[racergt]

yo tuners is it normal for yur brake fluid in yur master brake cylinder reservoir to be black in an old car with a lot of mileage or in any car for that matter?

[toyolink]

No,unfortunately many don't know that brake fluid should be bled-out and replaced at intervals.

Black color is from rubber seals breaking down

^ true.

its possible with a flush to cause the rubbers to further deteriorate.
