Hayes 9 fluid
Is it true that i need some kind of special fluid for these, or can I just use mineral oil? all of the threads i've seen say either one or the other, and im not sure.
Do not use mineral oil in a Hayes system. All Hayes brakes use DOT 3 or DOT 4 fluid.
Here is a link to the Hayes nine manual.
Also, let us know where these threads are saying to use mineral in Hayes - we gotta correct that.....
Some manufacturers do use mineral oil - Shimano and Magura (ok, they use their own "magura blood" which is essentially a mineral oil).
