I replaced the master cylinder but it is leaking from the bottom. Is it possible that it is cracked. Is there a gasket between the power assist and the master cylinder?

I thought I've answered this already If its leaking at the end of the MC where it meets up the brake pedal-The primary and secondary piston seals are leaking There's no gasket there

The seals are on the reservoir, correct? Do I need to replace the reservoir. Do I have to bleed the brakes if I remove the reservoir?

Whoa, Whoa, Whoa, I just asked a legitimate questsion. The reservoir is not the master cylinder and I just replaced the master cylinder. So should I replace the master cylinder and the reservoir
