Here's a little tidbit from a Buick website:

"Brakes.....

The 1956 models with power brakes left the assembly line with what was called a displacement master cylinder. Instead of an internal piston it used simply a large rod going thru a seal that displaced the fluid in the sealed reservoir. The failure rate was high. Most were converted to the piston type master but there still may be a few left out there."


Imagine that...

This is telling me that the "Packard style" BTV was replaced with the one I posted earlier, that has the tall reservoir and normal piston with cups.

I refer you to a previous post of mine here: BTV threads
