Default Master Cylinder Flare Type

I was wondering if someone here can confirm the flare type on the 09-13 corvette master cylinder. There is a rumor out there it uses a 37 degree double flare versus a SAE 45 degree like every other car in America. Looking on-line all corvettes use a 45 degree or bubble flare. There are not fittings out there that I could find suggest a 37 degree double flare. Anyone know 100% certain?

You could call a place like SJM Manufacturing, Inc. (724) 478-5580 and ask them. They make line lock kits and would probably know.

The C5 master cylinder is 12 x 1mm bubble flare on the front port and 12 x 1.5mm bubble flare on the back port.

They are the same master cylinders as to bore size other than the flare sizes?

Thanks,

I haven't done this in a while, but NAPA used to carry every brake line made (just for the ends) and you can easily form your own bubble flares.

ISO bubble flare has nothing in common with a 45 degree double flare.
