Operators are being warned about seriously defective aftermarket brake drums that may be fitted to Scania P400 lorries within their fleet.
We are aware of 2 cases where aftermarket drums, which were not manufactured or supplied by Scania, have failed on P400 lorries.
No front braking
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 have been unable to identify the manufacturer but have released an image of one of the failed drums and are asking operators to let them know (on 0117 9543425 or email@example.com) if they have similar drums fitted to their lorries and their supplier.
