Motive bleeder question

[Brian Miller_dup1]

With all the recent trouble that I had bleeding the brakes on our Hyundai, I broke down and ordered a Motive bleeder. It should be here in a few days.

My question is: Do you still need to follow the recommended bleeding order for the brakes, or does it matter since you are using pressure instead of pumping the pedal?

Thanks,
Brian

I always start from the longest line to the shortest. You will really like the Motive. It is very, very easy.

Follow the same order.

Will Motive bleeder flush out all the old brake fluid on ABS brakes?

 

[HEV]

Yes.

I have ordered two sets of Speed Bleeder, but haven't got time to install them. Will Speed Bleeder work better than Motive Bleeder? For the cost of 8 Speed Bleeders (for two cars) I could have bought a Motive Bleeder.

You Do NOT blead brakes by doing the longest leg first. Most ABS vehicles start with the shortest leg first and then it goes what everway the system was designed. If you do the longest leg first you can contaminate the system by pushing old fluid into the rest of the ABS plumbing

How do you clean your Motive bleeder after use?

Good question M.

I have yet to clean my bleeder assist, though I've intermittently put the mating cap to the resevoir in a plastic bag when upon flushing the lines, I found the front rubber's to be cracking. I later used it again after I replaced those same lines.

To clean the unit, I'd imagine a good soap and water flush and air-drying would be fine. DOT 3&4 fluids are eth. glycol products are they not, and readily "dilute" in water thus making it possible to rinse away?

What then would be the recommended handling of the rinse solution in terms of limitting environmental impact - if just b. fluid and water, could it then be added to one's collection of used engine coolant that's to be taken to a hazmat facility? Left seperate or with the collection of used B. fluid that is to be taken to hazmat?

Tech./chem. experts...what's your take on this?

I just clean mine with water. DOT 3-4 brake fluid is water solvable. I just rinse mine out real well, then allow it to completely dry. I’ve done this several times on mine.

In the past I have used a water and dish soap solution to clean my Motive bleeder internals, but I too have wondered about whether or not it's safe to flush the contaminated water then down the drain.

Not on my truck it's not, mine definately is longest to shortest, and it does have ABS, factory manual gives order. some 90's you did in a criss cross fashion, as there was a mid body valve of some sort, but I forget the particulars.

If you are just talking about the residual fluid film sticking to the bleeder...by the time you wash it off, it's too dilute to be a problem.

I see the clean up as part of the more bother than it is worth. The left over fluid must be disposed of, and the unit cleaned up. The bleeder between uses isn't sealed up near as well as a brake system. Any fluid left in it will be collecting water and grit, which you do not want to replace what may be old brake fluid in better condition. I am not sure I would rely on air drying to remove wash water. A methanol rinse would be safer. If you are going to screw around bleeding brakes, make sure you don't cause more problems than you solve.

Actually, after rinsing with water, I do run denatured alcohol through the pump. It dries then quickly.
