Gray milky oil.
I just changed my rotors and brakes (front) on a 1997 f-150 4x4 4.6. L Now there is a gray milky oil coming from somewhere and it's on my caliper and spaltered in my wheel well. Any ideas? Does front dif oil run to the boots on the front drive axle?
thanks

when you did the brakes you compressed the piston in the caliper back that forces the brake fluid back into the reservoir cap on or off the fluid would leak out and onto anything and everything underneath so the gray fluid could be brake fluid it has a very unique smell and texture to it
it could also be from a rubber hose to your caliper if you let it swing back to the ground when you unbolted it from the bracket so I would check for a spongy/non existent brake pedal...
that be the case you are looking at about 2 hours worth of work to replace that hose and bleed the brakes
could also be grease from axle boots... but grease is a lot thicker and you'd know it
my recommendation is to grab some brake cleaner (2-3 cans) and clean off everything and drive it for a bit and then go back and check wherever the fluid is wet there is your leak or if there is no leak then it was just residual fluid from your recent brake job... always check the fluid level in the reservoir when your done

Milky oil sound like water contaimination, start at the last place first, when you pushed the pistons back into the caliper, you disturbed all the dirt and any moisture build-up you had in your brake system, your truck probably hasn't replaced the brake fluid or calipers in a long time. You also have another thread about your a/c system, 10 of us might give you 10 different options, invest in a good maint manual and save yourself some headaches. Alot of maint/repair manuals are available on-line. Good luck and enjoy the wrench turning.
