More Info:due to Bluestuff having excellent cold friction and being very controllable, this compound has quickly become the brake pad of choice for performance road car drivers in USA and Asia markets where R90 homologation does not apply. More recently, EBC is pleased to announce that Bluestuff has passed extensive road-focused testing and gained R90 approval on most E.U. fitments, making it unique in being the first truly track-focused pad which is also perfectly legal for use on the public roads across Europe. There is no requirement for E.U. customers to inform their insurance company following the fitment of R90-approved pads. When planning a track day, even bedding in of the Bluestuff and Yellowstuff grades is essential that you bed your pads incorrectly. As we tweak compounds to further gain performance this advice changes, our latest advice on bedding in these two Hybrid grades for track use is here. Bed-In Procedure: EBC Bluestuff are heat scorched which helps bedding times but you still need to take care especially on the highway and when using on part worn rotors. Use the brakes gently for 200 miles, gradually increasing demand on the brakes in a SAFE ROAD ENVIRONMENT until you feel totally confident and can evaluate their stopping distances in all traffic conditions. Remember, it’s down to you and your bedding-in process. If you do feel brake fade a couple of times and even smell the brakes, this is totally normal and once achieved and the brakes are allowed to cool, they will have improved a lot. Perform the Street Pre Bed Fade 1 routine as above (either on the road or at the track if installed there ) followed by Fade 2 at the race track. The latest Bluestuff DM3362 and Low Mu versions should only take Fade 2 and a 15 minute cooling time to be ready to race. Fade 3 should not be necessary unless poor disc condition has prevented proper seating but if you have time DO perform Fade 3. See more EBC Brakes
