I am no car mechanic so can not help you there but I don't trust handbrakes either so if pointing down hill I turn the wheels into the kerb and leave in reverse and if pointing up hill leave in 1st and point the wheels so it would run into the kerb might be an idea to tell her to do that until it is sorted.
I don't do rain or threat there of. dry rider only with no shame.
