Thank you Brazilian Y60, it's relaxing that somebody is feeling your pain you can share what you went through with them, i just had my clutch master cylinder failing again tonight, it's going down and doesn't hold the pressure, thought a lot about it this morning and did a quick diagnosing last night, i have come to conclusion that i used cheap parts, my new brake fluid in the clutch master looking black and dirty, it amazes me because it's less than a month since i changed the master and fluid, i think cheap part is main problem here
