has anyone else done the booster delete using the 7/8 wilwood sport compact master cylinder
Image
i put one on my vert but haven't messed with it till now.
i went to bleed system today and suceeded..but low pressure
can hold brakes and turn wheels
called wilwood guy said the master cylinder was insufficient....i disagree
but gave good advice to check master cylinder
plugged end of MC off with plug ..pedal rock hard
so i tested his theory out and plugged off my rear brakes....still no pressure just running two calipers
i bled the front two quite alot...no air but still no pedal
the weird thing is that after you depress pedal and let off the resevoir pressurizes and pushes fluid out of the cap

just wanna know peoples experiences with this particular MC witch is same one in chase bays kit

i have 300zx calipers all around ....does anyone know the volume of brake fluid needed to run these calipers

any help appretiated.
