Good Afternoon,
I just put another motor in my wifes 2000 Sebring....When I did this I disconnected the front brake lines at the capliers.....and left the ABS pump in the car.....and didn't touch the rear at all....now I can get the front to bleed ok.....but the rear shoes go out and then go back in with the pedal depressed....I have a loud whooshing sound at or in the ABS pump while depressing the pedal.....I've blead these several times now....replaced the master cyclinder and both rear wheel cyclinders... no leaks......Could there still be air trapped???? If the ABS pump is bad is there a somewhat painless way to remove it......Thank-you for Your Time and Efforts

Are the red BRAKE and yellow ABS warning lamps on? If so, a fault code may be stored in the ABS module.
A 'whoosh' almost sounds more like a power brake booster noise, is the vacuum sealing o-ring between the m/cyl and booster in place?
If the shoes go out and then fall back in, it does sound like an internal leak in the HCU of some kind.
Is this a Sebring coupe (FJ-body) or Sebring convertible (JX-body)? Two very different cars.

ImperialCrown, thank- you for your reply..... Sebring Convertible.....no lights on dash.....whoosh sound is at the ABS pump and reverberates thru the rear lines.....pretty crazy......have tried bleeding the brakes several ways with vacuum and without...all is well at the master cylinder and booster.....all fittings are taped and tight......don't really want to drop the subframe again if i don't have to... do you know an easy was to remove the pump from the car......or better still is it possible to clean the the 3 ports for the rear brakes....This sebring hates me but my wife loves it ....200,000 plus on it ......body and interior are very nice.....it's been a great car for her..sooooo....but nothings easy, right.... again thanks for your reply...

These ABS units are difficult to get at and service because of their tight location. Hopefully this isn't a pump problem requiring replacement.
Is air coming out the rear lines?
I know that the DRB 3 scan tool has a sub-menu for bleeding the HCU (hydraulic control unit), but it should be able to be done manually, it just takes a special method and time. Any trapped air will need the solenoids held open electrically to allow the air passage out of the HCU and out the bleeders.
