Clutch bleeding question
When bleeding the clutch on a 997, why is it necessary to fully depress the clutch pedal?
When I just bled the clutch, I had about 8 psi pressure on the brake fluid reservoir from the power bleeder when opening the clutch bleeder valve. Upon opening the clutch valve, fluid readily flowed and I thought the line was flushed. Because of this I did not deem it necessary to depress the clutch. Will there be any significant problems if the clutch pedal was not depressed during the clutch flush? Thank you.

Since the bleeder is hard to access I found this to work the best. First of course I remove the bleeder cap, then I put the tubing over the bleeder and slide a stubby ratcheting flex head gear wrench over the tubing and loosen the bleeder. Reverse the wrench, tighten the bleeder and remove the tubing. Simple and no mess.

I've been thinking about cutting the side of a tall 9mm(or is it 8mm) socket so I can use a long extension and also have a hose on the bleeder. Last time I used a wrench I cut down to about 2" long.
What's the bleeder size again? 8, 9 or 10mm?
Thanks

The fluid deteriorates over time and loses it's effectiveness. It deteriorates with heat, takes on water and becomes more compressible (mushy connection between pedal and clutch). Also, the hoses, cylinders etc do give off particulates as they wear, when you change the fluid you clean the whole system.
