Front Brake rotor
K2-K6:
interesting outcome and good comparison.
I find, on all type of material for both pads and disc, that using brake cleaner on the friction surfaces takes longer than you'd think to dissipate. They really don't show their best until properly burnt in and up to full potential.
Certainly worthy of more time in running them, also sticking as much heat into it as practically possible to make sure they "clean" up before a full judgment.

On my 500 I used Meths on my front Discs applied with 1000 grit, so far a complete waste of my time it's made no difference.👎
Mikep328:
Being naturally curious, today I removed the Versah pads, cleaned the rotor with brake cleaner, installed organic (DSS) pads and went out did the same break-in. I don't know if this would apply to any organic pad/this rotor or not but the result was that a good brake with the Versah pads became an unsatisfactory brake with the organic pads - less initial bite and a lot more pressure required to get less stopping power/much greater stopping distance. Totally unacceptable.
Tomorrow I'm going to do the drill again, this time with new Brembo ceramic pads. If they aren't at least as good as the Versah pads, I'll reinstall the Versahs and bed them in (again).

Definitely interesting to hear your experience with straight comparison of materials Mike.
From trying many brake pads in different vehicles and use profiles over the years, I'd agree with your observations of these two so far. Quite different in character aren't they!
Ceramic pads, I feel are generally consistent often without a potent initial bite, linear build up of braking effect with increasing line pressure, may need more absolute mastercylinder pressure to capitalise on the far reaches of friction.
Emphasise (think I noted before) that it takes longer than many think to clear disc cleaning effect and develop fully the pad's ultimate potential. Much heating often needed through harsh applications :)
Mikep328:
We plan on a ride tomorrow - maybe I'll leave the DSS organic pads in place and put more heat into them, see how they feel when I get back home.
FWIW the Vesrah pads are, per the label also "organic." Vesrah describes them as: "Vesrah Organic - Japanese brake pads made from metal alloys, a blend of carbon-kevlar, and many other components."
There are dramatically more visible "metal particles" in the Versah organic pad as opposed to the DSS organic pad.
