3. ADJUSTING THE BRAKES
The motorcycle full width hub brakes are well dimensioned and are fully shielded
against water penetration which would reduce their efficiency. The brakes require
only occasional adjustment when the brake shoe lining is worn (excessive brake
lever stroke).
The brakes are adjusted by turning the adjuster nuts. Having adjusted the brakes
check the wheels for free rotation. With the rear brake the stop switch has to be
adjusted as well - see pars 8.
4. TYRES
The life of the outer tyre cover depends on the inner tube air pressure in relation
to the load carried. As a rule the tyre has to be inflated so as to keep its original
shape even under full load. Running on under-inflated tyres will result in the
cover wall cord threads breaking.
Rim and tyre - sectional view - fitting the tyre cover
The pressure in the front tyre should be 18 lb. sq. in. (1.25 atm.), in the rear tyre
21 lb. sq. in. (1.5 atm.), with pillion rider 28 lb. sq. in. (2 atm.). It is advisable to
check the pressure with the tyre pressure gauge. It is a well known fact that the
tyre pressure increases during long rides in hot weather. In cold weather, on snow
or icy roads partly under-inflated tyres will be of advantage for better control of
the machine. In addition
