Just bought this new MC, can I use DOT 5? Replacing all the lines and hoses this weekend. I just don’t want a brake fluid that can eat my paint.
I have heard that the 5 don't mix in with the rubbers..When we put DOT 5 in due to the MC leaking and ruining paint, it mixed with DOT 3, no issues. Dad n I simply kept topping up with 5 while we bleed out the 3.
I have heard that the 5 don't mix in with the rubbers..
Cool Man! Just going by what I read... heck, I've been prescribed 2 of the same rescue inhalers, in the last week, from 2 different Dr's, both don't mix with my Beta Blocker... and the inhaler Raises yer BP and pulse! I just switch em up, time wise.. So maybe the book ain't always right! LolZeros issues so far, 12 years and counting...give or take.
I havent checked fluid in over 4 years, that's how long mg its sat.I'll pop the lid off this weekend.
That's why we don't use em on a Scoot!I looked into this issue and rebuilt my calipers and master with DOT 5 for assembly lube. Will be running the complete system on DOT 5. Dot 3, 4 and 5.1 absorb moisture from the air, where as DOT 5 (silicone based) does not.
The thing I have heard about it is if moisture gets into the system it tends to collect on a low spot. Rather then being dispersed into all the fluid.
Personally I'm not too worried if your system is properly sealed.
