is it neccesary to bench bleed a master cylinder b4 installing it if i plan on bleeding it from the 4 wheels after i install it??

 

Yes it is. It's really simple. Just put some hose coming from each port back into the cylinder it came from, fill with brake fluid and pump until all of the air is out.

 

From what I've read it's not 100% necessary but it makes it a lot easier later.

 

I didn't cauz it sounded too complicated - I just bled the hell out of the system the regular way.

 

What you read and experiencing something for yourself are totally different. If you have no experience with it why give your opinion? It makes a huge difference. Having even a little air in the master cylinder is detrimental. It leads to leaking seals and spongy brake pedals. Not very good things. Do it right the first time. We're talking about brakes here, the lil things on a car that can save your life. You don't bolt down seat belts with just any old bolts do you?
