II. CONSTANT EFFECT AT BEHAVIOUR
EFFECTS
Brakes not accomplishing the required
b raking distance
Vibrating brakes
When braking, the vehicle ( front part)
is left/right deviating
Braking
Heating brakes POSSIBLE CAUSES
- Non-uniform worn brake linings (backing
off);
- Brake l inings slightly gr eased;
- Springs with modified characteristics.
- Brake disks with high wobbling;
- Inconstancy brake disks width;
- Particles abnormal deposit on brake disks
(oxidation between linings and disk).
- Front axle suspension, steering (to be
checked);
- Stuck piston;
- Tires – wear, inflation pressure;
- R igid duct narrowed (flattening).
- Stuck piston;
Automatic adjustment : hand brake cable very
tighten.
REMARK :
Automatic recovering is performed by
means of the brake pedal, if there is no ab-
no rm al t ensi on in the hand brake cable
when released (hand brake released).
- Return spring.
- Insufficient hydraulic stroke of the brake
pump, not allowing the return at rest of the
brake pump pistons ( brake pump remaining
under pressure);
- St uck pistons or hardly returning;
- R igid duct narrowed (flattening);
- Def ective adjustment of the hand brake
control.

WHEELS AND TIRES

Characteristics
WHEELS
The wheels identification marking is repre sented in two ways: -engraved marking for steel rims
- cast marking for aluminum rims
The marking enables acknowledgment of the main wheels dimensions criteria.
This marki ng may be:
- Complete Example : 5.5 J 14 4 CH 43 , or
- Simplified
Example: 5.5 J 14
The wheel attachment holes are situated on a diameter of 100 mm.
Maximum axial runout : to be measured in points P1 and P2.
Maximum radial runout : to be measured in points G1 and G2.
