I was talking to my brother about his new bike. He was going on about things his instructor said to do. He was talking about his radiator and over flow tank. Then I asked him where his brake fluid tank is and where he puts his oil. He looked confused. I just wanted to see if he could do basic maintenance. So we went out and I checked his oil told him where too put it. Then went looking for his brake fluid tank. It turns out his instructor told him it was his over flow tank and next time his radiator needs filled put it in there. No idea how that would have turned out as I don't know how brake fluid reacts with coolant. But he emailed the dealer for a double check. Then I spent the next 20 mins convincing him the next time he needs his brake pads changed to let me know and I'll teach him to do it.
