  • Can I Install Fornt Disc Brakes on Star City

    Hi All,

    I Currently own Pulsar 150 DTSi & a New Star City in my native place. I would like to know if we can put Front Disc Brakes on Star City as the Drum brakes are really inadequate. Hence request you to please revert which MM disc barkes should i buy and what will be the rough cost involved to it.

    What will be the other thing which i need to keep in mind while doing the same?

      Anything is possible. However, you may or may not have a great deal of difficulty in doing a proper conversion, and here's why...
      First off, the Knuckles need replacing. For Drum brakes, you have knuckles that accommodate the installation of the Wheel Cylinder, Backing Plate and brake Hardware, whereas for Disc brakes, the knuckles only have the mounting through-holes for the Caliper. Also, the Wheel Cylinder will most likely be fed by a hard steel brake line which would have to be cut down and a flexible Brake Hose (Rubber or Braided-Steel is fine) installed on the end.
      Drum brake Wheel Cylinders take considerably less force to operate than Disc brake Calipers do (ie., Drums at 40psi to stop from 50kph in 5 sec. -vs- Discs at 90psi). To accommodate this on your vehicle, you have a Proportioning Valve which directs more or less pressure toward the front or rear of your vehicle, depending on the amount of pressure applied as well as how quickly you depress the brake pedal. On the Ford Contour/Mystique the rear brake lines utilize a Pressure Reducer which reduce brake pressure, so the Proportioning Valve in the Rear Drum and Rear Disc model vehicles are the same. Most vehicles are not like this, however, and if you replace all of the appropriate rear hardware without taking this valve into account, you will be replacing your rear pads and rotors quite often.

      Do you think its worth the effort?

        Proportioning Valve is only required if he is installing disc brake at both front and rear which has same cylinder to store the brake fluid.

        maher_mast : Yes. Its possible to fix a front disc brake set, but that should cost you about 10K.
        Setup includes new set of wheel hub to hold disc rotor, change your front fork setup to accomodate disc brake, change brake liners, fix a master cylinder to the handle bar.
        Don't go for second hand and please get entire setup done by an experienced mechanic.
        There are no short-cuts to any place worth going. So ride safe when you are treading uncharted roads.
