Hey guys, I have been struggling with this off and on for a while now and just stumbled across this forum. When braking on my 86 325es the pedal goes almost to the floor and if I let up and push back down, I have a full pedal. The abs light never comes on (except before I start the car while the ignition is on) I first thought it was the master cylinder, put a new one on, no change. Also has new stock pads and oem brembo rotors. I read somewhere that a bad "accumulator valve" in the abs unit can cause this. Any ideas? Anyone got a used abs unit?
Thanks,
Rick Cooper
