SECTION 5 

5.14 

  Install the brake cylinder fork pin and washers and secure the pin with cotter 

pins. 

  Rotate  adjustment  bolt  (4)  to  the  right  until  one  or  two  clicking  sounds  are 

heard in the expander arm regulating mechanism. 

  Repeat adjustment activities for the other brake cylinder on the same axle. 

  Engage the brake. 

  Remove previous marks and measure the brake cylinder piston stroke again. 

  If the brake cylinder piston stroke is outside the proper operating range, repeat 

the adjustment. 

 

 

•

 

Every 6 months. 

•

 

After repair of braking system. 

•

 

In case of uneven trailer wheel braking. 

 
 

IMPORTANT! 

 

The positions for fixing the brake cylinder in the bracket openings and the brake cylinder 
pin in the expander arm are determined by the Manufacturer and must not be changed. 

Each time when dismantling the pin or brake cylinder, the original fixing position should 
be marked. 

5.2.8  CHANGE OF PARKING BRAKE CABLE AND ADJUSTMENT OF CABLE 

TENSION. 

Proper  operation  of  the  parking  brake  is  dependent  on  the  effectiveness  of  the  axle  brake 

and the correct brake cables tension. 

Before commencing adjustment  make certain that the main break is correctly regulated and 

is functioning properly. 

Adjustment of parking brake cable tension should be conducted in the event of: 

•

  stretching of cable, 

•

  loosening of parking brake cable clamps
