put a wheel nut on and hammer it to get the studs out without damaging the thread.
on the rear theyre piss easy with drums.undo handbrake and remove drums then just smash them out
with disks you need to unbolt the caliper and disc then smash them out.
with the front you need to remove the hub. take wheel off, then caliper. then remove dust cap and split pin and undo the nut and remove the whole hub, then remove the 4 bolt and remove the disc from the hub then smash them out
