Slave cylinder or system?
 

The slave cylinder on my truck is leaking. I can buy a new one for about $60 locally, but ive read that there a huge pain to bleed. My question is, should I buy it and swap it out, or should I just buy the pre-bled system? And what is so hard about bleeding them?

My slave cylinder went out of my 96 f250 5 speed and I bought a new one from in town for 40 bucks. Me and my dad had to old one off and new one on and bleeded in about 30 mins. It only took that long cause dad didn't check the oil in the resovor. Its not hard really. Just need to people, one to pump the clutch while one tightens and loosens the bleeder screw. Really easy. Im 16 and did everything. Dad just pumped the clutch.

I ended up just buying the whole pre-bled assembly from rock auto, after taxes, duty, and shipping it was around $120. I just heard they were hard to bleed completely but at least I know for next time.
