What Viscosity?

[JIX]

What viscosity do magura recommend for their brakes?? Its in the manual but I wont be able to check before I go to buy some so if some one could look for me please :huh: i would realy appritiate it.

Also do you reckon if I went less viscious it would be better?

[Siders77]

What is Viscosity? lol :huh:

[JIX]

I spelt it wrong, but it is the thickness of the oil

Which pretty much dictates how well it will move through the hose, and how heavy it will feel.

[RicH_87]

i think you want pretty thin,

no more than dot 3 i think.

[Brian Bleech]

but maguras use mineral oil, which is just standard and does use DOT measurments

I just looked in the Magura Manual but I couldn't find where it said how thick the fluid had to be etc....It just said "DO NOT USE DOT BRAKE FLUID" lol

Sorry I couldn't help you more. :huh:

[AdamR28]

Magura 'official' oil is about 8.5wt.

Water is less than that, and works a lot better (when old oil is flushed out properly).

You can try Finish Line Shock Oil, that works ok too, and goes right down to 2.5wt.

[JIX]

Im going to have to go to halfords to get it, so if you know of anything that they have. I have normally gone for citron car brake fluid which is mineral oil.

Adam do you know the viscosity of water?? I might go for something inbetween.

[AdamR28]

Hellfrauds won't have anything like that - all they have is the Citreon mineral oil, which is at least 8.5wt.

Water? Less than 1. http://www.google.co.uk/search?hl=en&q=wat...le+Search&meta=

PS: Just use water AFTER flushing it all properly.

I think that water has a viscosity of 1.00 because that’s how they define the scale – Everything is given a rating relative to water (I think :huh: ). Apparently, you can get rubbing oil for cleaning brass (Ie. Musical instruments) that is 0.6 wt or something like that – almost half the viscosity of water. So that should be pretty good, if you can get hold of any, although I think it comes in tiny bottles that are about 5ml. Might be worth looking for if you’re that bothered?

Other than that, just use water, or any kind of mineral oil. It doesn’t really make much difference.

[JIX]

if i use water, i would want to put anti freeze in there aswell.

Plus is water any good in the long run? Would I have to bleed it every 6 months?

Does anti freeze mess up the internals?

[Siders77]

I've used water for ages now. Without any Anti Freeze. It's been fine. The only time I had to bleed was when I changed the hose over. :huh:

It's been fine for me.

[rich4130]

My magura is bled with water, I think it was you who reckoned it felt nice? :huh:

I take my magura to bits, clean the piston/lever with WD40, flush the hoses through with it, re-assemple, flush with water and then bleed.

Most of the inside of a magura is plastic anyway so I wouldn't have thought it would do any harm, mine seems fine anyway.

[Rob_P]

Just bleed you feggin maguras with water and be done with it!!

Works a treat and you wont have to go far to get ALOT of it!!

You wont look back!

Rob :huh:

Can I flush the maggie oil out without taking my brake apart? I want to bleed it with water but I don't have an 8mm spanner to screw all the hoses off and I'm not excited of the idea of taking the brake off my bike and setting it up again later etc.

Thanks.

The blue Royal Blood by Magura got a viscosity of 5wt and the green Blood is 8wt.

2.5wt shock oil feels better then the original Magura oils, but water is where it's at :huh:

Yeah, either just pump loads of water through the system, or attach your pump to the bleed pipe thing and pump loads of air through quite fast.

[Danny]

I took mine appart and bled it and flushed it though with water loads of times with water over a period of about 6 months. Yet when i decided to take the piston out the lever it was still full of manky water/oil mixture. Your best bets probably a track pump or an airline.

[Janson]

i used a pump to blow all the oil and stuff out. bleed through a few times with tap water and you'll get the manky crap from the seals off. then just bleed it.

also, bleeding with water is a 5 minute job. also, not messy at all, after all, it's just water!

Get yourself a large syringe (60ml or so) and its more like 1 minute (Y)

[danny B]

I use water in my brakes and so does ben and all the other lads that i know, its really good but the only problem is tha after a while you have to watch the calipers becayse they start to seeze up so you have to service them to keep them sweet. (Y)

[Simpson]

Water has a Viscosity of 1 and i think I'm using clutch oil for Bently's which is about 6 bit spungy but nice and sharp so prob change it soon

as dan said... use water... but bleed it will oil every now and then to stop the seals dying and drying out..

[Janson]

or just wind the tpa all the way in, press the lever fully, press one pad in and drop some oil/lube/whatever onto the seals and stuff, and pump the lever a few times. quicker and works fine.

Try bleeding it wit cooking oil... it makes it VERY VERY slow!! lol

but it lubes up the whole system! and then re-bleed with water again :)

i might take mine apart and blow it through with the compressor :) just to see if my brake goes any fast... oh and i better get some de-ironised water to bleed them with. just to be on the safe side :)
