Shimano disk oil

[cruisin]

I have just set up an offroad touring bike with shimano disks, and would like to know the specification for the shimano mineral oil in case I need oil in some out of the way place.
I would guess it is some sort of light weight hydraulic oil but would like exact specs if anyone knows them?

Just find a Shimano dealer, and buy Shimano Mineral Oil. It's red, they only make one type.

You can only use mineral oil in Shimano brakes. Don't use regular automotive brake fluid or you'll need to replace all your brake lines and seals... expensive. <erk!> And potentially fatal in the case of brake failure.

However, if you have Hayes brakes you can only use DOT 3 or DOT 4 automotive brake fluid. Use mineral oils and you'll need to (you guessed it) replace all your brake lines and seals.

Read the instructions for your brakes and pick up a bottle of the right oil for your brakes, and a universal brake bleed kit. Brake bleeding is not rocket science - so long as you're careful not to mix up your oils!
