Old Brake Fluid looked greenish.

[Loobed]

I power flushed my brake system this weekend. The old stuff was Castrol LMA DOT 4 fluid, and was in there 2 years. The old fluid looked greenish when it came out. I never seen greenish fluid. These pictures don't show the greenish tint.

I have seen it happen many times to all kinds of brake fluid.

I don't know why it happens.

At least its not black as night and 5+ years old like the brake fluid was in my civic...

You won't like it when it's angry.

Good work. Brake fluid should be changed every 2 years.

Brand new Castrol LMA is tinted green, so that is normal for that brake fluid.

I was about to say that fluid looks pretty good. I usually change every 3 years for the car and every 1.5-2 for my truck and it looks like dark tea.

The factory fill on my 06 Saturn is green. I haven't had time to flush it yet, but it still looks clear!

Two years is as long as you want to go, espeically with DOT 4 fluid. As the fluid absorbs moisture it can get a little corrosive due to free boric acid. The green tint (if it is not dye) could be from some mild copper corrosion.
