staryarm69 Posted February 15, 2012 Report Share Posted February 15, 2012 so heres the thing, a lot of riders use water for a magura bleed as its a better feel mostly because its denser (harder) while what about tank brake fluid? this stuff is about 20 to 30% denser then water. and risk of freezing. has any body tried tank fluid ?

trialsbeginner Posted February 15, 2012 Report Share Posted February 15, 2012 in my head this means like tank as in the huge vehicles with massive guns brake fluid? or am i just and idiot? Quote Link to comment Share on other sites More sharing options...

pogo Posted February 16, 2012 Report Share Posted February 16, 2012 water is used because it has a lower viscosity making it easier to move. Quote Link to comment Share on other sites More sharing options...
staryarm69 Posted February 16, 2012 Author Report Share Posted February 16, 2012 are you messin or for you actually mean it? when you say im right? i mean it mate im talking about 100% British military spec tank brake fluid. im thinking if water is so good and i personnely much proffer it to royal blood then could tank fluid be even better water is used because it has a lower viscosity making it easier to move. i dont know the viscosity of the tank fluid but with it being so hard im thinking it will be like a solid bar in the lines so vary responsive my thought on the draw backs are if the pistons will return at a usable rate 1 Quote Link to comment Share on other sites More sharing options...

pogo Posted February 16, 2012 Report Share Posted February 16, 2012 For the pressures involved in trials both fluids can be considered incompressable and oil is usually classed as less dense than water (oil floats on water) with the viscosity being the ease of which the fluid moves, any spongyness is usually due to a poor bleed or gasses diffusing through the liquid Quote Link to comment Share on other sites More sharing options...
Ali C Posted February 16, 2012 Report Share Posted February 16, 2012 I'm no engineer but..... Liquid is pretty compression-less (note pretty, not entirely), water, oil etc is VERY hard to compress, I doubt tank fluid is any "harder" than water and I doubt you would notice any difference other than the weight saving in your wallet. Edit: that was just talking about how stiff the brake would be, as has been mentioned water works well because it's thinner than oil, if you really want to experiment you need to try something even thinner, mercury could be a good one Quote Link to comment Share on other sites More sharing options...
pogo Posted February 16, 2012 Report Share Posted February 16, 2012 If it's a 'thicker' oil it'd be like using treacle as brake fluid Quote Link to comment Share on other sites More sharing options...

staryarm69 Posted February 16, 2012 Author Report Share Posted February 16, 2012 I'm thinking a experement is in order, sud be no more then 2 weeks and the fluid will be sat here ready to play with, I'm rather looking forward to trying it and seeing how it works and since this is a freebee its defo worth a try Thanks for the comments, its always good to get a dicussion goinIt's hard to remove air bubbles from treacle but does any one know wear I cud get some murcury ?

craigjames Posted February 16, 2012 Report Share Posted February 16, 2012 Do you know what type of brake fluid the tank uses? If it's just some form of mineral hydraulic fluid it should be ok, but if it's some form of DOT fluid then it will ruin your Magura. Might want to check before you go chucking it in an already working brake. 1 Quote Link to comment Share on other sites More sharing options...

Was just about to say that the fact they are calling it "brake fluid" sounds like its most likely a DOT type fluid, and therefore bad for maguras! Water is fine, I am using the coolant we use for diggers at the factory where I work, and its working well, possibly better than my last water bleed!

haydon_peter Posted February 16, 2012 Report Share Posted February 16, 2012 Does anyone want to start a new business with me? We will buy Halfords brake fluid (DOT or Mineral, whichever is cheapest) then we will put it in bottles and put stickers on it saying 'TANK BRAKE FLUID THIS STUFF IS BETTERER THAN EVERYTHING ELSE' and we will sell it on ebay for massive profits!

staryarm69 Posted February 16, 2012 Author Report Share Posted February 16, 2012 in my eyes if u dont look to improve things will never get better n a small improvement in fluid is still and improvement. thanks for mentioning the mineral and dot part i didn't think of that and not sure which it is but will check when it comes (not paying for it so nowt to loose rely) anybody else tried something other then the norm and what was the results like Quote Link to comment Share on other sites More sharing options...
Ali C Posted February 16, 2012 Report Share Posted February 16, 2012 tried a vee brake, found it had advantages over maguras in nearly every bit, so I carried on using it. 3 Quote Link to comment Share on other sites More sharing options...
aener Posted February 16, 2012 Report Share Posted February 16, 2012 tried a vee brake, found it had advantages over maguras in nearly every bit, so I carried on using it. So did I - but I was so bad at setting them up I reverted to a mag The times I got Josh set it up for me it performed notably better than any Magura/Echo I've had, but I don't like having to get other people to set my bike up for me Another vote for Vees rather than tank brake fluid. Staryarm, you made a suggestion which you thought might work. People gave you fairly hard evidence that it will be to oil as oil is to water, and you're going to do it anyway? As you said - it's free so there's not much to lose, but you know it's going to be worse... I'm all for experimentation, but if the theory behind said experiment states it'll be worse than the original we moved away from, it seems like a waste of effort.

JD™ Posted February 16, 2012 Report Share Posted February 16, 2012 Oh, and you do have something to lose - your brake, when it completely f**ks the seals by being a DOT fluid (most likely) rather than a mineral oil. Quote Link to comment Share on other sites More sharing options...
