MG Midget and Sprite Technical - Dual Line Master Cylinder

Howard,

Sorry I can't help with the bore size, but I put a dual line master on my 65 Sprite. I used the one with the big round cap, and I changed out the entire pedal assembly, bracket, cylinders, and all. It did take a little cutting and welding in my case.

I liked the result just fine.

3/4" ?

Depending on your front brakes it can also be 7/8"
Problems ?
If you need the 3/4", you'll not find it and if you use the other one on a front disk brake car, you 'll throw the clutch slave piston out of his bore...

Guys,
I have disks up front and standard rear brakes, I want to fit a dual circuit system as fitted to the American spec, but using a Willwood master cylinder hence I need to know what bore I should use7/8 or 3/4.

Many Thanks,

Howie.
