Is there any difference between a brake MC from a drum brake 620, and a brake MC from a disk brake 620???

Bigger brakes. Bigger mc. Bee put a 720 booster and 15/16th mc in my truck.

Yes there is a difference, the non disc brake M/C has a 10lb residual valve built in, so if you use that on a disc brake vehicle, it will smoke the disc brakes. A drum/disc brake M/C has a 2lb. residual valve for the front disc brakes, and a 10lb. residual valve for the rear drum brakes.
