Two vehicles in front of my car on highway came to a stop; I applied brakes, pressing all the way to the floor of the car, and nothing happened - the car did not slow down and the ABS did not engage, despite there being loose sand and salt on the road surface. I rear-ended the vehicles resulting in substantial damage to my car (over $10,000 to repair) and the car I hit (unknown cost covered by my insurance company). My car spent 2 months in the shop having the accident damage repaired. When I picked it up, I tested the brakes and they were very "soft" - I had to press the brake pedal all the way to the floor to get the car to stop, even though I was going no more than 10 mph. The ABS did not engage that time either. I returned the car to the dealer to fix the brakes. They kept it all day and told me that nothing needed to be done. However, when I tested the brakes again, in the same spot I had tested them before, the brakes worked well and the ABS engaged. On October 31, 2003, the dealership (bernardi Audi, 521 worcester road, natick MA; 508-651-9980) serviced the vehicle and supposedly replaced the font and rear brake pads and rotors.
