Hi can anyone help me solve this problem, when ever it snows and i drive off from a cold start and i put my foot on the brake pedal , the pedal is locked solid and the brakes will not stop the car. i hear a grinding sound from the front brakes it sounds like metal grinding against metal then all of a sudden ill put my foot on the brake again and its working ok ive had the brakes checked by a local garage and they cant find anything wrong not even with the disc`s or pads have any scoring marks on them so where is the grinding noise coming from ?????????? :doh:
