Shimano mineral oil is a suitable brake fluid for
all Shimano hydraulic disc brakes,
whether MTB, Road,
Gravel or Touring.
Since it does not bind water,
mineral oil has the advantage over
DOT of longer constant quality -
you do not have to replace it as often.
A funnel bleed kit for the lever and a basic bleed kit or
professional bleed kit for the disc brake
are sold separately. When servicing the brakes,
please ensure that no oil gets onto the brake rotors.
