Hey Rick, certainly alignment of master to linkage is worth looking at as the lads suggest. If it is showing nibbled edges on the seals that sounds like it is snagging something in the bore or overstroking and bottoming out on the end of the cylinder. Do you know it's not a heat problem causing hydraulic problems? What was your reason for changing master sizes? By putting the larger master you should displace more fluid (if you have a release problem) but it makes it harder to depress. I feel your pain as the HTOB are a SOB to get to but it doesn't sound like they are the problem. You should be able to go external if you want to and there is good reason to. It is just a matter of having the pivot points in the right place. There are some adjustable pivot points with set ups like Fortes but there are options with pivot hardware that come with a bell housing.
