I found quite a good article on brake judder and other issues with brakes. Enjoy:

Also on bed-in:

Good reads.

 

I would disregard this paper, unless you are running 'powerbrake' brake pads.


Follow the instructions of the manufacture and you will be good.


Not all brake pads require a "bed-in". Cobalts Frictions line of new pads XR series do not require any bed-in.

 

is the side of the first article cut off for anyone else?

its cut enough to where i can't guess at some of the content

EDIT: went back and re-read it, i overthought it, its barely cut off, i guess my brain isn't working so well this late

 

These papers and their conclusions are very similar to the ones on the Stoptech website. And they are also consistent with the instructions given by most manufacturers of performance brake pads. So the instructions of your brake pad manufacturer are quite likely to be the same as the instructions given by both of these manufacturers.

That's close, but not entirely true.

There are a couple of reasons for bedding pads. One objective is to get the pads to outgas. With most pads, if you don't bed your pads before you go out on the track, most pads will fade (BIG TIME) during your first and maybe second session on the track, while the resins in the compound outgas when heated. After that, the outgassing is complete, and hopefully, the pads won't fade for the remaining life of the pad. The XR pads from Cobalt don't need this outgassing process because their compounds don't contain resin, and it is this specific bedding purpose that is addressed where their website says:

However, another objective of bedding pads is to leave a uniform layer of brake pad material on the surface of the rotors. Without a proper bedding process, brake pad material can accumulate in an uneven layer (some spots and not others) and this can result in brake shudder. Most performance brake pad manufacturers recommend bedding pads off the track, with a cooldown after the bedding procedure, in order to leave this uniform layer of material on the rotors. According to the conversation I just had with their staff, Cobalt recommends an off-track bedding procedure with the XR pads if you are using rotors on which any other type of brake pad has been used, so that the existing layer of material from other brake pads can be worn off by the XR pads and replaced by XR material. They say that no bedding procedure is needed with XR pads if you are using brand new or newly turned rotors, or rotors previously used with their XR pads, because the material left by the XR pads will be sufficiently uniform on the rotors.
