C5 brakes swapped still not much better HELP!
Hello,
I swapped the C5 front brakes into my `89 Formula LS1.
There is no huge improvement in braking than the stock small discs I had in front. Do I need to buy some better master cylinder or proportioning valve?
What can I do to take advantage of my C5 brakes? My VAC gauge is showing 10 when I hit the pedal, on old stock brakes it used to go to about 20. What is wrong?
I would be grateful for your advice.
Cheers
Marcin
PS: The rear is drum, soon to be swapped to LT1 Fbody rear discs.
