Sometimes that happens when I have the needle position wrong. If that isn't it, you might need to take it for a repair.

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.

Your manual should tell you what needles to purchase for your machine. Search for "Brother 523n needles" and see what comes up. Your local Brother dealer will have needles for your machine.

Your owner's manual should have information about the needle you need for your machine. (Part # Brother XE7064-001)

Your Brother dealer will have needles or you can search the internet for vendors that carry them.

Checking the needle
Sewing with a bent needle is extremely dangerous since the needle may break while the machine is being operated.
Before using the needle, place the flat side of the needle on a flat surface and check that the distance between the needle and the flat surface is even.

If the distance between the needle and the flat surface is not even, the needle is bent. Do not use a bent needle.

Replacing the needle
Replace the needle as described below. Use the screwdriver and a needle that has been determined to be straight according to the instructions in "Checking the needle" .

Raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up. (With models equipped with (needle position button), raise the needle by pressing once or twice.)

If you lost the screw down into the machine, you need to get it out or terrible damage will occur.

Needle breaks
1.the needle is damaged
2.the needle is not correctly inserted
3.wrong size needle for the fabric
4.the wrong foot is attached
5.the needle clamp screw is loose
6. Top tension is too tight
7. Machine could be out of time

I suggest contact brother.com or a dealer about the needles , cause
I've checked on the internet and on the brother site about the needles and couldn't find any information.

You can use Schmetz needles and the bobbins are Class A or Class 15. Both can be found where sewing notions are sold.

You choose the needle size according to the type of fabric you are sewing. This should be in the manual.

If you need a manual, you can download from the Brother website.

I had the same problem with my brother vx-1120 sewing machine. I set the needle to lowest position by using the hand crank. Then I loosened the knerled set screw that holds needle in place. Then I moved needle shaft till the eye of needle is just lower than the hook on the shuttle loop maker. It made my mechine work. There are instuctions for ajusting timing on machine but I think these mechines are built to not fix and throw out. Just because there where no ajustment marks at all on machine, any machanical machine will needed to be ajusted sometime.
