Another Clutch Master cylinder bleeding tip.

The other day my shifter was hard to shift into gear and eventually lost the ability to get the transmission into gear. When I checked my clutch master cylinder it was empty. No fluid leaks at the clutch master cylinder firewall or inside where the clutch master cylinder connects to the clutch pedal. Check the transmission housing no leaks. So, I thought I would bleed the system. However, my bleeder screw was rusted up and would break if I put a wrench to it. How what to do can’t bleed the clutch system. A friend told me about an old mechanic trick to try; he said he could not guarantee it would work. He said fill the clutch master cylinder up and leave the cap off overnight.. The idea is that the air in the system will eventfully come to the top. Well I did what he said left the top off overnight. What the heck if it worked it would save me some money. Well this morning installed the cap on the clutch master cylinder and pumped the heck on the clutch and tried the see if would go through the gears and it did and the more I did it the better the shift. So, it worked!!! Thought I would share.

P.S. My clutch pedal never went to the floor and stayed, I guess if it was the slave cylinder it would have no pedal.
