Wait until the discs/pads need replacing, buy a couple of hub bolts, take the hubs off and fit new shields & brakes as a job lot

I would retain the shields as they keep harmful brake dust away from the dampers and bushings.
You will need a big ol' breaker bar to achieve the 180 degree final torque though.
