The brake is activated by pushing the foot brake pedals in the tractor cabin. For that
reason, the brake can only work when the hydraulic hose is connected to the tractor
properly and the tractor engine is running.
Performance of the brake chamber cylinders
The brake chamber cylinders activate or deactivate the drum brakes. If the pistons of
the brake chamber cylinders bottom out, the brake performance may fail completely.
Possible causes are damaged or worn brake shoes and/or defective joints or improper
adjustment.
Maintaining and servicing
A maintenance service in a professional workshop is necessary when:
The brake performance is reducing continuously and/or
The brakes squeal or grate heavily when activating the foot brake.
10.14.4 Brake adjustment
Machines fitted with brakes, either air or hydraulic, must be initially checked after the
first 50 hours of use and every 100 hours or yearly thereafter (whichever comes first).
WARNING: Must be qualified to work on the brake drums
This work should only be carried out by qualified persons or your
McHale
dealer, who are familiar with braking systems.
WARNING: Ensure safety before working on brake adjustment
Before attempting to carry out brake adjustment, ensure that the tractor
engine has been switched off and the key removed. Testing should be
conducted with the hand brake ‘off’ on both the machine and the tractor
and a second trained person will be required to activate brakes from the
tractor. Also ensure machinery can’t roll by parking machinery on level
ground with wheels chocked. Always wear protective clothing and
gloves.
