Topic: 68 disk brake proportioning valve disassembly

[preaction]

Surprisingly I didn't see in other threads or  ideas shared about disassembling any year brake proportioning valve specifically how to separate the two halves of the brass cylindrical body. I did get one apart and the replacement of the old parts with a rebuild kit are straight forward but getting the main parts apart without marring the half that doesn't have the hex end is a bit tough.

I had a machinest friend make me up a collet out of aluminum.

Scott, that's  about as good as it gets.
