Default Motive Bleeder Question

(Possibly dumb) Question for you experienced Motive users: When I'm finished bleeding and want to remove the fitting from the m/c won't the m/c reservoir be filled right to the rim with fluid? How do I get that fluid level down so I don't spill it all over the place without going too far?

The instructions on the Motive webpage say to 'watch' the fluid level in the reservoir, but obviously that won't work with my C3.

What? You don't have x-ray vision to see through the cast iron?!?!

Heres what you do: first tip the jug so that the remaining fluid can't be expelled to the MC, then go back to a caliper in the front and crack it open for a few seconds and then go to a caliper in the rear and do the same thing; this will lower the fluid level in the MC.

With it tipped, watch the air gap in the clear plastic hose til the last of the fluid gets to the master cylinder, bleed a few seconds more and stop.

i use only air and never put fluid in it.....i measue what comes out and when i hit 4oz i stop and refill the mast cyl....it is kind of a pain but there is no mess.

although i may try those last tips they do make sense

Heck, I just use a syringe or the wife/s turkey baster and suck out any extra fluid from the M/C. Note, new turkey baster needed after the job.

There is some risk in that approach if the brake system is not pretty full, because 4oz might flow into lines and calipers but not appear at bleeder for a while....so you might be pushing air into the system after fluid before 4oz has appeared at the bleeder. You need to be very careful with your method. It would be real nice if Motive bleeder had a see-through cap!

The baster is now part of my kit.

Great tips. I will have to remember this one. I could not figure out what to do with the extra fluid in mine. So the next time I used the method Bob explained.

well i suppose this method has its limitations if the system is not full.....i use this method once a year for annual maintenance bleeding..and i do top off the mst cyl before i start it...if you were putting fluid in after a rebuild i agree this would be too long of a method to use and may be problematic...however on a car that you know the history of and the brakes are working this is a great method of doing it.....4 oz doesn't even come close to the bottom of the mst cyl
