Hi Guys,

my racecar has a stock mastercylinder with drumbrake in front
and willwood disks at the rear and I am not happy withe the brake preassure.

Has anyone the same setup? Which mastercylinder are you using?

You get higher pressure with a smaller diameter mastercylinder.

The problem is not the higher pressure but the volume . We had the same when using the small racing calipers. You need more diameter to get more volume to each brake.
22 or 25 mm on the master cylinder. I have now 19 for the original front brakes and 24 on the rear for the aluminium calipers . That works perfect. The master cylinder is  from a 944 Porsche but i do not know the part number and model
