Speaking as some one that has had LM grease turn to oil in wheel bearings it's better to stay with wheel bearing grease, this grease is formulated specifically to lubricate automotive wheel bearings, which turn at high speed.
Wheel bearing grease will tolerate the heat created by your brakes and transmitted to your wheel bearings.
Use LM grease for all the other greasing jobs u have although wheel bearing grease can be used for general purpose lubrication ball joints, prop shaft etc.
