Hey guys I did a auto to T56 conversion and I put a adjustable master I forgot who made it but the problem is that when I don't use my car for like a day when I get in it in the morning and it's cold my cluth pedal goes to the middle and then it gets hard I have to pump it and then it goes back to normal and it works perfect. Any help would be apriciated thanks.
