we just bought a 06 325i. the brakes were a bit mushy so i had a BMW mechanic replace the rear rotors and pads and he said the fronts were fine. also had all the fluid bled as i was figuring air in the lines. he said that he bled them for almost 2 hours and he thinks there is air in the abs and that BMW can open up the ABS and flush that as well. so 160.00 later i took it to BMW and they said its the master cylinder. i found a local BMW shop that has all the computers and had the master cylinder replaced. still same thing. now they are thinking its the actual abs system/computer and the rear brakes are not engaging. anyone have any experience like this.. we have done all the obvious and have not gotten anywhere. the car only has 106K on it and seems very solid but this brake thing is killing me.
