Brakeless and Still Leaking
It's the old "good news, bad news" thing.
The good news is that my master cylinder easily came out last night in preparation for a rebuild and Tom installed the last defroster hose so we can cross that item off the list.
The bad news is that my rear window leaks worse now than it did before it was reinstalled with a new gasket. Tom took a good look and discovered that when they'd installed the window, they hadn't placed the rubber gasket correctly over the pinch-weld. Tom carefully removed the chrome strips and, using a screwdriver, adjusted the gasket so that it now sits correctly. After all the water has dried, he will apply more Window-Weld all the way around both between the glass and rubber and between the rubber and body. Unfortunately, I have to un-cross this item from the To Do list. Here's a picture of the gasket's cross-section (from the Clarks' Corvair Parts website)
