• Shimano fluid disc brakes, is it still safe to use baby oil in them or is it still lhm/lhm+ or trolley jack oil preferred.

  • Seems a few (claimed) mechanics have done the baby oil and it was fine... But I have done the lhm/lhm+ in the past and has been fine to the best of my knowledge. Now that lhm is expensive (as I have run out) was looking the hydraulic oil used in trolley jacks.
