Was looking to see if anyone has installed a dual circuit master cylinder on a 46 1/2 ton with drum brakes? I checked the OEM single circuit brake cylinder and it has a 1" bore diameter and a 1.5" stroke.
I tried an ACDELCO 18M1020 (recommended by one of our Canadian friends) which has a 1" bore (but a longer stroke) It does not generate enough stopping power.
If you have accomplished this I would appreciate the master cylinder model # you used.
Best regards,
Larry
