hayleyearth Posted October 30, 2013 Share What fluid does your car brake system work on? I have dripped DOT on my paint several time and just wiped it off, this was over 2 years ago and the paint is still on? When Rouxtjie started speaking about DOT I thought he was refering to that dot system people now use to track and trace things (I thougth maybe some people would want to do that due to the price of Hopes....expecially the ones with the green you know) just shows you how little a woman knows about lubricants .....

SomeBloke Posted October 30, 2013 Share Yup. I can also confirm that dot5 is not that corrosive. I poured about a litre of it on my bike and the floor. It also doesn't damage phone screens. I poured half of it on my iPhone trying to watch the YouTube video while I did it. YUMEYA, Peach., ThePubSA and 1 other 4 Link to comment Share on other sites More sharing options...
G00SE Posted October 30, 2013 Share Brake fluid has been paint friendly since DOT 3.5.... and you are really going to have to look for DOT 3 fluid that is not paint friendly. Brake fluid is NOT pad friendly - neither is mineral oil.... First bit of useful info in almost 10 pages. Interesting, I never knew that - I'm not going to test it though, luckily I have shitmanos. I do know about both fluids being unfriendly to pads though - first hand experience Link to comment Share on other sites More sharing options...

rouxtjie Posted October 30, 2013 Share Why would anyone leave a drop of oil on anything it is not meant to be on?you know if you leave a drop of sunlight on almost anything it will also damage it!Well that is really the thing, I like ghetto bleeds...its quick and easy, requires a bit of finesse and oil will go all over your bars and levers...quick and easy no need for special clamps and sheet. Dot goes in everywhere, eats pretty paint and makes the anodising look kuk, mineral oil keeps everything perfect. But the real dealbreaker with dot is its love affair with moisture the rest I can bear. Link to comment Share on other sites More sharing options...

V12man Posted October 30, 2013 Share But what if you get- Heavy x fast- light x super fast then Shitmano's die Heavy x Fast would have crashed long before he reached anything approaching brake ICU... let alone mortuary... Link to comment Share on other sites More sharing options...

I do know about both fluids being unfriendly to pads though - first hand experience First hand experience on this (used sram dot 5.1 for avids) couple of drops landed on the frame, sat there for about 1 hours while I busy trying to bleed the stupid avids(that is a different argument but anyway). Wiped it clean afterwards. Paint peeled from that spot a week later...noticed it while I was washing the bike. I repeat...dot whatever....never again Link to comment Share on other sites More sharing options...

DOT = Department Of Transport See:http://www.stoptech.com/technical-support/technical-white-papers/brake-fluidhttp://auto.howstuffworks.com/auto-parts/brakes/brake-tests/how-to-check-brake-fluid2.htm What Is DOT In Brake Fluid? Brake Fluid Type Nature Dry Boil Temp Wet Boil Temp Color Common Uses DOT 3 Glycol 401 F/205 C 284 F/140 C Colorless to amber Passenger cars and trucks DOT 4 Glycol 446 F/230 C 311 F/155 C Colorless to amber Passenger cars and trucks DOT 5 Silicone 500 F/260 C 356 F/180 C Purple Military and show vehicles DOT 5.1 Glycol 518 F/270 C 374 F/190 C Colorless to amber Racing cars [source: AFCO, USDOT]If you dig deep enough into any subject, you'll find controversy. Brake fluid's big issue is whether to use glycol- or silicone-based brake fluid. They don't play well together, so knowing which one to use is critical for the performance of your brakes.On the previous page, we learned that your vehicle's brake fluid reservoir has instructions on what type of fluid to use. Brake fluid is referred to by its DOT number and can be any of four varieties, though most passenger cars in the United States take either DOT 3 or DOT 4. The DOT part refers to the U.S. Department of Transportation, which issues detailed standards for all motor vehicle brake fluids in the country. Federal Motor Vehicle Safety Standard No. 116 details three different classifications of glycol-based brake fluids, and one silicone-based brake fluid (SBBF) [source: USDOT]. DOT 5 uses silicone instead of glycol, which is now the standard for most military vehicles. For race cars and show cars, you'll want to go with this type because, unlike glycol, it won't eat the paint off the car.Beyond that, what's the big difference between the four categories? The answer is twofold. First, there's the boiling point. The higher the DOT number, the higher the boiling point. Remember that temperatures at the can reach up to around 800 degrees Fahrenheit (426.7 degrees Celsius). While it's important to note that these high temperatures are only where the wheels make contact with the brake pad (not in the brake fluid itself), some of that heat is being transferred into the fluid, which needs to be stable in order to function.The second part of the answer is about water. Glycol-based brake fluid is hygroscopic, meaning it readily absorbs moisture found in the air. This is good in the sense that you can't keep moisture out, so it's designed to absorb the small amounts that reach it and still do its job. The downside of this is that the more moisture in your brake fluid, the lower its boiling point. Silicone-based fluid does not absorb water, but rather separates out the denser water and lets it settle to the bottom of your master cylinder, leaving the brake fluid to operate in its pure form and keep its boiling point high.

Peach. Posted October 30, 2013 Share Im showing serious restraint here you are clearly using Hope's or Avid's if they can stop you.This H-Earth chick keeps on digging a hole for herself Link to comment Share on other sites More sharing options...
