Just replaced brake pads. Interesting. Take a look at the EBC brake pad on the piston side:



The pad backing plate appears to have gotten extremely hot, so hot that it changed color. I just jacked up the bike and the wheel turns freely; with the normal sound of the pads scraping on the rotor.

Is this a usual effect of the EBC pad material; to get that hot that the backing plate could change color? I only rode the bike around the neighborhood, didn't really get on the rear brake hard...
 
Been running those pads for yonks, mate, no probs.

ARE they actually getting hot? Maybe run around the block again and try to sizzle your fingertip on one?

If you are hardly using the brake, they can only get hot if the pads are dragging. That can only happen if the pistons are sticking, the caliper's not sliding freely, or you didn't get ém in right???

Probably, if only one's hot, the caliper's not free to slide.

End of guesses!!
 
I'll check the caliper pins and re-grease them tonight. The rear rotor is definitely hotter than the rotors on the front; which are still using the OEM pads.

As the general consensus is that EBC pads give better braking it would follow that the level of friction is greater than with OEM pads - thus greater heat transfer. Just my guess.

My other guess was that as the fixed pad is basically attached to the calliper it has a bloody huge heat sink. The moving pad sit's in more of an air pocket. So retains heat in the back plate. But I'm guessing too.

Take it around the block and just use the front brake. If it is getting hot, you have the caliper dragging the outer pad on the rotor.

I actually did that midday today. The rear disk stayed cool. I guess it was just me applying too much rear brake initially; after I installed them.

Did check the temp of the rear rotor after I used them once; later on. With the new EBC pads; that rear rotor sure heats up A LOT more than with using the OEM pads....
