Stupid brakes

My overly awesome father picked me up a caliper yesterday so that I could finish the brake job last night. However, even after power bleeding twice, the pedal is still a bit squishy. I might have to replace the MC - luckily I have a brand new, never used one in the other car, so while it'll be a pain in the butt (especially since I just put 2 full bottles of ATE Super Blue through Yeti), I may have to bite the bullet and just do it.
