How do you replace suzuki grand vitara front brakes?

just done it myself....the two grub screws holding the rotor(disc) on are hard to get off .I tried heating ,bashing with a impact hammer, but in the end what worked was penetrating oil ,in the right place.and allow to stand for at least a few hours and then i use a nail punch to put a small hole in the screw head and then hit it on an angle and the screw started to loosen........the rotor ,penetrating oil and let stand overnight and give a good wack the next morning.
