anchor bolt, see F1g. 5-8O.
Due to the fact that the turning centre of the se-
condary shoe lies in the anchor bolt and that of the
pr_mary shoe in the adjust1ng device, the friction be_
tween the drum and the linings will ass_st in brake
appl_cation. Also contrIbuting to this is the retard_
ing effect on the secondary shoe because of the
primary shoe's endeavour to accompany the direc-
tion of rotation of the drum __--___ v,o,,,,v,o,

3. Check that the brake pads are not stuck to the
brake disc. To prevent the lever when adjusting
from _nfluencing the shoes and thus glve m_s-
Ieading results. the spring tension act_ng on the

necting the cable from the lever
4. Set the drum so that its hole co_ncides wlth the

Then turn the adjusting screw back 4-5 serra_
