Last service the guy changed all the fluids, since then I've had a problem with the rear brake, had it bled again (twice) no brake unless you pump it. But if I grab the front brake when moving the rear pedal stiffens and if I apply a bit of pressure on the pedal I can release the front and still use the back brake until I release the pedal, then back to normal no brake!
In this case it sounds like the tech, all techs are not equal, let air into the system while changing out the fluid. My tech says that is POSSIBLE to get the air out of the system without cycling the ABS pump(s), but it will take A LOT of fluid and time. Definitely let you dealer service manager know about the problem. They either need to retrain or remove that tech.
