-mistake number one mate.
* you should have had a bedding in procedure *each pad compound has thier own....my Pagids were x7 90-50mph (mid-peddle breaks) leaving a while for discs to cool between pumps of pedal,then x3 120-50mph (harder peddle breaks,with a few recovery pumps) ..bedded in a treat,and no squeeling issues to start.

Hi mate,my name is Andy.
I used to run EBC redstuff on my VIII,and found them not to be the greatest pad compound.
The yellow stuff pads are supposed to be better, but still IMO -not a good pad.
On my lastest brake change/set-up...
I took off my EBC crossdrilled,grooved and vented discs,and OEM brake lines,and pads.
they were re-placed with DBA 5000 2 piece floating discs that are slotted,and DBA 4000 1 piece slotted discs at rear,with HEL Ti braided brake lines,and Pagid RS 4-2 (blue's)brake pads rated to 600 degrees celsius operating temperature,and were not supposed to be "too harsh" on the discs.
I used Millars racing brake fluid too.
The difference is truly night and day,and the only problem I have is the brakes squeeeeel like a bi@tch now,but if I heat-cycle the brakes the squeel seems to go/dampen,and only really happen's when it comes to stand still.
I have been advised to re-fit pads using some ceratec paste between pad and shimm, you can also buy anti-squeel brake shimms , as the OEM brembo caliper on the Evo's are known for squeel.
Hope this is of some help mate!
drop me a pm if I can be of any assistance
Kind Regards,
A.
