Adjustment Of Mechanical Brakes - PRONAR T669 Operator's Manual

SECTION 5
TIP
Tyre pressure values are specified in information decal, placed on wheel or on upper
frame above trailer wheel.
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.
DANGER
Damaged tyres or wheels may be the cause of a serious accident.
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.
Technical condition and appropriate maintenance significantly extends the life of these
components and ensures appropriate level of safety to trailer users.
Checking tyre pressure and steel rims:

5.2.8 ADJUSTMENT OF MECHANICAL BRAKES

During use of trailer abrasive friction covering of brake drums is subject to wear. Piston
stroke extends, and exceeding braking force limiting value declines.
Adjustment must be made when:
• piston 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.
