Overfill brake fluid

Just been doing my weekly checks on the 110 to make sure nothing is leaking (well nothing new anyway) and had a thought about the brake fluid reservoir. What actually happens if you overfill it? I haven't before you ask but just interested if anyone knows?

nothing but will leak out of cap when you push pistons back when you fit new pads

If you would like the level to be correct then dip a piece of CLEAN rag into the top of the resevoir to soak a little fluid up. Do it until the level is correct.

I use kitchen roll but there is a danger of bits getting in the resevoir off the paper so be very careful, I screw it up until it will go in the top then dip in let it soak for a second or two then remove. Its surprising how much fluid can be removed like this.

The proper way is to use a suction pump, bike pump would do
