Frozen Brake

[Andeee]

Ive ran the same rear brake for the last 5 years. Original oil from manufacturer. No pops or leaks yet (touch wood) I see no point of using different forms of fluids as you just know its gonna freeze in winter then wreck the insides of your seals.

If you read the thread, you will find plenty of reasons to use a thinner fluid. You will also find that if you do it properly then there is no reason why it ever needs to freeze or wreck your seals. There is a reason why so many top riders use it! I was really against it for years and thought I knew better, but I'd hate to have to go back to oil now.

I use water and anti-freeze mix which is protected down to -20 or something silly, it works great all year round. The only problem I get is sticky pistons every few months which need lubing. But that is probably down to fact my brake had had 5 years of hard use and usually has the TPA wound in.

The only reason for trying the emulsion fluid was to eliminate my sticky pistons, water/antifreeze alone doesnt lubricate the seals sufficiently and the emulsion solved that problem 100%

Matt, next time you bleed just put a couple of squirts of oil in there with a spot of washing up liquid (Ive got a bottle premixed that I give a quick shake and fill the syringe from). Feels identical to water but no problems with sticky pistons, my slaves are now over 12 years old and working fine

But still your having problems? Magura blood For The Win i suppose?

Nope, water 'for the win'.

I dunno I've never had any problems with water for over 5 years now, brake froze once in Belgium and was fine for a comp after it thawed.

I'd rather have to lube the pistons every few months than suffer arm pump while riding when there is no need to suffer excessively.

Dual Hopes don't freeze.

Almost all 'normal' types of anti-freeze have corrosion inhibiters in them, which should theoretically sort that. I don't recall having any issues when I used anti-freeze with mine.

Just checked the bottle we usually use and it says in it that it's got some in it. Think it's "CarPlan Blue Star" or something like that, was like a fiver or something for about a litre. (EDIT: Or £8 for 2 litres at some random shop online.)

I wouldn't know, i've still never used anti freeze in winter. Only ever had the brake freeze up 2-3 times, usually when left outside. Seems fine in the garage currently though so i'm not going to bother again this year.
