Flushing the brake system on a 99 2500 4X4

I'm looking to do some preventive maintenance on my brake system as in flushing out the old fluid. Everything is working fine, just reaching out to confirm there is nothing special or out of the norm to do. I have a Motion pressure bleeder, plan is to let it idle and start from the furthest rear and work forward. I'm assuming this should be a no brainer, but we all know what assuming does. Any input would be appreciated!

You'd think it would be a no brainer but there's more than one thread out there about someone doing what you're doing and ended up with squishy terrible brakes. I'd just be cautious and be very careful to not allow any air to enter the system.

Thank you Katoom! I understand completely. I can see people using the old conventional way of pumping the pedal, getting in trouble if they're not carful, But using the Motion Pro is much easier for one person as long as it's used as designed.

My flushing turned out great! I used a large syringe to draw all the fluid that I could out of the reservoir, hooked up my brake bleeder with about 1.5 qt of Dot 4 fluid and worked the furthest to the closest. I made sure I had clean fluid at each point which ended up using about a QT. I may do it again in a few months to be sure since while clean fluid was flowing, I would get a short blast of dirty stuff. So I used to be happy with my brake's, I think I now have a better pedal so there might have been a small amount of air in my system. The Motive bleeder worked great and has paid for it self many times over. The whole job took less than 30 minutes.
