While driving approaching stoplight brakes would not engage. Pressed brake pedal to floor and drive van up and over curb while using emergency brake. Contacted dealer where van was towed. Said brakes needed to be bled again. Brakes bled and pedal still felt the same-spongy. Told this is normal. Driving home on winddy road,applied brakes nothing happend released brakes and tried again and the front brakes locked up. Dealer said to bring back. They inspected system said bad master cylinder. Replaced master cylinder and still spongy brakes. Dealer said this is normal. They still do not grip as strong despite all brake components replaced except for the vaccume booster and ABS module. I also no longer hear the ABS module come on like it used to before all of this, the ABS light does come on and goes out after starting van. The owners manual states you should hear the ABS pump come on when starting van then come on again at about 7mph. It does not. Told dealer this and they said the manual is wrong and that the brakes are fine. Yeah, right. When going 55 MPH down hill van would not slow down unless I hold the brake pedal almost all the way down or use the emergency brake and come to a very fast stop. As this being a family van we a scared to drive it. Other mechanics came to conclusion the ABS is at fault. Possible air in chambers and has to be serviced by dealer computer. Dealer says the ABS is fine. We have also found recall on ABS, but our van is not included according to g.m. Please help us get this resolved!! Thank you
