                                             PRODUCT WARNING
           Safety risks resulting from incorrectly reconditioned
                         Knorr-Bremse disc brakes
    Increasingly we are seeing disc brakes, calipers and service parts in the market that have been
    reconditioned b y the company Trucktechnic S.A. Herstal, Belgium. Products of this company are
    offered to service the Knorr-Bremse SB and SN types of disc brake.

    by this company is not approved or aubhorbd by K m 8 r m # I


     The company Trucktechnic dbmanttes used dlsc brakes and, from evidence seen, uses old parts
     for the reconditioning that should not be mused. The reconditioned product is then offered to the
     market with no indication that the quality k not equal to that of an original Knorr-Bremse product.
     Knorr-Bremse has found several exampks of safety-related failings in Trucktechnic assemblies
     which did not match the original Knorr-Bremse product specification and could have led to
                                   dangerous situations in traffic.

    Examples of safety-related failings found:
                         Unsatisfactory sealing against the                               The reuseof highly stressed screws can

                         the rapid corrosion of precision parts
                         inside the caliper. This can lead to
                                                                                      I   resutts in an imrnediie loss of braking

                         sticking of the brake mechanism and
                         even 'locking on' of the brake, as

                         automatic wear adjuster and wear                                 parts of unknown origin, as well as
                         indicator.                                                       unsatisfactory synchronisation during
                                                                                          assembly of the brakes, resutts in a
                                                                              3           replacement brake with a high risk of
                                                                                          failure.
    How can a Trucktechnic reconditioned brake be recognised
    and how does it differ from an original Knorr-Bremse disc
    brake?
       The Knorr-Bremse logo is still present on the brake
       caliper casting, however the original Knorr-Bremsepart
       number label is replaced by the Trucktechnic label.

The originalmanufacturerof a product has the know-how which is crucial for the sak and correct function of that
product, including the complete functional testing of all subassemblies and the final assembly, to ensure it will
meet the specifiedperformance levels thmughout its requiredlife.
