well some of you guys might know that Wilwood issued a national recall on their master cylinders a few weeks back, their 7/8 which most of us running manual brakes are using. one of my cars had a unit that needed to be recalled so I mailed it back and got the new one today. I typically do the bench bleed in my vise using the tubes and i push and push forever. it seems no matter how long i push the piston i can not get all the air out of the rear chamber. I called tech which was a waste of time on hold and the tech told me i should tilt the master forward 40 degrees in my vise, i never tried this or ever heard of anyone doing this. When i mount it in my vise the master is 100% level, in the car is about 90% level, slight tilt toward the rear. I also tried forcing fluid with a syringe at each port, still not luck once mounted on the car. If i plug both ports the master does hydralock but on the car the pedal travels to damn far it i don't feel safe as it is. im just beat up and exhausted, hot was hell doing this today after work. any of you guys suggest i try tilting it forward or rearward in my vise to see if i can get this to finally work? which makes most sense?
