I just think semi-met shoes and pads are a poor choice. They are hard on the rotors/drums. They are a major cause of the evil red/orange brake dust. Most of the brake dust is rotor material!
Saying Ceramic is like saying blue shoes (no pun intended). They come in many shapes and sizes.
I recommend the following from personal experience.
As far as pads the Summit ceramic and the Powerstop Z-16 pads have a crisp initial bite and have a very linear coefficient of friction throughout the whole temp range.
As you go up the Powerstop ladder of pads the Z-23 have a softer hit and grab a little harder when hot.
The Z-26 pads take this a little further and the Z-36 I have on Frank have a VERY soft initial bite (so you don't lock up on ice if you look at the brake pedal
) but the hotter they get the harder they pull! Just what the doctor ordered for heavy towing. They have exceptional brake feel in my opinion.
Regardless of the pad/shoe you choose bed them in (break in) the way the manufacturer recommends. It really does matter. The brake frictions we have today are very different from the ones from just a few years ago.
