I had my right rear caliber seize. I removed the old caliber and took it with me to get the new one. Long story short I had a ton of brake fluid leak out before I got back to put the new caliber on. I good bit of the brake fluid came out and the resevior was almost empty. I put the new caliper on, put fresh fluid in the resevior and began to bleed my brake system. I did all 4 lines starting with the passenger rear. I bled for about 2 hours last night, both gravity and suction pump. My brake pedal is still spongey.

My question is how long does it take to get air out of the line bleeding it yourself either by gravity or suction pump and can you get all the air out or do you "have" to get the dealer to do the ABS pump bleed?

 

You need to run the abs, I bet the reservoir went dry, which means the pump did.

My suggestions is, if you CAN SAFELY drive the vehicle. Maybe just outside of your neighborhood or something, do so. Do several panic stops and try to get the abs to operate. Unfortunately you will likely need to bleed air out of all four wheels and do this procedure a few times.

It would also be best to do a "two-man" bleed while doing this. (I'd do it in the road if you can get to an industrial/empty area)

 

As mentioned earlier, you probably have air trapped in the ABS pump or even the master cylinder. If you have a local chain brake shop or Jeep dealer nearby, I would drop it off and have the the fluid replaced which would of course involve a complete system bleed. After replacing various brake components on my old ZJ I ran into the same problem. I did a manual 2-man bleed which helped but still wasn't quite right. Went to a chain brake shop and $100 / 1 hour later I had new fluid in the system, no air, and solid brake pedal.

In the meantime, I would avoid highways, high speeds, and situations that would cause a panic stop until you have a consistently comfortable pedal response.

Best of luck,
John

 

Is there a way I can get the air out of it or is the dealer/brake place the only way? I'm about 20 minute highway drive from the nearest place.

 

u might be able to get the abs pump to work by jacking all 4 tires off the ground, then put it in first and drive wheels SLOWLY... the differences in wheel speed due to being off ground should make the abs pump work.. then just keep bleading the brakes... after u stop and turn engine off.. lol..
or... just jack the back up and run it in 2wd.. that should def make the pump work cause the front wheels will be stopped.. keep esp/trac on.

 

It's not the only way but it's the safest bet especially with our braking system. The pump has several internal circuits and solenoids and trying to clear all the air in your garage will be very difficult and frustrating. The dealer or a brake shop will be able to actuate the pump in the proper sequence to evacuate all the air. Plus you end up with new brake fluid!
