Den skal så lige udfordres
: her et citat fra Wikipedia: "The "gaseous boundary layer" is an hot rod mechanics explanation for failing self servo effect of drum brakes because it felt like a brick under the brake pedal when it occurred. To counter this effect, brake shoes were drilled and slotted to vent gas. In spite of that, drum brakes were abandoned for their self servo effect. Disks do not have that because application force is applied at right angles to the resulting braking force. There is no interaction.
Adherents of gas emission have carried that belief to motorcycles, bicycles and "sports" cars, while all other disk brake users from the same automotive companies have no holes through the faces of their discs, although internal radial air passages are used. Vents to release gas have not been found on railway, aircraft and passenger car brakes because there is no gas to vent. Meanwhile heavy trucks still use drum brakes because they offer more heat dissipation than disks that would fit in the same space. Railways have never used internal expanding drum brakes because they cause skidding, causing expensive flat spots on steel wheels."
