[cad]

I've searched and searched and cannot find these answers.
Strange sells a 1.031 and 1.125 bore master cylinder. Their webpage says "assume 4 wheel disc"...

I have 2 piston Baer front disc and stock rear drum brakes.
1. Which size bore master cylinder works best?
2. Will I have to modify the stock brake pedal push rod or just alter the length and move it to the top hole?

Thank you,
Clark
