I should probably just make forum threads for my dumb questions rather than bothering people in pm. Anyway, I'm going to be replacing the o-rings in my clutch slave cylinder. I have the car split and I've undone the two bolts and banjo ends. I thought it would come right out but it does not budge. Bonked it with a rubber mallet gently, also tapped with a punch to try and rotate it. Should I give it bigger whacks or is it attached somewhere else that I can't see requiring more disassembly? PB blaster maybe? I do not want to damage anything.
