I have some Motul Brake fluid (RF600?) on the shelf. It has been opened many years ago. Prolly like 20 plus. Has not been opened since I used it that long ago and it is in a metal can.

My question is this any good now?

Reason I would like to use it is it is blue in color if my memory serves me right. No other reason. Pure bling.

What say you?

No, any break fluid needs to be used from and up opened and sealed container. Old open cans of brake fluid draws moisture in from the air and make it useless.

Also, you say blue color?

If you are buying new brake fluid look for DOT3, DOT4 or DOT5.1, not DOT5.
DOT5 is silicone-based and it is dyed purple. (The appropriate fluid for MX bikes is clear/yellowish.) This product does not mix with the other ones mentioned above and will compromise your braking system.


Braaapin' aint easy.

I know ATE used to sell a blue DOT4 fluid, but I don't think that's available anymore.

A brake fluid this old is no good.

Don't be cheap on the brake system, it's the only thing stopping you when things go sideways. 10$ is not worth the risk IMO
