How do you stop her from squealing?

The disc brakes on your truck of course. There must be a jillion solutions for sale but which ones have you guys used that really worked? My discs are driving me crazy and I only want to do this once and get it right so HELP!

I usually hit the pads with the sanding flap disc on my angle grinder. If the rotors are really shiny and glazed over I'll hit them lightly with it too. No problems after that.

Apply a thin layer of silicone to the backside of the pads. Let it skin over, and re-install.

There are several things that can make disc brakes squeal on your truck.
1. The outer pads are not clinched tight to the caliper
fix: with the outer pad off of the caliper, with a pair of channel lock pliers, clinch the ear of the pad tighter so that it will require being pressed back onto the caliper with a pair of channel lock pliers
2. The inner pad is missing the anti-rattle clip or it is broken
fix: replace the clip
3. The rotors are glazed and need to be resurfaced
fix: resurface the rotors and put a non directional finish on them
4. The pads are glazed
fix: replace the brake pads, but not without resurfacing the rotors
5. The pads are setting up a harmonic against the rotor
fix: bevel the edge of the pads at a 45 degree angle, then clamp each pad in a vise and cut a groove 90 percent through the friction material in the middle of the pad, at an angle perpendicular to the rotor.
I have been doing the above since the inception of this type of disc brake in 1969, and have never had it to fail if done properly.
