TonyB Posted November 22, 2006 Report Share Posted November 22, 2006 Might be a stupid question but I was wondering why hydraulic brakes use mineral oil instead of standard brake fluid (like Dot 4 or Dot 5). I can only think that brake fluid would corrode or damage some of the components on Maguras or whatever. Anyone know the answer?Tony Quote Link to comment Share on other sites More sharing options...
T-BAD Posted November 22, 2006 Report Share Posted November 22, 2006 you answerd the question your self if they could use dot 3-4 they would, its alot thinner then mineral oil so the brake would feel alot better... tonyb? tony blair?

nmt_oli Posted November 22, 2006 Report Share Posted November 22, 2006 Magura and shimano systems use mineral oil, while others like Hope and Hayes use Dot fluid.Mineral oil could be considered the better fluid, as it has better lubricating properties, and is not hygroscopic, so does not need to be changed anually to keep it at its best.The brakes that use dot fluid tend to be from more 'industrial' companies or ones from a motorbike background.What fluid it is doesnt make much difference to the feel of the brake, but you must use the correct fluid in the correct brake, otherwise parts will get damaged- mainly seals.
