Brake Master Cylinder Cups (Rings)

CP1 · Aug 24, 2016

Just wondering if anyone has ever found a place to buy the rubber cups like is used in master cylinders for brakes or some wheel cylinders. This is the ring type, the type with the hole in the center.I'm looking for some small ones (.400 ID shaft size by .750 bore size) Been looking around but haven't found a source yet. Trying to rebuild a master cylinder on an older combine and don't want to pay the high price for a whole kit, when all I need is a couple seals

try searching under MICO they may list one,i think that is where I located a.750 bore master cylinder for a gleaner combine and it was listed for a forklift as a .750 bore is a small one

If these are for use with standard glycol brake fluid, I can probably help you. If so, what is the width of the groove on the piston?

If the system uses petroleum based oil, the seals I have won't work.

You can still buy them at NAPA. It's by the box here.

Or buy the solid ones and put a hole in the center with a hole punch ?
