Hello everyone, I hope you’re all well? This is my first post here but I’ve been reading for a while. I’ve got a 2011, 140bhp 4x4 diesel yeti. When I first got it I drive back from York to sheffield and the brakes were awesome. I went out for a drive in the peaks that evening and I pulled over in a gravelly lay-by and then the abs cut in and the car stopped the pedal wend virtually down to the floor. For the 8 mile drive home the brakes were rubbish with hardly any pedal! The next day they had come back mostly but not as good as the day before. A couple of weeks later I had the cam belt done and I asked the garage to check the brakes and they said they were fine. Over the last few months they have got worse and worse to the point now where I have to pump to get them to work! I noticed in the snow that after setting off if the traction control kicks in the brakes pedal gets instantly worse! There’s no fluid loss. A friend put it on a computer yesterday and run the brake system but there are no faults at all. He says it’s more than likely the abs module but I thought before I shelled out for one of those I’d check here to see if anyone had come across this and had any ideas? Thank you for any help
