No, I didn't know I had to...heard of doing this but no one (until now) could tell me how and I thought the air would come out during the normal bleeding process at each brake...silly me.

Can you elaborate on how to bench bleed the master? I'll be happy to go through this process as I'm stumped as to why I can't get any pressure out of this thing with a new master!

I'd also appreciate anyone's tips on bleeding MBs. I've owned 21 cars and never had a problem with bleeding. But, I've never installed a new master so I'm still learning after all of these years/cars.

Thanks!
