I don't know if that is the case with the yellows. In the link I posted. Performance Brake Pads Compared: Hawk HPS, Hawk HP Plus, EBC Yellowstuff | Car and Driver Blog The distances shortened as the pads got heat in them it but they stayed pretty consistent once warm after stop 6. They went from 100-0 with a mile in between stops. Most of Wilwoods graphs look similar for the Polymatrix race pads. I have never had a problem with their pads.

are the pads producing Tq at elevated heat ranges, yes. Calming "I never had a problem" is infuriating to me. because you are suggesting that the EBC's should be fine. but if you have these pads you will have an incredible Tq rise with heat. in all of my years as a brake guy i have never seen a 75% torq rise, little alone over 400*. when you are in a braking zone, trying to use 100% of your tires ( and not a percent more), checking your mirrors, monitoring other cars (my point is) with EBC you'll need to add another step and monitor your heat Torqe rise. while the people around you will not be doing that. that will cost you time. a 75% torque increase can cost you a set of tires, your a car, or your life. brake pads are a get what you pay for, don't cheap out.


i also hate it when auto journalists do brake tests. they couldn't do a brake test correctly to save their lives. i digress.

Don't be infuriated. I am just saying that Wilwood race pads have a similar torque increase with temps as the Yellows. Yes, as they get hot they bite more but this comes up as tire temps do. As you know this is how race pads are and for anyone that has had brake fade on stock pads will know, once you get a few laps, they get hot and stay hot. I don't know how accurate EBC's graph is but the magazine test looks pretty legit. Much more than many of the" I don't like pad X" posts that is seen in a lot with not much to back it up. Car magazines test cars for a living. Their tests seemed pretty legit. I have never run EBC and am not claiming they are good, great ect. I am just playing devils advocat as I have run Wilwoods with similar graphs and I know first hand that work they work. In the magazine article they got them pretty hot and didn't seem to have any trouble modulating them.

How We Tested: Each set of front and rear brake pads was paired with a set of new discs from -Mazda. Using dealer-supplied fluid, we bled the braking system [see “How  To,” August 2011] after every change. All the pads underwent a break-in process consisting of  15  0.5-g stops from 60 mph at approximately one-mile intervals. Our procedure included a five-stop -cycle consisting of one 0.5-g stop and four all-out -panic stops from 100 mph. The cycle was performed nine times to gauge the pads’ fade resistance. In addition to the usual speed and deceleration data, our Racelogic VBOX III logger recorded brake-pedal travel and force information. The 100-to-0-mph distance graph is the average of the four panic stops per cycle; the force and travel graphs show the 0.5-g stop at the beginning of each cycle. It’s important to note that upgrading a -vehicle’s brake pads doesn’t automatically result in shorter stopping distances because performance is -ultimately limited by available tire grip.

The rise of torque on the EBC yellow pads is interesting. I can attest that they have some bite. I had Yellows in conjunction with 1.6 rotors and calipers. My co-driver entered a braking zone at Nelson Ledges too hot and slammed on the brakes. He flat spotted a set of Yoke AD08's.

I changed to Cobalt XR3 and found the cold bite higher than the Yellows. They seem easy to drive.

I'd call BS on that EBC graph, regardless of its source.
But aside from that, Just as equally as worrying as the drastic torque fluctuation which that graph suggests is the notion of a "race" pad that doesn't tell you what it does above 900 degrees. That's like a dyno graph that only goes to 4500 rpm.

i tried green, red amd yellow over the years. I had enough power and fade resistance with the yellow on my lightened turbo na. But once i was on slicks with aero, they just wouldn't last that long. I went to Carbotechs and they are 100x better. Just a little noisy when cold. And they last almost the entire race season. 6 weekends and i change them out when they get 50% worn.
