I have a left-hand drive 2003 Opel Omega which has done 50,000 miles. I have owned the car from new and it has been dealer maintained. In March 2010, upon braking, my car was pulling to the left. I had the brakes checked, as it was felt that the disc brakes might have a sticky caliper. This was not the case. The brakes were fully checked and tested. I also fitted four new Bridgestone tyres and had them aligned, balanced and checked. I checked and changed the front wishbone arms and front drop link pins. All seemed OK. Last week my rear spring went, which I replaced, and upon closer inspection both new front tyres were almost bald. I had to replace the two front tyres for two new Bridgestones. The tyres were aligned and balanced. I also had a camber test conducted on the car. My car is still pulling when I brake. What can be wrong?
