Getting air in the lines somehow

That is probably close to what mine ended up being, but if you need to replace it, the right stuff sell ones that on a dial that you just have to splice in as well.
I bought the MC in that kit with the valve and adjustable pushrod. I decided to use a stock on that I didn’t need to splice. I was having problems before this new valve. I just didn’t get a good pedal before I swapped it, now its only safe for about 2-4 tries haha
