Thread is getting caught in hook, breaking

[jbnt9999]

My bottom thread keeps breaking and it’s getting caught in hook. I have a video but it won’t let me attach. 

Here is a picture.

I can't tell for sure, but it looks like your thread is getting caught in the hook's race.  If your hook is in good condition, I don't think that should be happening.  It would seem there is too much clearance, and the hook needs to be replaced.  To test, pull and push on the center post.  If there's any movement, the hook is bad and should be replaced.  If you need to replace the hook, and you want a larger bobbin, it might be a good time to upgrade with an M bobbin conversion.  Jim

HI, I'm having the same problem intermittently, the picture above looks like what I'm getting.  Also my bobbin thread seems to be shredding a times.  So I pulled and pushed on the center post and it didn't move but I heard a metallic rattling noise and it seems to jiggle just a little but hardly any.  How much movement are we talking about here?  

 

TIA,

The metallic rattling you heard is probably the bobbin basket hitting the finger that controls it's travel.  It's hard to fiddle with the hook without rotating it sightly, and that might be what you're feeling.  There shouldn't be any play in the hook.  It should only rotate and not move any other way.  Jim

It's bit difficult to spot the issue. Here is something I found online. I think it will be useful to identify the issues. https://support.brother.com/g/b/faqend.aspx?c=us&lang=en&prod=hf_600_2eus&faqid=faqh00000318_000#:~:text=Make sure the spool of,for the size of spool.&text=The bobbin thread is not,correctly wound%2C rewind the bobbin.
