That sounds like a vacuum/servo assistance problem. That isn't a rubbing sound and bleeding the brakes won't cure it. I have read somewhere of a brake booster problem on these and the Prius which is sadly quite expensive.
Good luck sorting it

It will have an impact on braking performance as it will be lacking in servo assistance. I would get it leak tested first to see how bad it is.
