Sorry, you can get a better slave by buying a new one.

I bought both there a few months ago for #782. They said that they get them from the same place as Mitsu. -They just cut out the middle man.
Mine has been draining me for about 5 years. I keep thinking it will get better. Then I take it for a drive and the bad memories fade.

Do you mean the piston is wider or longer? If it's wider, wouldn't that be bad, ie have more crossface area, hence take more fluid to push it out the same distance, hence more pedal travel? I bought a new one and put it in about a month ago, and the piston was the same size as the stocker.

Well, here is my story. When I went to rebuild mine, I just went to a local store. I was in a hurry. I got the part, but the cylinder was too big. Maybe just a mm, but the bitch wouldn't fit. I tried a yet another chain thinking it was just a mistake, but I got the same problem. At this point I called up the dealer, gave them my vin number and ordered the rebuild kit.
I thought for sure I had it. Nope, too big. On the mitsu part, the stocker piston in green and I got a pink one that was just a tad too big to fit in the stock slave. Well, I had to fix my leaky problem cause this car was used to get to work. No backup. I just ordered a whole new one. When I did, it came with the pink cylinder.
I have no ideal why no one (even Mitsu) could not match the stock piston on a rebuild kit. It's only maybe 1, 1.5mm bigger, but when you are tring to rebuild the slave with a bigger piston, it seems a lot bigger.
To this day, I don't know why there is a green (smaller piston) and a pink (bigger piston) for the slave cylinders or why even the dealer with the VIN couldn't get the right part to me.
I can only guess that the stocker is NLA.

Yikes. Maybe that is from a Galant GSX or something. Did you order that using your VIN#?

I got it from Josh (Conicelli). To rebuild the slave and master is very easy. The slave rebuild kit is around $8 from partznet. I forget the price on the master...maybe $26?

If you don't want to read my above post...
Alright, Hydraulics 101. When you increase the size of a hydraulic piston, it now pushes more fluid with the same movement. Conversely, when you decrease the size of a piston, it moves less fluid with the same movement.
I'll give you two scenarios and you can vice versa them on your own. So, here's what happens when we change the master cylinder. Lets make the bore bigger. You'll be pushing the pedal the same amount as normal and because the bore is bigger, you'll be pushing more fluid. Since you're doing more work with the same movement, the work will be harder, i.e. the pedal will be stiffer. This translates into more clutch movement with the same pedal movement.
Now, lets make the slave cylinder bore smaller. With the same fluid movement coming from the master cylinder, the piston now moves more than it did before. Again, we have harder work with same travel so pedal is stiffer. Since the piston moves more, the cluch releases more for the same amount of fluid coming from the master cylinder.
Understand now? This applies to all hydraulic systems so if we discuss brake masters and caliper piston sizes, you'll be able to apply this to that as well.
