I've just got a new (to me) mountain bike and the back brake needs bleeding. Shimano M545 hydraulic discs. Does anyone know if the mineral oil the brake system runs is LHM as used in Citroen hydraulics? I know it's mineral oil, also incompatible with regular automotive brake fluid. The Citroen stuff has green dye in it.
I should probably play safe and buy the proper stuff. It's just that being in the motor trade I can get LHM cheap and I'm tight.
