EBC Brake Pads discoloration

Replace my brake pads before a trackday because there was a chip on the EBC EFPA. I wanted the same ones unfortunately no one has them locally. I used the EBC HH that was available at cycle gear.

During sessions. Towards the 2nd to last sessions they dont seem to have the stopping power as I trail brake.

Pulled them when I got home. They turned pink.

Are they done?

Thanks

Re: EBC Brake Pads discoloration

you didn't prep the rotors and you didn't bed the new pads in. they got hot. go get a red 3m scotch brite pad or 120 grit sand paper, or buy a rotor hone, sand the rotors to remove all the old pad material. it doesn't take a lot of scrubbing. lay a piece of 120 sandpaper on a good flat surface. rub the pads on it in a figure 8 until you remove that burned look. go ride the bike and bring it to several moderate slow downs from about 50 mph to about 10 mph. allowing the pad to cool down enough between. after a few of these you should feel the pads increase in grip. after that they should be ready to rock and roll.
now depending how fast you are, they may not work too well after they get some heat from track riding. if you're fast as **** you'll have to move up to race pads. these pads are only for street and medium pace track day riders that are mostly coasting into the corners.

I prefer Ferodo brand of pads myself. I'm not super fast but I do weigh close to 200 so my brakes get a decent workout. their ST pads are like these EBC pads but they seem to be able to control heat and never fade.

I did prep the rotors but I guess I didn't bed in the new pads properly. I was trying to bed in in the pits but only 20 down. I trail brake into the corners.

Thanks for the help and I'll look into ferodo pads.

maybe you didnt get the all of the old pad materials off. when changing compounds it's important. bedding them in should happen within a few stops regardless how you did it. when I changed them at work I would just drive the bike around the parking lot and stop the bike a few times hard. it helps we had a big hill. that was plenty of bedding in 99.99% of the time. then i'd ride it on the road just to make sure it was good to go. we sold ebc pads.

well now you know why Cycle Gear is completely useless. HH is the stock compound. Total garbage for spirited riding.
Im suprised your trackday didnt have a vendor present since R6 pads are the modern Chevy 350 of Japanese motorcycles...lol. Also how worn were the previous pads? I cant imagine they were worn to the point you couldnt use them 1 more day.

I pulled out the pads to clean my calipers before trackday. This is how one side looked.

Re: EBC Brake Pads discoloration

definitely enough meat on there to last the day. I might send an email to EBC to find out why the material broke away. Could be a manufacturing or batch defect and they are usually pretty good with tech issues.
Also you can bevel/file those damaged areas and keep as spares in the future.

How dirty were the calipers?? From the looks of the backing plates... pretty filthy.

Yup. Pretty dirty. I normally clean them every year before my 1st trackday of the year. I probably should clean more often.
