DIY (with pix!) -- Brake Fluid Flush Fandango
I gotta say, the 'Motiv Power Bleeder' *IS* the way to go.
This was my first time using it, and, it IS worth it! You can 'control' what goes on, you DO NOT need a 'buddy' pressing on the brake pedal whilst you're out of ear-shot twiddling with the bleed-screw!
Before 'attempting' this, I did a lot of reading -- esp. the "DIY section(s)", obviously -- however, none of the material I perused had any pictures!
So, here are mine.
FWIW, I was starting to notice a certain 'mushiness' in the pedal travel. The brakes would 'stop' the car, but the pedal would slowly keep on moving towards the floorboard and had the consistency of 'soft cheese'. If I 'pumped it' -- it would get hard but would never stay hard.
Normally this means air needs to be bled from the brake system, but, in my case, a 'full-flush' needed to be performed. Reason? the fluid is required to be _changed_ every two years -- and according to my maint. records... the time was 'now'.
Enjoy !

BTW, this whole 'flush' scha-bang took me approx. 4 hours. Why so long? Well, I was on my own in the driveway in 29 deg. weather with gusty winds and it was my FIRST time! Plus, I had heard that you can do the fronts by merely 'turning the wheels' to one (extreme) side. Frankly, I could NOT seem to get enough access -- so I decided to also take those wheels/tires off too.

Excellent pictures and notes. As an FYI, I also use the Motive (Black Label) and decided not to fill it with fluid. One less thing to clean and no chance of introducing older fluid back into the system next time. I simply top the reservoir off with new fluid (after sucking as much of the old out first) and then pressurize the bleeder. This has worked on a few occasions without a hitch. When I'm done, I just stow the bleeder back in the box - it's still clean as new after three or four uses.

The cost is FREE, you just need to get it there. Check your area for the same.
BTW, nice DIY. A few questions:
1. Did you find that waxy crap ONLY in the float or was it in the reservoir as well?
2. Did your calipers bleed without a fight or were they plugged?
3. Is it safe to start the engine while the car is jacked up??? What do you have to watch out for???
4. Where does the ABS fluid go and how does it get there???
Thanks.

Would you bleed the clutch slave before or after brakes?

2> All 8 nipples bled without a fight but the two rears definitely needed some 'encouragement' before the fluid would 'really' flow. So, instead of increasing the PowerBleeder pressure, I repeatedly 'tapped' on the brake pedal -- which definitely made the crud 'move'. Kinda like kick-startin' things!
3> I had no problem starting the car for 10 sec. or so with one side on the jack.
I just didn't get IN the car ...merely put my hand in thru' the window.
4> I had read that it's a good idea to turn on the ignition/start the engine so as to get fluid going thru' the ABS system - pumps - valves etc. Supposedly the action of actually having the engine _running_ ensures that EVERYTHING gets flushed thru' with new fluid.
Do note, tho', that although the little resevoir seems to hold only a small amount of fluid -- I actually went thru' TWO litre cans of fluid before there was clear blue 'everywhere'. So, if you are thinking of doing this DIY ...make sure you have some 'extra' fluid handy. Just don't open the (sealed) can until you actually do need it.

i) if your fluid is still 'in date' and all you want to do is merely bleed the brakes then I would also ONLY fill the resevoir up to the top and use the the 'Motiv-PB' merely for its 'air-pressure qualities'.
ii) if your fluid is 'out of date' and/or no amount of bleeding is removing the 'squishy-cheese' syndrome from your brake pedal -- then I vote to fill up the 'motiv'PB'. Reason? You are FLUSHING ...not just 'bleeding' and the 'motiv-PB' will empty FIRST before your resevoir does. (And we all DON'T ever want the resevoir to go dry ....right?)

I'll suggest that if you are going to do a complete flush, use some cheap fluid through the system first, then after the fluid runs clean, use the good stuff to finish the job. Different color fluids help to see when all the old stuff is completely flushed. A lot less expensive than just using the good stuff during the flushing stage. As you found out, you can go through quite a bit of brake fluid doing a flush.

"Estimate approximately how much fluid you're going to need and triple it!!!"
With that in mind, I also like the idea of initially flushing with El Cheapo brand (as long as it's DOT 3 or 4 and new) and following up with the good stuff.
Thanks again.

I have the Motive at home too but haven't got a chance to use it so I am not sure how the unit works. So my dumb question is, where do all the air in the tube go when you transfer the new fluid to the resevoir?
Thanks.
Thanks.
