3.5 BRAKE PARTS
Brake shoes (Figure 42) are recommended to be replaced when
the lining thickness measures less than 2mm, as it is likely that
they will be worn out before the next service.
Always replace both brake shoes together, regardless of the
lining thickness on the other shoe. It is further advised that brake
shoes should be ideally replaces as an axle set to avoid uneven
braking from side to side.

NOTE
Please note position of sliding shoe relative to
adjuster or expander. To function correctly the
brake must be assembled in this way.
Left hand brake is a mirror image.
KNOTT COUPLINGS
Please follow the adjustment instructions in section 3.5, but do
not allow for the rearward movement of the overrun output lever,
which is only required on Meredith & Eyre couplings. All knott
couplings (Figures 43A and 43B) operate in the same manner,
so the type of housing, cast A-frame, pressed steel A-frame, or
pressed steel square-tube, is irrelevant to the brake servicing.
