A couple of questions -
1. Are the front and rear brake systems linked on an ABS CBR250?
2. What is the procedure for bleeding the ABS brake system?

The brake fluid on a CBR250R Combined ABS model has to be changed / bled in a different way as on a non ABS model! It is not enough to do it the common way, only just by pumping.

Take a look at my thread, please:

last I checked your post is linking to another persons oil change instructions and asking the exact same question as this thread, so please tell us, why should we look at your thread?
it's useless.

As you can see: two questions and unfortunately no answer yet. I think not many of us had done this work until now. You are welcome to start, if you have the possibility to do it, unstead of writing attackable comments. I am planning to change the brake fluid when the temperature will rise, now it’s too cold in my place for working outside on a motorcycle.

Where are you getting this idea?
There must be brake fluid in the ABS valve unit, so you have to open the valves and pump out the fluid, which is inside the unit.

ej22tgc8 describes his problem in this thread:

http://www.cbr250.net/forum/cbr250-service-maintenance/1764-brake-bleeding-madness-caused.html

I suppose air has come into his valve unit and to pump it out, you have to open the valves first, for example by short-circuiting the valve unit. If you don't do that you will pump out the fluid and air out of the hoses, but not the ABS unit. Air will stay inside. The same with changing the fluid, the old one will stay in the ABS unit.

But that is only an assumption and I won't give anybody advice how do do something if I am not 100% sure, and that's the case here.

I hope someone in the forum knows how it works and will write it.
