Do not over adjust. Make sure that the wheels turn without the brakes grinding after adjustment.
Brake drums should be opened every 3000 miles, to clean the inner parts of the brakes. The
armature plate with brake pads and straddle mechanism can be pulled out after first having
removed the front wheel. This task is a little more difficult for the rear brake. After having taken out
the rear wheel, rubber housings of the chain need to be removed from the cover plate and taken
off. Then the master link of the chain is to be opened (Make sure to leave the chain in the rubber
housings). After loosening the axle nut and the brake retainer screw, the entire rear wheel hub
including chain and rubber housings can be removed. The three screws of the chain housing are
taken out and the housing lid removed. The sprocket wheel is pulled out after the three nuts have
been taken out. Afterwards the armature plate can be pulled out, revealing the brake mechanism.
By removing the three countersinks, the brake drum can be removed.
All inner parts are to be thoroughly cleansed, the brake pads checked for wear and immaculate
adhesive sealing as well as the right bevel on their ends. All pivot points and spring loops are to be
lubricated

Simultaneously the hub´s ball bearings are to be washed out in fuel and regreased afterwards.

also be used as front wheel and vice versa.
