I filled and bled my Clutch master cylinder the other day. I am using the same style internal master cylinder that comes on the new Shelby GT 500 (Green rubber around the spring loaded bearing) that does not have a bleed line. Here is a little trick that works really quick when bleeding the clutch.
Once you fill your reservoir with fluid and tap the clutch line a few times to get any bubbles that may be lodged along the line to the top of your master cylinder and you are still not happy with your pedal feel.
Required tools (assuming you are using a Wilwood style 5/8" master cylinder and plastic reservior): (1)Mighty Vac used for bleeding brakes etc. (2) 1 1/2" sink drain stopper (3) 1/4" drill bit (4) the black rubber sleeve that goes over your push rod that attaches between your firewall and clutch pedal.
First drill a 1/4" hole through the middle of your sink stopper, insert the sink stopper inside the black rubber sleve as mentioned above and use one of the black rubber hose adaptors that came in your might vac kit and place that aroun your drain stopper with the hose adaptor tapered end extending through the hole in your black sleeve.
Then firmly push the sink stopper into the top of your master cylinder reservior and attach the clear hose from your mighty vac to the hose adaptor and pull 25 lbs of vacuum and hole that for one minute. Then release the vacuum pressure and go inside your car and pump your clutch 10 or 12 times. Repeat this two more times and your clutch will be working properly with the desired feel.
If you like tomorrow I will post pictures of my little contraption but it works so well. This was the easiest clutch I have ever bleed.
