Im going to flush the old fluid on the system and use a synthetic brake fluid...

the way I understand the bench bleeding is, it shortens the process of bleeding the whole system by not sending the air contained by the new master cylinder into the lines! So, if I skip the bench bleeding of the MC, and just go on ahead and flush the system, wont I get out all the air out on whole system?

This is how dealerships do it. I've done many this way. Its much faster than throwing it in and trying to bleed all the air out. So yes I would say its a must do to shorten the process.

sounds good... I just wanna get a confirmation... I've installed the MC and all the lines already...when my bud mentioned the bench bleeding that I totally forgot(got too excited finishing the upgrade! lol).. I just wanna make sure that I can get away w/o bleeding the MC first.

yeah, but if the whole purpose of it is to just shorten the process, and nothing else, then I'll just do the longer process since I already have everything hooked up...I wanted to flush the line real anyway to get rid of the moistures..if there's any in there.

Most master cylinders contain the fittings and lines that you can do bench or oncar bleeding. But if you plan on flushing the system and replacing the fluid I'd say bleeding before installation isn't needed.

My new MC didnt come with that bleeding kit, that's probably the reason why I forgot about bleeding it..

its mainly for MC's that are angled when on the car like the old ford trucks etc so you dont have uneven fluid
