Bluestuff NDX is an intermediate grade trackday and race pad making it the material of choice for many club level racers and serious trackday enthusiasts. However, 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 are pleased to announce that Bluestuff has passed extensive road focused testing and gained R90 approval on some 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 fitment of R90 approved pads.
For customers with experience of EBC’s widely acclaimed Yellowstuff material, Bluestuff boasts a similar friction profile but with a usefully higher friction coefficient across the now larger working range, feeling much like you’d imagine Yellowstuff to feel after a double hit of espresso. Bluestuff has a high friction coefficient without feeling grabby, taking things up a notch from EBC’s Yellowstuff material by bringing superb pedal modulation to a track pad with even greater fade resistance.
The curve shows that friction builds quickly during bedding in even after 2-3 stops but in a real world TRACK USE where rotors may not be perfect and calipers not serviced weekly (like our lab dyno ones) the bedding in process with Blue may exhibit 20-25mm contact bands in the centre of the discs after 4-5 laps and on some standard street calipers some vibration.
This is simply the pad telling you “ I cannot hold onto the disc at these torques until I am fully bedded in”. If vibration happens you should continue driving whilst BRAKING EARLIER TO BE SAFE until the contact band widens to almost entire disc/rotor sweep at which point the vibration will stop. In street use the torques will not normally be enough to generate vibration during bed in but drive safely for 200 miles gentle brake use to bed in your new brakes and test them to performance in a safe and quiet road environment until you have total confidence that they are bedded. Hitting the brakes too hard, too soon can not only shorten pad life it may cause loss of brakes and an accident. Bed brakes in progressively.
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.
There are several ways of surface scorching pads and EBC has chosen an infra red lamp tunnel for surface preparation of its pad ranges. The furnace is now scorching all pads for resale including the Bluestuff NDX range.
Pre-bedding burns off a lot of the volatile organics in the brake pad surface by passing the pads under an apparatus similar to a toaster after manufacture for a few seconds; this chars the surface and the paint around the pad surface but the result is a major reduction in bed in time which all drivers will appreciate.
