  • Q:

    I own a 1998 Lincoln Continental.. Recently replaced all Calipers, Rotors, Brake pads front and back.. It was pulling to the left while braking and even after replacing all of this.. it still pulls a little.. Tires are fine.. struts are fine.. What is left to replace? I was told it could be the Proportioning valve or a blockage in the brake lines themselves.. Any info would be appreciated.. Thanks.. Mary..

      sounds like your front brake hoses.

      Sorry, without the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. We would suggest that you take your vehicle to a certified mechanic for further diagnosis.

      i would try replacing the brake hoses-they sometimes get restricted internally which can cause the pads not to retract fully. usually you can see dicoloration on the rotors or experience premature pad wear. if the pads are dragging you may smell hot brakes or feel the wheels for overly high temperature after driving awhile
