Brake Master Cylinder Replacement..

[Soccer21]

Hey guys, I'm new to this board..I own a 1992 Mazda MPV with 138K and it runs like a charm!..Just got done changing the rear brake shoes a few days ago, and also have been experiencing very very soft brakes...bled the lines still no resolution...front brakes are fine..

So..noticed that the brake fluid is NOW BLACK (after adding new fluid)...figured that an internal seal in the Master Cylinder is the culprit...soooo...I ordered a remanufactured Brake Master Cylinder from the dealer..only $52!@!@!@

My question is this:

Can anyone guide me or post a link on how to remove the Brake Master Cylinder? Also is this a tough job? Does the Brake booster have to come out along with it?

Any help would be appreciated!!
