When I bought the car that is sitting in my garage (see sig), the guy told me that the master cylinder was leaking. Looking at it, there appears to be corrosion around where the master cylinder meets the brake booster and also at one of the outlets to the lines.
-Is there some way to replace a seal in there (like a gasket between the master cylinder and booster)? I'd prefer not to tear it down if there's nothing I can do.
-Also, would it be better to just grab one off a junked car (I have no idea what the cost would be)? Maybe just take the master cylinder and not the booster?
-And finally, are the master cylinders on the GSL and GSL-SE the same? It would make sense that they would be, but I'd like to be sure.
Thanks.

BTW, the master cylinder I have is from a (wrecked) GSL-SE that the guy had around. I also have all the GSL-SE brakes on my car, if any of that matters.

 

I just removed the master cylinder from my car and there doesn't appear to be a gasket of any kind. Your best bet would be to buy a new master cylinder. Rebuild kits suck and never seem to work. Also, if it starts to REALLY leak, the fluid could leak through the back side of the firewall and into the cabin, srtipping all the paint and giving everything a really nasty smell. Well, thats about it, hope it helps!
