Master cylinder leaking around reservoir

[Intropy]

My master cylinder is leaking around where the reservoir mounts. Can I fix it or is it time for a new one?

check the clamp. mine came loose and did the same thing, i tightened it up and not a drop came out until i swapped to a mechanical setup If not, just buy a new one. cheaper and less headache

Are you talking about the brake master? You can buy new seals for it. I just overhauled mine as part of a brake update even though it had no issues. There are two seals (upper right in the pic) that hold the reservior to the body. The seals are like $2 from Cherry Hill. The master rebuild kit has the two piston assemblies, cerclip, and o-ring for $53 from Cherry Hill but doesn't include those two seals.

Yes, brake master. Thanks, those seals are what I need! How did you find them on cherry hill's site? Having a little difficulty at the moment.

Unfortunately you can't drill down to it on their site. I use ASA to find the part number for ordering. I have a call in to Cherry Hill on another topic so maybe I can have them look up my order and tell me the part numbers I ordered

That would be most appreciated.

OK, got the info for you:

MB238309 Seal for the master cylinder reservoir. You'll need qty=2.
MB857842 Master cylinder rebuild kit for AWD cars with ABS. If you're draining the system anyway you might want to service this.

Sooooo many thanks!
