Floating brake discs are a specific group of brake discs that find their application in the most demanding conditions, on long descents and under high temperature loads. MAGURA and HOPE offer floating discs, which consist of an inner sleeve and an outer brake ring. The main advantage is that they prevent heat transfer from the brake and pads to the central part of the disc, which can cause the disc to twist. The large temperature differences in conventional discs between the outer brake ring and the inner spokes are better handled by floating discs, as the outer steel brake ring is free to expand and does not affect the inner pad, which in most cases is made of aluminium alloy.
