Something strange happened to my new clutch fluid, I have a theory but would like everyones input Options

Hey everyone heres the backstory:

upon taking my 99gt our of winter storage, I gave it the once over to prepare for the thousands upon thousand of miles i was going to rack up this summer. I changed the oil, checked all the fluids/filters/plugs ect and everything seemed to have held up very well. The car ran like new
From there i drove the car around all day and there were no issues whatsoever (even after several light thrashings on a twisty road in my area). The following day I was coming back from my friends house and my clutch pedal stuck to the floor. uh oh there goes my slave cylinder, or so i thought. It ended up being my clutch master. I changed both. I also bled the whole system about 4 times thoughout the the whole troubleshooting process. In the end the celi swapped gears effortlessly again

on to my question:

the fluid i filled the system with was DOT III CLEAR fluid (as stated on the master cyl cap). now however, this clear fluid has turned a fantastic shade of brown


compare this with my brake master cylinder where i used the same brand around the same time i did my clutch ( i was on a roll)



nice and clear

so why would the fluid in my clutch system turn brown, while the fluid in my brakes stayed looking like new?
at first i thought that it may have been some gunk inside the lines that has since broken up, but that doesnt make sense since i bled the system FOUR times. should be as clean as it gets in there

could it possibly be that the master and slave cylinders are wearing in, thus dirtying up the fluid a bit?

input and opinions are appreciated

Hey everyone, I'm bringing this thread back because I still have the same issue and have been doing research on what could possibly be the cause

1: It seems this occurs across all makes of cars and bikes too.

2: Some people assert that the brake fluid reacts with low quality aluminum to produce a dark color (has anyone heard something like this?)

3: Fluid turns black when exposed to moisture.. (i poured water into a glass of fluid and watched it over 3 days. nothing happened to it)

4: Heat from the engine causes the fluid to coke (Id imagine this would be a problem for motorcycles more than cars...)

5: cheap seals within master and slave cylinders are wearing away. (definitely possible, but wouldn't that cause and internal leak? and my clutch works great!)

anyone care to troubleshoot again??
