Kontrol af bremseskivens sidekast | HELLA

GenereltFor så tidligt som muligt at forebygge problemet med bremseruflen under kørslen bør nye bremseskivers lige løb kontrolleres med et passende måleur. Kontrollen af sidekast foretages, mens bremseskiven er monteret. Her gælder bilproducentens modelspecifikke angivelser.Vejledende værdi: Maks. tilladt sidekast 0,07 mmKontrolFølgende fremgangsmåde anbefales.Monter bremseskiven med alle hjulbolte eller hjulmøtrikker og tilhørende underlags- eller afstandsskiver på hjulnavet iht. forskrifterne.Fastgør en måleur med holder på fjederbenet.Sæt målespidsen mod skiven ca. 10-15 mm inden for skivens yderkant, og sæt uret på 0.Drej bremseskiven i kørselsretningen.Aflæs og noter måleværdierneVariationerne, målt over flere omdrejninger, må ikke overstige de pågældende tolerancer!ReparationsanvisningDenne kontrol gælder kun for bremseskiver, der er nye eller så gode som nye.I tilfælde af større afvigelser skal tilstanden af hjulnav og lejer tages i betragtning som yderligere fejlkilde.I den forbindelse skal bilfabrikantens vedligeholdelses- og reparationsanvisninger altid følges.

In order to avoid the problem of brake judder when driving as early as possible, the axial runout of the new brake disc should be tested using a suitable dial gauge. The check of lateral runout is performed with the brake disc installed. The vehicle-specific specifications of the respective vehicle manufacturer are binding.

Guide value: Max. permissible lateral runout 0.07mm

Tests

The following procedure is recommended.

Install the brake disc on the wheel hub as prescribed with all wheel bolts or wheel nuts, and the corresponding washers and shims.
Fasten the dial gage with holder to the suspension strut.
Place the dial gage approx. 10 - 15 mm below the outer radius of the disc and align with 'zero'.
Turn the brake disc in the direction of travel.
Read off the measured values and note

Measured over several wheel revolutions, deviations should not exceed the respective tolerance values.

Repair note

This test should only be carried out on brake discs that are new or like new.
If deviations are found, the state of the wheel hub and bearing should be considered as further fault sources.

Please always observe the specifications in the maintenance and repair notes provided by the respective vehicle manufacturer.
