SIBS incorporates improved heat management that results in lower operating temperatures.

It does this in two ways: firstly, maximum thermal mass is utilized; and secondly, the surface area for rejecting heat is matched to the heat generation rate. Maximizing the thermal mass differs from simply increasing mass, as is often employed within brakes. SIBS is comparable in weight to conventional brakes.

SIBS cooling fluid enables heat to be transferred from the disc to the housing, and in turn to the axle mounting. The inclusion of the caliper and axle mass maximizes thermal mass and reduces the resulting temperature more effectively than conventional brakes, ensuring that the temperature is not excessive for either the brake fluid or bearings.
 

The graph below shows the temperatures that result within comparative testing for a conventional dry disc brake and for SIBS. As seen by this illustration, SIBS brakes only heat up to 200°C, while the corresponding temperature for conventional dry brakes is twice this figure. The lower temperature for SIBS is a result of the improved heat management.

Where heat generation rates are large due to high speeds, large masses or continual operation, additional surface area is incorporated to aid heat rejection. This can either be on the brake itself or can be remotely increased by a radiator connected by coolant.  SIBS can incorporate coolant flowing within the housings to transfer heat away from the brake.  Reducing the operating temperature of SIBS dramatically improves its durability. High temperature operation increases wear and can also lead to premature failure of the disc due to thermal stress.

As temperature increases, brake materials soften and the force generation ability reduces, resulting in fade. Lowering the operating temperature of the brake components ensures that heat related brake fade is not observed.  SIBS eliminates heat related problems, delivering dependable braking.
