There is a bunch of research involved with chosing the correct master for 4 wheel disks. The bore and stroke of the master must be right for the size of the piston. If its too small it wont move enough fluid and you will have a spongy, weak pedal. Too much fluid and you will have a hard pedal.
I put my disk brake kit together with help from Randall Thomass of Performance unlimited who tought me about fluid movement in relation to bore and stroke of the piston and how it affects your pedel. I ended up using a master for a late 70's Lincon that came with factory 4 wheel disks.
Keep in mind you cant use one that is ment for drum/disk combo, it wont move the right amount of fluid to correctly work the pistons of calipers on all 4 wheels. There is a write up in our tech section I did on rear disk conversions.
