This drum was developed in the same principle as the old Wellworthy drum with an aluminium outer case and cast iron liner but this drums employs a unique mechanical locking system designed to ensure that during the repeated expansion and contraction of materials under the most extreme working conditions it is impossible for the liner to move axially or circumferentially. Racemettle brake drums are built to the highest standards of quality and design to match or exceed the appearance and performance of the original aluminium brake drums. Our drum comprises a cast iron insert that is placed at temperature into a high integrity boxless sand casting system and is then encapsulated in an aluminium alloy chosen to give low differential expansion and high elasticity. Design of the drum is optimised to increase aluminium flow avoiding entrapment of air. Material analysis performed before each melt ensures consistency to the manufacturing process maintaining the high level of quality and accuracy to the casting.


The drum was developed to provide increased breaking efficiency by reducing brake fade. Aluminium having good thermal properties to dissipate the heat to the atmosphere that is generated under braking  also brings the benefit of weight saving, a typical 10” drum being over 0.5 kg lighter than its cast iron equivalent.
