Did you put a lid on it when you put it away?

 

If it's left open its junk. Brake fluid absorbs moisture.

 

I have a couple of half bottles like that. From what I have been reading on dealers working on brakes system issues lately, the "new" procedure to to use huge amounts of fluid to really flush the system. On my next flush (never had a brake problem) I am planning to use all my old fluid to flush, then flush that out with a new bottle. So, in a way, I will have put the unused fluid on the shelf to good use, before throwing it out. YMMV.

yes

it true. once open that's
it why take a chance on contaminating system it cheap enough

 

brake fluid

Brake fluid is hydroscopic. Meaning it absorbs moisture. Once a can of brake fluid is opened, it can be easily contaminated just by absorbing moisture from the air. I would never use an old can of opened brake fluid.

Stay away from the Honda fluid unless the dealer moves a lot of it. A friend picked up a bottle so I could change it on his bike. It was a foil sealed bottle, and when I opened it, it was darker than the stuff I was going to take out of the bike. I just get it at Wal Mart because the move it pretty quick. Make sure you get DOT 4.

The OEM Honda fluid has an orange colored dye added to it that makes it look darker.

Why the heck would any manufacturer go to the trouble of making their brake fluid a "color"? That doesn't make any sense.

Thanks Fred, Did not know that. I have taken out 4 year old fluid that was as dark as this stuff was.

 

2 years with the cap on works for me its its older than that i toss it out :thumbup:

To make it easier to determine the level in the reservoir.

 

Kinda wondering, if Honda adds dye to their brake fluid, why don't they make it a color that doesn't look like old brake fluid. You know, something like blue or green. Making it "orange-ish" makes it hard to tell if it's old fluid or Honda's dyed stuff.
Maybe it's a marketing ploy to allow their mechanics to say "see...your brake fluid is dark and should be replaced....that orange color means it's bad".

 

Keep the bottle as full as possible

The trick is to have a couple size bottles of brake fluid around the shop so that you can put what's left over from a bigger bottle into a smaller bottle for storage.

You want as full a bottle as you can get when you put the cap on it to store it. If the bottle is nearly completely full, there is very little air left in the bottle from which the brake fluid can absorb moisture. It will keep for a long time that way.

Conversely, you don't want to let a quart bottle that's got just a few inches of fluid left in the bottom sit on the shelf for very long, even with the cap on.

Kind of the same issue as storing gas in your gas tank for a long time. Keep it as full as possible so there's little air in it.

It's colored to give contrast. Usually the aftermarket stuff is clear and clear make it difficult to see how full the rear master cylinder is. Also, the Honda brake fluid has a long neck on it so filling the rear master cylinder is easier.

 

The rear master reservoir has marks on it if filled properly. A good mechanic knows that a little flick and you can see the fluid level through the reservoir.

Honda isn't to only company to require a dye in there branded brake fluid.


Most I know use Valvoline synthetic because it exceeds Hondas requirements and has a higher boiling point. which is beneficial for those who ever had a brake shudder.
It doesn't cure it.it just prolongs its return after a proper brake fluid change.

 

not gonna quote but there is some misinformation here as usual. Do your research!!!!!! Pros who race can give you the straight skinny.

Easy way to tell what is leaking all over the place, is why anti freeze is green (used to be) ATF is red, oil is slightly brownish.....

I wouldn't drink it tho

Lid on it should still be Ok. I would use it in the car..
