This is what I was referring to when I said in the above that, I prefer brake pads with a Coefficient of Friction(CoF) of "FF". When in fact some folks who dislike newly installed pads, whether installed by one's self or a shop that you may just be getting Cof of "GG" and not know it. I DON'T LIKE'EM!
CoF "GG" pads may in fact fade less under extreme conditions(e.g., WearEver GOLD) but, I don't like'em. Give me "FF" any day!
I installed WearEver GOLD ceramic pads on a Lexus w/o knowing that they were "GG"(instead of "FF") and I hated them. Keep in mind that not all applications of brake pads/mfg's are FF or GG, you have to look. My W/E Golds were, others may not be.
Same with any brand of "FF" or "GG" that I've used. However, I can't answer for every brand and/or CoF. This is just my experience and others do like "GG" more than me. If you want your car's brakes to feel like OE, use "FF" or whatever they came with.
Where do you find that spec? Now I really want to know exactly what I have and what to look for.
EDIT - I guess I found my own answer
here:
"Notes: These edge codes are located on the edge of the friction material of every brake pad by government regulation, along with some other codes. The first letter is a grading of the C.F. at 250 F and the second letter is a grading of the material at 600 F. Each letter grade can actually have quite a range of C.F. But a difference in the letter grade from medium to hot temperature could be an indicator of fade. The letters can be in any order. Therefore FE pads fade when hot, and EF pads would not grab when cold.. Also, you should know that Steel on Steel has a C.F. of 0.25!! So EE pads have only marginally more torque than no pads at all! Therefore FF pads are usually considered the minimum for a high-performance pad."
