  If your Brother Sewing Machine needle breaks, make sure it is correctly installed, and the needle clamp screw is tightened with the oval screwdriver. Replace the needle if it's bent or blunt. Ensure the upper thread is correctly threaded, and you're using the right combination of fabric, thread, and needle. Use the correct presser foot for the stitch you're sewing. Loosen the upper thread tension, and gently guide the fabric instead of pulling it. Properly fit the spool and use a bobbin designed for the machine. If the needle plate area or bobbin case is scratched, contact your retailer or authorized service center to replace these parts.
