'44 Chevy CMP C15 Master Cylinder

[Phil Waterman]

Hi Guys

Some photos of the master cylinder unit preferably with a original in the picture would help others understand the issue.

Would also be interested in the dimension of the bore casting, just wondering if the casting between the larger and smaller bore are the same? Wonder if there is enough metal in the walls to bore for the larger size?

My solution has been to have the original cylinders sleeved this has been a once and done solutions with sleeved master and wheel cylinders lasting 30+ years. With just replacement of the rubber parts every 5-7 years.

Cheers Phil
