So I am need of a new master cylinder and have a question on which one to purchase from rockauto because they have 2 that I'm interested in but want to know exactly which one before I make the purchase because I've already bought expensive wrong parts before. The two cylinders I'm looking at are motorcraft ones and I just wanna stick with stock on this one.
First: MOTORCRAFT Part # BRMC162 w/ Speed Control at $72.99
Second: MOTORCRAFT Part # BRMC47 w/o Speed Control at $113.99
I'm really not sure at all what it means by with or w/o speed control so if you guys can explain. Also if you have any sugguestions on how to do the whole process. For example on how to bench bleed the cylinder and if I would have to bleed all of the brake lines or not. The reason why I'm replacing it is because their is a good amount of stainage on my brake booster where the master connects to. Also the real reason why I'm actually doing it now is that yesterday when I came out of the store my car was kinda hesitant to start and would kinda putter and buck in the parking lot and on my drive home that was about a mile from home. Once I got home I checked the car and there was grayish smoke coming from the exhaust and a foul odor as well as black soot coming from the exhaust. After reading up on it looks like it could be that there is a leak in the vaccuum hose and brake fluid is getting in. So last night I just put some seafoam in my gas tank since I had just filled up and the car drove fine but still had a little bit of smoking and soot coming from it. This morning I cleaned the MAF sensor and IAC valve just to see if it would help and I had been planning on doing this anyways. It really didn't make that much of a change other than it would pick up speed a bit faster. But nonetheless I am still getting a very small amount of black soot from the exhaust everytime I turn on the car and there seems to be a lot more condensation then there ever was before. So hopefully you guys can help me out on this one so I don't end up ruining my car or worse crashing so I greatly appreciate any help I can get from you guys. My car is a 2003 explorer sport 2wd with about 89k on the odometer.
