Automatic slack adjusters have been a mandatory fitment on most trucks, trailers and passenger-carrying vehicles since April 1995: specifically, on category N2 & N3 LGVs, O3 & O4 trailers and M2 & M3 PCVs. So the few manual slack adjusters out there will be fitted to vehicles more than a quarter of a century old - but it seems that training and attitudes have not kept up. Neil Mitchell, hon. secretary of IRTE Northern Centre, says: "As a DVSA vehicle examiner, I have encountered many in-service commercial vehicles and trailers over the years with defective brakes as a result of automatic slack adjusters being faulty or not functioning correctly through poor maintenance procedures, or being incorrectly installed." |
