Warning about seriously defective aftermarket lorry brake drums

Date: Thursday 24 September 2020

The DVSA is warning operators about seriously defective aftermarket brake drums that may be fitted to Scania P400 lorries within their fleet.

The DVSA is aware of 2 cases where aftermarket drums, which were not manufactured or supplied by Scania, have failed on P400 lorries. Both lorries were left without front braking and were fully laden.

The drums failed in the same way when the braking surface fractured and separated from the mounting ring. It is believed that this was not due to normal wear and tear.

The DVSA has been unable to identify the manufacturer but an image of one of the failed drums is shown above.

They are asking operators to let them know if they have similar drums fitted to their lorries and their supplier by calling 0117 9543425 or emailing

Vehicle safety defects can also be reported at DVSA's online vehicle recalls and faults service.
