the tappets and their rests in the brake disk (spare washers are not
supplied by the manuf acturer) .
The brake is assembJ, ed in the following succession:
ins ert the c <~ ms in the disk openings;
hook return spring 9 in the disk opening;
fit the shoes with springs on the ta 1 ppet spherical ends and on the
caun bearing surfaces;
install and fix the driving and driven levers on the
cam splines maintaining the size of 82:b5° as illustrated in Fig . 27.
The parallelizm of levers . should tbe within 5°.
Upon fitting the brakes on the motorcycle connect th e rod wit h
the driving lever. Turn each lever clockwise ti.U the shoes thrust
aga inst the wheel brake drum .
By turning the rod out/in the fork adjust the distan ce bet - ween
the f.ork holes centers so that the pin connecting the fork with the
driven lever freely enters the holes of the le ve r and fork.
In this case the rod should screw in the fo rk for not less than
5 mm. At the e nd w here there is no lock nut the fork should be scre-
wed onto the rod up 'to the end of thread. Cotterpin the rod in
the fork, connect the · rod with if: he dri ve n lever and cotteroin
the joint. ·
Wind up the return spring. If the above assembling requireme nt s
are observed and necessary conditions for the reliabl e operation of
the brake at the expence of simultaneous pressing of both shoes to
the wheel br ake drum wil1 1 be pr ovi ded .
When assemlbling the brake ca re should be taken to fit the sho es
in their former places, otherwise their wear-in will lbe disturbed a nd
for some time the effici·ency of the br ake will be poor.
It is also necessary to pay a tte ntion to the cam surfaces a. gainst
which the shoes thrusted since the ca m su rf aces are asymmetrical
with respect to its axis of ro tati<o n. Both shoes must rest on the cam
planes equally offset · relative to the pin.
The
brake should be adjusted in the course of run as required by
turning out the adjustin g union as desuibed above.
The ad ju stme nt over, cotterpin the union .
Adjust the brake on a mo tor .cycle so th at the raised wheel freely
rot
at es wit h out brushing against the blocks an d during braking the
required effectiveness an d conven ien ce of gripping the lever with the
hand is obtained .
For the sake of safety try the braking efficiency at low speeds.
Lubricate the br akes in accordance with the instru ctio ns cited in
t
he Section "T echnical Servicing" .
After washi ng and lubri · cat ing the excess oil mu st be removed to
prevent oiling of the lini ngs.
