Reply to "Brake question...."

When I built the MGB I put disk brakes in the rear and larger brakes up front. I replaced the MG master with a wilwood. In looking for the proper size I had a spreadsheet I worked it from one end to the other.

It started with:
The coefficient of the brake pads,
the number of brake pads,
The caliper pistons, numbers, bore,
the rotational distance of the pad contact,
The tire diameter
The weight distribution,
Difference in these variable with the front and rear,
MC diameter
Pedal to MC ratio,
and a number other things.

All this works back to required pedal force and required MC volume.

In the end a smaller bore gives you more travel, less pressure and a better feel until you run out of volume.

There are a few more things involved then what it seems on the surface.
