( Left hand Side ) EBC replaces the rigid original disc with a Full Floater brake disc. The Full Floater, which is very complex and expensive to manufacture, offers decisive advantages when braking. The brake ring, which is sawn, drilled and ground from forged HPSR steel bars, can expand unhindered without deforming even during repeated full braking, e.g. when driving down mountain passes. The low carbon content of the HPSR steel used also proves its worth here, as it ensures very little structural change in the steel under the continuous thermal stress of heating up and cooling down the brake disc in tough road use. A Full Floater brake disc from EBC is always a significant gain in safety. - Brake ring milled from forged HPSR steel with low carbon content. - Brake ring milled from forged HPSR steel with low carbon content.
