Welcome from NJ. I'm not familiar with Brother machines in general and certainly not your specific model. That said, I see no reason why you can't, at least, piece your quilt top with that machine. Any machine can do that! Quilting the sandwich is a whole 'nother issue. Needle height should not be an issue but throat size could certainly be a challenge if it's small.
What type of problems have you had with the machine that it's not 'working right'? Give us some details and I'm sure someone will be along that will have some advice/solutions for you.
