Adjustment Of Mechanical Brakes - PRONAR T663/1 Operator's Manual

Pronar T663/1 T663/1 SILO
TIP
Tyre pressure values are specified in information decal, placed on wheel or on upper
frame above trailer wheel.
DANGER
Damaged tyres or wheels may be the cause of a serious accident.
While checking pressure pay attention to technical condition of wheels and tyres. Look
carefully at tyre sides and check the condition of tread.
In case of mechanical damage consult the nearest tyre service and check whether the tyre
defect requires tyre replacement.
Wheels should be inspected with regard to distortion, breaking of material, breaking of welds,
corrosion, especially in the area of welds and contact with tyre.
Proper technical condition and appropriate maintenance of wheels significantly extends the
life of these components and ensures appropriate level of safety to trailer users.
Checking air pressure in tyres and visual inspection of steel wheels:

ADJUSTMENT OF MECHANICAL BRAKES

During trailer operation drum brake linings are subjected to wear. Piston stroke extends and,
after exceeding the limit value, braking force declines.
Adjustment must be made when:
• piston rod stroke amounts to 2/3 of maximum stroke,
• expansion levers are not set in parallel to each other during braking,
• repairs are made to braking system.
• every 1 month of use,
• if needed.
