebuild? I was confused by the moss catalog. What kit would I order to rebuild this? Any help would greatly be appreciated.
