2000 Replace Master Cylinder with ABS?

[MarkF2]

Anything special to know when I replace the MC on my 2000 Grand Voyager with ABS?

I have been chasing a fluid leak for a long time. I've already replaced the MC (at a shop) , Booster (myself) and all of the rubber lines (myself). I think the shop that replaced my MC reused the old reservior and that is where the leak is. Since I could not get just a new reservior I ordered a new MC that includes one.

My concern is getting air in the ABS system. Is there a way for me to do this myself (w/o getting air in the ABS) so I don't have to pay a garage?

Thanks

Maybe there's a way you could just replace the reservior, but if you break loose the lines at the MC it's going to be hard not to get air in the ABS system. There's no way to bleed the ABS without the tool.

Rick99 is right. As soon as you crack the lines, you're gonna have to bleed the ABS. Rather than pay to have a scan tool bleed procedure, you might want to buy a MC that comes with the reservoir and just change it out. Probably cheaper.

Not sure how much cheaper b/c I had to buy the full unit even though I would only use the reservior. I guess there is no harm in trying this out. Worst case is I have to swap out the MC cylinders in addition to the reservior. Best case is reservior swap and I'm done.. Would I even have to bleed the lines if I only change the reservior?

If you get any air into the lines in the process, you'll need to bleed them and do the ABS bleed. I would think that you can empty the reservior with a turkey baster, but still leave enough in the master cylinder that no air will get in the system when you put the new reservior on and fill it up. I could be wrong on this depending on the angle at which everything sits-- you'll have to use your judgment. Just don't touch the brake pedal with the reservior off.
