I've mounted a stock camaro ss slave cylinder to my press. ( i used my press just because it was the easiest way to do it, the press itself has nothing to do with anything)
I am now able to test a stock master cylinder and compare it to my modified master cylinder and see how much more my master moves the slave cylinder then the stock master.
While testing this today I found out that the brand new stock master cylinder doesnt hold pressure so now it has to be returned for a another one. Thanks alot GM your holding us up now!
Test results to come soon
