Fixed Bonaldi Booster

[THOMAS_GUADAGNI@domain.elided]

     Thanks to all the Alfisti who helped me diagnose why the brake booster 
     on my 67 GTV would not release. Turns out the fluid pressure sensing 
     pin was stuck in the down (brakes on) position and would not allow the 
     the small diaphram to retract which reverses the vacumn to the large 
     diaphram. Freeing up the pin put everything back in working order. I 
     never was able to find any documentation on these old boosters, so the 
     digest was invaluable.
