Hey fellas, I am currently running a set of wilwood brakes upfront and decided I needed to change the brake master cylinder. Did some research and found the 735i e32 but it only has 2 ports for brake lines, where as the car has 3 ports. Would connecting the two lines with a T piece fix this problem?
TIA

I think you'll find the 750i E32 25mm MC is for an ABS system, so it only has front and rear out to the ABS unit which then has 3 outputs, LR front and a common rear output.

Word is you add a T piece to split the fronts on a non ABS set up.

This will give you a firmer pedal - but lower your braking power for the same input "push" - depends how strong your leg is! all because of the reduced mechanical advantage of the original 19mm or 22mm bore
on the stock MC.
