Question about Sewing Machines
Breaking thread usually results from mis-threading or tension too tight. Install a brand new needle. Try a different brand of thread (AVOID old or bargain bin threads!). Set the tension at the midway point between high & low number.
Does it sew fine for a couple of inches and then pop? Watch the thread, does it get tight between the spool and needle before it breaks? If so, the thread is hanging up somewhere--is there a nick or slot on the thread spool itself that is catching the thread?
Remove the thread completely and re-thread from the beginning. When threading, ALWAYS RAISE the presser foot so the thread will seat in the tension disk. Verify that the thread path is correct and that nothing has been threaded out or order or missed. Check that the thread is not snagging on a burr or nick.
Confirm that the correct needle is being used for the thread and fabric, ie the thread is too thick for the needle's eye. Usually, the symptom is shredded or frayed thread at the needle eye.
All About Needles
There could also be a burr snagging the thread at the needle plate or around the bobbin area. Wrap a finger with fine fabric (old hosier, chiffon, silk) and run your finger around the needle plate and bobbin area. If it snags, you know where to look. If it's a small burr, it can be smoothed (gently!) with a fine emery board or sand paper. If it is a large burr, it should be taken to a technician or a replacement part installed.

Check your threading path with your manual. If, you look up your manual online at brother.com it can be made larger and you may spot your mistake easier.

Well, Madalyn, when was the last time you oiled the machine. Go to http://fixsewingmachine.com for tips on that and on tension, timing, cleaning the shuttle race, etc. , but now, let's talk about this particular problem you are having: it sounds to me like you could use a new needle of the correct size for the type of fabric/weight of fabric you are sewing. Also, sometimes sewists think they have that needle all the way up in the needle bar shaft, but...oops! no, it's not, and sometimes they also forget that the flat side goes toward the back of the needle bar. Also, sometimes sewists (not necessarily YOU, Madalyn, but SOME sewists, forget to turn the handwheel toward themselves and keep that presser foot in the UP position when they thread the machine. What happens? Yep! The tension discs do not open all the way up for thread to locate the tension discs and creates a problem. Make sure you clean the shuttle, the feed dogs. No big deal. Relax, get the little brush. Much success!
