Alternative to shimano mineral brake oil?

Posts: 55
Just wondering if there is a better value option than the shimano branded stuff? need to shorten the hoses on some deore 595 brakes and i'm guessing they'll need a bleed afterwards but it will hurt me to pay 10 quid for 50 ml of oil.
Many thanks

Am I correct in thinking that any mineral oil for brake systems is fine? or are there some that are not recommended for bikes?0

I'm guessing it needs to be the right viscosity.

No particular brands. But just wondering if I go into a automotive shop and buy the cheapest hydraulic brake mineral oil they have will it be fine.
I know that some car brake cleaners may not be suitable on bike brakes so going along that line ....0 -

I can not think of any cheap automotive brake fluid that is mineral.
in fact i can not think of any automotive brake fluid that is mineral.
except for some Rolls's"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Ok im confused :? I assumed the Citroen stuff you recommended was automotive brake fluid.

Most motorbike or motorcross shops will sell you a small (about 125ml) bottle of mineral oil for less than a fiver.
A lot of bikes, especially dirt bikes like KTM's, run hydraulic clutches which use the same stuff so it's pretty easy to get hold of. Decent brands are Silkolene, Motorex or similar.0 -
have you tried your local bike shop. got a 250ml bottle for a fiver of some generic stuff.0

And here in SRAM land I get 1 litre of Dot 4 for a fiver and flush that bastard every month. Just something to consider if you're ever planning to change brakes.0

DOT 4 is glycol, so will destroy Shimano brakes anyway.
In case anyone is tempted and confused.I don't do smileys.

Shimano uses mineral oil which is the same as LHM as used in Citroens, Rollers and quite a few other cars. Shimano stuff is red, LHM is often green. The colour makes no difference it's only a dye.
DOT4 is glycol based brake fluid, it's hygroscopic and will strip paint so clean up after use.
The two are not compatible use the one appropriate for your braking system. DOT4 can be mixed with DOT3 or DOT5.1 if necessary. DOT3 has a lower boiling point, 5.1 higher but it absorbs more water and goes off quicker. DOT5 is silicone and cannot be mixed with any of the others.0 -
Not that being hydroscopic is an issue in a sealed system like that on an MTB anyway.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

True, but the comment was more aimed at the person flushing their brakes monthly for some unknown reason.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0
