33 HR Master Cylinders

[Scot]

I would like to verify which master cylinder that I should use for the rear brakes and which for the front brakes. My thought is that I should use the larger bore (.75") master cylinder for the rear brakes and smaller (.625") for the front brakes.

However, the manual (version 1Z) is not helpful on this. On page 108, it states that both master cylinders have the same bore. However, in my kit the 2 master cylinders have different sizes: .625" and .75".

Thanks.

That's what I did with my Willwood brakes. I remember that it failed to bleed properly so I had to replace it and the photo of the failed cylinder is burned in my memory.

I also sent an email directly to FF and Jay provided the quick response that I should use the 5/8”(.625) Master Cylinder for the Rear & the ¾”(.750) Master Cylinder for the Front.

My logic was backwards...glad that I asked for confirmation :-)
