My Golf 1.6 FSi SE has just returned from a main dealer having had a replacement ABS Control Unit. I've driven it for the first time tonight and the brakes are almost non-existent. I almost have to touch the floor to make any difference to its speed, and the stopping distance is enormous, even at low speeds. I've had this car from new and am 100% confident that the brakes are far worse than when the car went in (they were fine before it went in).
Obviously I'm going to phone them in the morning, but if anyone could give me any pointers to enable me to talk sensibly with them I'd really appreciate it.
There are no warning lights on the dash, and my husband has had a quick look at the brake fluid and all appears ok. The only thing I've noticed is that when I pump the brake pedal I can hear what sounds like air (as though you're pumping up an airbed!?) - maybe it always did this but I just didn't notice though.

Any ideas anyone please?
Thanks
