If your brake pedal doesn't return all the way to the top, leaving 
you a bit fo free travel before you can feel something contact 
something else, then this can cause the wheel cylinders to lock up.  
It should affect both rear wheels equally, however.  A problem in the 
wheel cylinder should not cause harm to the MC.

The original MCs for 68-9 have not been available for maybe 20 years. 
In my moments of greater than normal stupidity I somethimes wish I 
had one for my 69, but those moments pass.  It was a very stupid 
design that only took VW two years to recognise, and the later style 
is a good replacement.  If you replace the brake light switch wiring 
harness with a later one you have everything you would want for a 
clean, functional, well designed installation.

Wow, got away with only a jack and a puller.  Pretty lucky.  I'm 
afraid I probably would have bought the whole thing, fixed it on the 
spot, and driven it home.  I've done that more than once.

Now, about jack restoration....
