Legendary review on Corvette ZR1 CCB to Iron conversion.
[Z06] RB XR70 brake pads test review

 

[Warren-RB]

Squeaking (street driving) and quick pad wear/rotor damage (for tracking) are two most common complaints for a CCB brakes, which lead most people to the belief in swapping (downgrade) to conventional iron brakes.

RB is a brake company dedicated to R&D on brakes for decades, and offers brake solution from the fundamental ground, on issues, improvement, or for any specific racing tasks. Since we offer both Iron (for 30+ years) and CCB (10+ years), so our opinion is deemed to be impartial.

We recently teamed up with Endless & Paid - The two most known brake pads suppliers for CCB rotors, their pads will be stocked in our Fullerton CA warehouse and certified in compliance with OE caliper fitment & any applicable standard (FMSI) based on our knowledge and in house capability including modifications as required.

We firmly believe, just like some members here, CCB is the way to go regardless it's for street or tracking and we look forward to working with you in meeting this seemingly impossible challenge.

Thank you for your participation and supports.

Here is a reply just posted.

Are these the correct, smaller size that doesn't create that ridge? $1200 for a full set all the way around is around half price of what I paid for OEM, which is nice. By "street and spirited driving", do you mean "not really for track"?

See pics below to illustrate how RB pads were designed when it was developed for ZR1 (same as 570S*) since 2014 to help you understand better why RB pads would not create those ridges.

• Real McLaren front rotor (purchased from eBay as is) .
• Real McLaren front pad (OE on right)

*Except milled spindle relief on backing plate corner.

Here's an update, finally. I ground down the pads today and will start driving the Mac regularly again for the next week or two and will report if the squeal is gone or not. The photos show how easy it is to just use your hand grinder to cut down the inner groove. I was very cautious to not cut too deeply, so the squealing might just go away for a few thousand miles, but it is a reasonable experiment. If it works, I'll cut all the way down to the backing next time.

Hello! Great post! I solved !

I have been having the same problem in my 570. Today I’m working with the dremel .

So I took a closer look at my rotors last week. That inner edge on the rotor is recessed from the silicon carbide surface of the main rotor. Does the pad develop a lip? The only other way I can see that it would touch that inner surface is if the surface of the rotor has worn away.

As the pad wears, it develops a high ridge which then eats into that area.

That's the pad area people are removing.

Dude! Those pads are DONE!! With that many heat/stress cracks and very little "pad life" remaining, I wouldn't be putting those back on MY car! 👀 Unless this is "just a test", then carry on... But I sure hope you have some new pads at the ready....

I have one set that's about 50% worn with no sign of a lip yet.

They look like that even when they're new.

Hmmm, not the ones on my car or the spares that I have on the shelf.... Is this a 570 thing?

I don't know. I was shocked the first time I saw them!

Here's a set of mine with one high speed track day on them, the cracking was present when I fitted them. Interestingly, that inner edge is lower than the rest of the pad, as if it was already chamfered, but I don't recall how they were before fitting. These came from the dealer and have the AP branding.

I think there are some new pads that are causing that wear. It would be nice if someone has a photo of a 100% new brake pad. but look at the video:

My pads can be seen here:

720s Carbon Ceramic disc hard and nominal numbers.

Does anyone know the disc hard and nominal numbers for CCB rotors for the 720s brakes and the 600lt brakes. I’m hearing it’s located on the hat of the rotors but I have steel on my car now.

More nice pics, similar to what I've done, but I wasn't quite as aggressive. However, when you say "solved", how many miles have you put on them without them squealing again?

I thought I had it solved, too, but after just a few days (less than a week) the squealing was back. Please report on the number of days/miles you've gone without the squealing coming back.

BTW, I've replaced my 570S with a 720S so can no longer experiment on my old car. I was fairly aggressive on my last pass but had the feeling the squealing was coming back already after a week or so, but I can no longer confirm...

Corrected "pad shape" and "compound" = No lube, no trim, no shim.
It's simply a proven no squeaking & durable pad from RB.

Very nice, when do the track versions come out? I just picked up a set of pagid RSC1's which need to be cutoff wheeled...
