Well, I just think women from your country are gorgeous. That's why I was saying, pics....Sometimes I like to be shallow. It's normal for someone to like to look at pictures of gorgeous women. Sorry I gave no advice on your brakes. Seems it had already been resolved.

See. I was right about you. Well, no matter where we are born. We really are all the same. Human beings have been here for so long. Everyone shares similar traits, DNA and so on. We are all the same. Nice pic by the way and let us know what happens when you change out that brake fluid.

Brake fade after 20 minutes of continuous hard braking is sort of expected, isn't it?

That generates a LOT of heat.... once you start cooking the brake fluid, the response is not going to be very consistent.

I presume you are using the highest quality racing grade brake fluid you can find?

All of the heat is being generated, from stopping the bike. 200 kg, + you, from some speed, is quite a few KiloWatts of energy.

I'm pretty sure the issue is the heating of the brake fluid. That comes from the pads, through the pistons, to the caliper, and from there into the fluid itself. Better quality fluid should slow the rate of degradation, and let your brakes work as designed, longer.

You may be able to purchase pads that have more grip, so you use them less for each stoppie. If there were an insulator between the pistons and the pads, that would slow the heat transfer significantly.

The whole reason sport bikes have two disc brake systems on the front wheel is to shed more heat, due to the greater surface area. A single disc system can be just as powerful.... but it will overheat more quickly.

I would think any HH rated pads would provide more friction. I don't have the need to change pads on my bike yet, as I mainly commute on mine and don't race or stunt on the thing.

EBC, SBS, Galfer, Ferodo are all manufacturers who have been selling motorcycle brake pads for decades... any of these should work.

If you have some generic pads in your bike, they may have glazed over and lost friction as a result-- if the surface is shiny like a pottery glaze, they would not stop very well.

You could try taking the pads out, and scuffing them with fine sandpaper. All you have to do is knock off the shiny surface.

EBC HH pads are fine for street riding, but, in my experience, if you abuse them them they glaze and warp.

Don't think those pads will be able to take the 20 min stoppies unless it's the EBC extreme pro compound.

Some brakes like the galfer 1375's have a ceramic coating that helps dissipate heat well and most (if not all) race pads are made to operate at those high temperatures without fade, however it is not advisable to use those race specific compounds on the street.
