ok , today i lost pressure in my clutch and i was wondering what this could be ? i checked the fluid and it was to where it should be and not only that , but a rich oily black color . i have never seen this and am wonderiong , since the pressure does come back ... could the rubber line be collapsing on me ?

 

Either deterioration of the line or the cups inside are going bad.

 

yeah , that is what i was thinking , i got the fluid replaced and it was black granules ... like the linning of a hose .
thank you doc

 

No problem. Time to get one of those stainless ones!

 

lol . i just found the one i want lol. does anyone know the life span of them ?

 

My brake fluid looked like this as I was flushing it all out. You can see it getting lighter as the new fluid was flushed through. No telling how long it was in the car, but I redid all the brakes during the track car conversion. Have stainless brake lines now...

 

lol , i wouldnt have put it in a coke bottle lol .

 

update: i got the problem fixed , however i had to take all the equippment off my 85 to put on it , for future refference if you use the hard line you will have to bend it to fit the earlier master cylenders and vica versa for the later ones . the problem was the master cylender , as it turned out it was leaking out the back and down into the interior of the car .

 

Yep, that's where the master leaks when the cups.seals go bad. Be sure to back the carpeting and clean the brake fluid. Sp up as much as you can, then clean the metal floor pan with brake cleaner to stop the fluid from eating the paint and starting a rust spot. Also remove any of the padding that is soaked with brake fluid.

Since the old master, hose and slave has lasted this long, expect as long or longer service life from the replacements. For greater longevity, replace all 3 hydraulic parts to prevent contamination from the old parts.

 

fantastic advice , i hadnt even thought to pull the carpet back. the carpet is prettty shot anyways so it wount break my heart to rip out and throw away lol .
i also found out today that the only difference in the master cylenders is the housing .
