Clutch fluid! Help please
While my brother was doing a bit to my bike the other day he had to bleed my clutch and he only added 30mm of oil but he used brake fluid now i am wondering is this a bad thing or or is it fine to mix this with whatever oil is already in there? Cheers Nato.

The brake fluid will cause the seals to swell. You can try draining all the fluid and flush with brake clean.

yep bad thing to do, hopefully the 30ml will not cause too much effect diluted, you need to use mineral oil (5W fork oil works fine!) in the clutch

you don't say what year bike you have. Some years used brake fluid and some mineral fluid. It says what to use on the reservoir lid. You absolutely can't mix the two.

If you mix brake fluid with oil or the reverse there is a 100% chance that all the rubber seals and hoses in your braking system will be compromised or ruined. Depending on how much you got in the system and how long it stayed will determine how quickly all the rubber parts will fail. Not maybe but will fail.
You must flush the entire system with alcohol and then replace all the rubber parts. The residue of oil will keep doing damage if you don't get it clean. Sorry to bear the bad news |

What does the reservoir cap say? I think mineral oil was only used for a couple years (in the clutch only). Think your 2010 uses brake fluid for the brake and clutch reservoir.
And yes, mixing brake fluid with mineral oil will cause the o-rings to eventually swell and fail.

my 2010 300 is mineral oil...I believe like many things with hydo clutches companies changed from time to time and from one to the other. Ktm had many combinations over the years...
