Checking The Brake Lining Wear - PRONAR T400 Operator's Manual

Pronar T400
Damaged tires or wheels can be a cause of a serious accident.
In the event of mechanical damage, consult your nearest tire service center and make sure if
the defect in the tire qualifies it for replacement.
Rims should be checked for deformation, material cracks, weld cracks, corrosion, especially
around welds and contact with the tire.
Technical condition and appropriate maintenance of wheels significantly extends the life of
these elements and ensures an appropriate level of safety for trailer users.
Pressure control and visual inspection of steel wheels:

CHECKING THE BRAKE LINING WEAR

TIP
The minimum thickness of the brake linings is 5 mm.
While using the trailer, the drum brake linings will wear out. In such case, whole brake shoes
should be replaced. Excessive wear of the brake shoes is a condition in which the thickness
of the brake linings glued or riveted to the steel structures of the shoes exceeds the minimum
value and is manifested by the extension of the cylinder piston stroke. Assessment of the
technical condition of the brake linings should be carried out through the control holes (3) -
figure (5.4).
• every 1 month of use,
• if necessary.
• Checking of the lining thickness should be carried out every 6 months.
