How about a weird idea?
For years I was concerned about letting the clutch slave fully extend and the consequences...ie. the whole thing falling apart. Until I did a post mortem on a bad clutch slave after doing a nono. While it was out of the bracket and cluch fork, I stepped on the clutch pedal and intentionally blew it up. Got news... it takes a fair amount of pedal effort to kill one in the fully extended position. So here's what I did on my most recent clutch system installs. One. install the master and the nylon line. fill with fluid and let it gravity bleed out. Two, remove the slave from the retainer bracket(if installed on the trans) on the trans and allow the pushrod to extend fully or if the slave is a new unit, disengage the retainer straps holding in the pushrod and allow to extend. Three, find the appropriate sized allen wrench for the bleeder screw on the slave. Four, install the slave on the nylon line when you start seeing fluid dripping out of the line. Five, here's where it gets interesting... brace the slave pushrod against a hard object such as one of web pockets on the trans and push in the pushrod by hand after opening the bleed screw. Six, when the pushrod is in the fully retracted position, close the bleedscrew. Allow the pushrod to once again fully extend SLOWLY. Seven, repeat steps five and six until you start getting a shower. This only took two or three repeats for me. Another indication that the slave is filling up is it will become harder to push in due to the amount of fluid filling up the slave. That is a good thing. Eight, if you are intalling a new slave, reinstall the retainer strap and install the slave assy. If you don't have the retainer strap anymore, open the bleed screw a little, so when you fight in the slave assy, the pushrod will go in a little easier. I had the second of the two to work with
Here's my premise for the whole idea....when working properly, the pushrod travel on the clutch slave is 1/4 to 1/3 of the total travel the salve is capable of handling. By fully stroking the slave unit, more air is displaced and more fluid is drawn in from the vaccumn, therefore tha job goes quicker. Fact of the matter is you are going to get a brake fluid shower either way, minus well make it alot shorter
yes, I can already see the ****** reference inuendo coming......
