Brake fluid flush questions

I figure with about 50K miles on the odometer, it's time to flush the brakes (they feel a bit soft)

1.Inspecting the brake fluid reservoir, there doesn't seem to be an easy way to get the trusty turkey baster deep enough to suck out some old fluid because of the baffle / mesh thingy. Does that come out ? Or do I need to snake a piece of pipe in and use a pump to suck some out
2. No real level markers on the fluid reservoir. How would I know how much fluid to replace (short of marking the current level on the reservoir and refilling upto that point) ?

Thanks

The little bit of fluid that is in the MC, that you want to take out with the turkey baster is not worth fooling with. A few extra pumps will remove that while chasing it out with fresh fluid. A hose on each bleeder hung in a container with fluid works well but you will need the wheels off. A pressure bleeder works best but not many people have them.
Thanks
Why would I need the wheels off (considering that I can reach the bleeder nipples with the wheels on). Is there something else I would need to access ?

Performed the flush this evening as per procedure using the old school Gatorade bottle method rather than using a vacuum bleeder . Only place I messed up was doing both rear brakes before the fronts . In any case , I got clear fluid out of all bleeder screws at the end so it's all good .

The old fluid was medium amber / honey colored as opposed to the clear / pale yellow new fluid ( I eventually decided to use DOT 3)

Feels a bit better than before + mental peace of mind knowing that it's been taken care of.

For what it's worth , I used a harbor freight pneumatic bleeder to suck some old fluid from the reservoir and also the inverted fill bottle from the kit as a fresh fluid reservoir.

I used 3/16 fuel line hose feeding into a bottle of old fluid powered by pumping the pedal for the actual bleeding process .
