master cylinders for porsche brakes

[Steve C]

Hi

Im using 996 rears on the front (got 'em cheap) and Boxster rears on the rear (surprise) and my stock MC works great. Tried a 21 mm and couldnt stop the car when it was cold.

MattKab Try flushing your the hole in the your pressure switch with some metho, they do glug up.

I have found an odd thing happens a traffic lights, sometimes my car will roll, even though I think I have my foot on the brake.??
