I was bleeding with a Motiv and got to the FL corner. I let the resevoir get empty. I refilled and rebled that corner til no bubbles came out. Is that it, or will I have air throughout the system now?

Probably, will take a while for the air to get to the rears now.

You might have to bench bleed the brake MC. Little air bubbles love to hide there.

Kyle

Feel your pain [banghead]

Wouldn't you be able to tell by pedal feel? Is the pedal "hard" or "mushy". If "mushy" you have your answer .....

Regardless, I would blow the $30 on brake fluid to try and flush all the lines.

I'd bleed all 4 corners again to be sure. I've had this happen before thinking I was just doing a quick bleed and didn't want to put fluid in the Motive tank. It's easy to run the MC reservoir dry if you aren't constantly watching it.

Yah, normally I fill the Motive, but I was being lazy.

Chris, we'll see friday how it feels.

Yup [Big Grin] See you Friday.

FWIW, I never fill the Motive - just too much hassle and waste of fluid, easier to fill reservoir on car and make sure to keep an eye on it - although, obviously this method has its risks .....

Kyle, bleed the whole system now.

I'm with Chris. Just use the Motive to pressurize the reservoir. Less mess.

Motive shmotive. I have one and don't use it anymore. I've used the motive, mighty vac, speed bleeders, etc. Ended up going to the old tried and true method of using a bleed bottle and pumping the pedal. Just watch the reservoir. Fill it after each corner. It only takes about 4-5 pumps to get the fluid through any one of the lines. If you use the bottle right, you will never get bubbles in the system. BTW, a motive will not work with speed bleeders.

For "problem" bleeds I have resorted to gravity bleeding 10/15 minutes per corner. JUst open the bleeder and keep a hose in place. Driver QUIT complaining after!

I have had people tell me to get the left rear corner as high in the air as possible. Because of the bends in the line that goes to it air likes to get trapped there. Any one else subscribe to that belief?

I heard that the right rear was actually the farthest away from the reservoir.

I've got the bleeding thing down, but how do you get the driver to quit complaining? [banghead]

Measure the actual length of the rear brake lines and let me know what you find. With the junction block next to the right rear wheel it stands to reason there is more distance to the left rear than the front.
