OVERSIZE (8″ Brakes)
The standard 8″ adjuster cam is NLA. These oversize cams are deigned for
use with skimmed drums to return the normal range of adjustment. At the
the lowest adjustment setting they are 1/8″ taller. To use with
standard drums and new shoes you may need to slot the brake shoes to
allow the drum to fit over.
The actual snail cams don`t usually
wear out, they are not meant to be sharp ! The retaining mask FBK111 is
more likely to need replacing. If you cannot get the correct shoe to
drum adjustment you will need to change the shoes or the drum or both.
