I know this was talked about... but after doing vented front rotor upgrade on my 75 Cosworth, I have a low pedal that feels kinda spongy..
Does anyone drive the car like this? or is a MC upgrade a must?
It seems like it will stop ok just kinda lower than normal,( I have not driven the car yet,still in my garage) from what I read happens when you have a smaller bore MC than called for on the calipers, just wanna be sure its safe this way, and if I do upgrade MC does the front the rear bias valve from 75 stay or does it also need to be changed to match the bigger bore MC.
Thanks Al
