    Default Brake Caliper Jams Disc At a Specific Point.

    My bike has a front disc setup, facing issue of wheel jamming.

    In details, the brake caliper is jamming disc at a specific point only, like the wheel is rotating freely and stuck at one point. I have tried another disc and this second disc is also jamming at the same point, strange? I mean I noticed it by observing tube-nosel position.

    For both disc when tube-nosel reach this point (see image below), wheel is jamming. Wheel jamming gets even worst in longer run may be pads get heated. Before replacing the disc, we did the bleeding to remove any air. In all the process, the brakes is working fine like it stops the bike, grips is ok but that wheel jamming at one point I am not able to figure out, may be drum is out at one point.

    What are the radial runout readings for the rotor, wheel and the axle? One of them might be over limits. Or bad bearings.

    Not sure about the exact specifications. But it is GTO 125 original fittings.

    Two possibilities for this.

    1 - disc is warped
    2 - disc mount hub is warped or there is debris or foreign material trapped between disc and hub
    3 - caliper slide pins are worn and sloppy
