Had to replace my brake lever and ended up replacing the whole brake assembly beacuse of the pad adjust getting stuck. I used park lube in lube the seals of the piston assembly. Sram uses Sram brake grease that has castor oil in this. Are the seals going to be broken down by the park lube or should I be okay?

I would imagine you will be okay you might not feel the exact same feel as you would using the grease that is Optimally designed for sram brake leavers... But I don't think that the polylube will have as much effect on seals as say using a different grade of hydraulic fluid would.
