DRUM BRAKE
Install brake anchor plate (or exchange it):
• Place thrust washer (8, Fig. 10) over the
axle on the adjusting cone and fit
complete brake anchor plate. Position
washer (9) distance sleeve (10) and
screw on locknut (11).
• Push brake lever (7) to the stop and hold
it there to center the brake jaws in the
brake drum – tighten up locknut with a
torque of 15 – 20 Nm (133 – 177 in.lbs.).
ADJUSTMENT DRUM BRAKE
• Unscrew adjusting screw (2, Fig. 10)
until the brake pads drag lightly.
• Actuate the hand brake lever forcefully
several times and then, if necessary,
turn the adjusting screw further in just
until the wheel starts spinning freely.
• Lock hex nut (3).
Caution:
Check that all the brake system
components are functioning properly!
MAINTENANCE /
LUBRICATION
Caution:
The SRAM hubs are provided with
permanent lubrication and under normal
conditions is maintenance-free. If the
coaster brake is loaded excessively its
effect can be too strong, the hub may lock.
In such a case the 3 brake segments should
be lubricated with a special grease (Part
No.
0369 135 200/ ...201)
. Renew brake seg-
ments when rhombic pattern is worn out.
Cleaning of parts:
• All parts – except for the planetary gear
carrier – can be degreased in a cleaning
bath.
• The planetary gear carrier only needs to
be cleaned on the outside with a brush
so as not to degrease the planetary gear
bearing.
Caution:
Do not use high-pressure water when
cleaning the gear hub (e.g. strong water
jets, high-pressure cleaners etc.) –
if water penetrates it could lead to
functional problems.
Lubrication of parts:
Use only SRAM grease (Part No. 0369135 200/
...201) and standard bicycle oil.
• To lubricate the bearing points on the
planetary gear sets, position the plane-
tary gear carrier on its crown and apply
2 – 3 drops of oil to the bearing bolts –
at the same time turning the planetary
gears so that the bearing points are
completely wet. Oil axle through the axle
bore and axle slot, apply a thin coating
of grease to the outside.
• Oil the inside of the sun gears, grease
the outside teeth (fill the gaps in the
teeth).
• Oil outside teeth and carrier plate on
the coupling gear and lightly grease the
borehole from right and left.
• Do not apply grease to ring gear but just
oil the pawl pockets.
• Slightly grease the actuation ramps of
the planetary gear carrier.
• Apply grease all around the seat area of
the friction spring. Oil the pawl pockets.
• Spread grease on the complete surfaces
inside and outside of the 3 brake seg-
ments.
• Regrease ball retainer and insert into
lever cone, slightly grease cone surface
of the lever cone.
• Line ball bearing running tracks and
brake cylinder in hub shell with grease.
