I am trying to find a master cylinder foot my F3. I have called mpbrakes and eci but have not found an answer. What I think I need from various conversations and research is a 1.25" bore mm manual master Cylinder with a dual sump. Does anyone know of such a cylinder being used on any vehicle ever?

Any help is appreciated,
John

 

For brake parts....go to Napa Auto Supply: NAPA AUTO PARTS

You probably need this: Part Number: NMC M4572

That one is very close but is not a dual sump master. Right now my truck has a single sump master and no parking/emergency brake so I have only one point of failure. I was hoping to get it a little safer. I know some one has to have put a dual sump cylinder in a drum/drum system at some point in the past.

OK I have found the two possible cylinders. I have not called to find more information about them but they are for vehicles that have either disc/drum or drum/drum setups and they have a 1.25" bore. Mounting will need a custom bracket.
