Just replaced my slave cylinder last Sat (37k miles on my '12). It's literally two bolts and a hose held on by a clip: take them off, pull the cylinder straight out, put the new one in, hook it up, then bleed. 45 mins tops, just watch out for that nasty exhaust (forearm burn)! The bleeding takes the most time... just gravity bled it. $90 later and 45 min of my time, like brand new. WHY DO THEY MAKE THESE OUT OF PLASTIC?!
