Bleeding clutch (MityVac) I did some searching on here to see how to bleed a new master cylinder. I found lots of replies with many different unique tricks. Most of which required cutting up (or disassembling) and old slave cylinder which I didn't have. I did NOT bench bleed the master, here is what I did.
I installed the new master and put fluid in the resevoir. I cracked the bleeder on the slave and pumped the pedal to get all of the fluid out of the slave. Next, I refilled the resevoir and used a MitiVac with the small suction cup fitting that comes with the kit. Pump the MitiVac up to 15-20 and watch for bubbles. Keep pumping and releasing about 10 times. Have someone pump the clutch pedal a few times while you are using the MitiVac. The pedal was rock hard and clutch engagement was very smooth. It didn't take long and wasn't messy or difficult at all. Just go buy a MitiVac.
BTW, this is the method that GM suggests.
