Priming the Clutch Master Cylinder, hints for doing it
From my last posting on this subject, (which was getting pretty long, so I am starting a new one) there seem to be 2 views on whether you need to prime the clutch master cylinder, with the majority recommending priming. And since I have already mounted the clutch master cylinder, could I prime it by filling the reservoir then use a long narrow skinny “something” that would fit through the firewall to push the piston in (assume this sucks brake fluid from the reservoir and therefore primes it)? Also, how far do you push the piston in, e.g. until it will go no further or should the strokes be less then the maximum travel?
What about the slave, e.g. does it need to be primed, also?

Just use the pedal to pump with. there shouldn't be a need to bottom out the master cylinder to prime it.The master cylinder pushes fluid thru the slave cylinder so no, you don't need to prime it. Make sure to bleed the fuid until no bubbles are visible in the fluid coming out of the slave cylinder bleeder. you really do need to recruit help for this procedure. Might as well break down and ask a neighbor or spouse.

Dang man, Just put fluid in the dang thing and pump it with the pedal. IF for some reason it does not prime, Then pull the hard line and put some fluid in the outlet side of the MC.
When you blead the slave it will prime the MC, Do it like I said in the other thread and report back, 99.9% sure that you will not have a problem.

Tennis, anyone
Bench bleeding is the best way,,, but since........ your going to need a 2 foot piece of clear 'fish tank' hose, a plastic 'dixie' cup, brake fluid. fill the plastic cup 1/4 full with brake fluid, place one end of the clear hose on the bleeder on the slave cyl. the other end in the plastic cup. open the bleeder, fill the master. get in the car and pump the clutch pedal ,,slow. the clear hose allows you to see any air bubbles passing through the hose. when no air bubbles are seen tighten the bleeder and check the clutch pedal presure. one person way to bleed the system.....

OK, its done – thanks to all who provided advice – in summary, it was not a problem to bleed the system without priming – though its probably better to “bench prime” prior to installing – but if you don’t want to risk spilling a full reservoir and damaging paint (either inside the engine bay or fenders), then installing dry and doing a normal bleed worked for me
