You would need to qualify to sponsor your mother and include your brother as a dependent in the application. It's hard to comment on how achievable this is since it's dependent on your brother's condition, if Canada believes he may be a burden to health care / social care systems and other factors.
You will need to wait until the parent sponsorship program reopens and will need to make sure you have enough income to cover your own family as well as your mother and brother.
