    thank you so much for the information!
    i had been wondering if this was the case,
    and have decided to use different thread instead.
    i'm going to use size 69 bonded polyester thread with a size 18 needle.

SOURCE: industrial sewing machine top thread breaking

The brother DB 2 series of machines do not use a needle with a flat side. the needle system is DBX1 and are available from size 10 to size 20.
Try using the right needle for the machine and the right size for the thread you are using. this should make it better

SOURCE: needle clamp won't attach to needle bar

There is a set screw above the needle pin screw which tightens with an allen wrench--try that.

If you're having the same problem we did, the attachment is installed too high on the bar. Move it down as far as possible and see if that solves the problem. If it doesn't, check to see whether the machine is belt-driven; did the belt break or slip off?

What size needle do I need for a brother db2 755 mk3?

Contact your local Brother dealer. They carry the needles you need for your machine. The needles should all be the same length for your machine. If you continue to have issues with your machine, be sure that you ALWAYS RAISE the presser foot when threading the top thread. If there are still more problems, you may have knocked the machine out of time when it broke the needle.

How to replace the needle bar

There are only a few times when you need to change the needle on a sewing machine. One time is when the needle gets dull and it becomes difficult for the needle to pierce the material. Another time would be when, for whatever reason, the needle breaks. A third time would be when you change from sewing one weight of material to another. Whatever the reasons, changing a sewing machine needle takes only a few minutes to do.

these are the steps....

  • Move the power foot control away to prevent accidently pressing it while changing the needle. Turn the hand wheel that is located on the upper right side of the sewing machine. Watch the needle while you are turning the wheel and stop when the needle is as high as it can go. If the thread is still inserted into the needle, pull it out.

    Find the small clamp that holds the needle in place. It is located on the side of the needle bar. Grasp the clamp and turn it to loosen the needle. You don't want to remove the clamp entirely, just loosen it enough for the needle to be removed.

  • 3

    Remove the needle from the needle bar. If you are having difficulty maneuvering to get the needle out, open the needle plate. Be careful when removing a needle, especially if it is broken, to avoid sticking yourself. Set the needle aside, if you are switching out needles to use one for different weight material; otherwise, throw the old needle away.

    Select the correct size needle. The different sizes are written on the colored end of the needle that fits into the sewing machine. Turn the needle so that the flat side is facing away from you. Slide it into the needle bar until it reaches as far as it can.

  • 5

    Hold the needle in place with one hand and grasp the needle clamp with the other hand. Tighten the needle clamp. Do not turn it too hard to avoid breaking it or stripping the threads on the clamp.

    Clean any thread or fuss that is caught in the needle plate of bobbin case. Turn the hand wheel several times to make sure the needle is securely in place. Thread the needle and continue sewing.

    The neddle is hitting the medal instead of going in how do I adjust this problem on a brother es 2000 machine

    Check to see if the needle is bent. If that is not the case you need to adjust the needle position on the needle bar. This may be something that you want to have a technician do, so you don't change the timing on the machine.

    Skip stitch

    The three most obvious causes (other than that of the machine possibly being slightly out of time) are:

    1) Too small of a needle size - increase the size.

    2) A needle that has a flaw / defect - change the needle.

    3) Needle not inserted correctly, either not pushed all the way up into the needle bar, or not installed facing the correct place. On this machine, the small "scarf" in the needle (an indent just above the eye) shouldface the right side of the machine.
