Brake squeal with new stuff

Brake squeal with new stuff
Old pads and rotors were squealing, figured it was time to change them. Put new rotors and pads on the front, put hi temp silicone grease on the guide pins and clips. Luckily, I didn't see any abnormal wear patterns on the old pads.
They still squeal when I hit the brakes, even with new stuff and everything greased where necessary. What's up with this?
Also, I noticed it has calipers with 2 pistons instead of one. Is that stock? Only reason I ask is that my dad's full size truck ('93 Chevy Silverado K1500) only has one per caliper.

Ive had new ceramic or full metallic pads squeal in less I spray down the rotor with brake clean after installation to remove any greasy residue from the factory or even from installing them - Ive also had too lathe turn new rotors down just a touch to knock the factory glaze off, semi metallic pads don't seem to have that problem quite so much, also if your calipers are hanging up just a touch you might not be getting full pressure to the pads against the rotors

one thing i always do is put grease on the caliper piston where it contacts the back of the brake pad, and the same on the outside pad, grease up the caliper where it meets that pad too. basically anywhere where metal touches metal
