To obtain a correct and constant braking force, a clearance check and possible adjustment of the parking brake has to be carried out every 500 hours.
1 Park the combine on level ground and block the wheels adequately to prevent the combine from moving.
2 Raise the header and engage the header safety latch. Stop the engine.
3 Remove the guard from the end of the parking brake shaft.
4 Measure and record the shaft protrusion distance.
5 Manually release the parking brake, refer to “Manually Releasing Parking Brake” in this section.
6 Measure and record the shaft protrusion distance.
7 The difference between the measurements from step 4 and 6 is the piston travel.
The piston travel must fall between 1/8” – 3/16”. If the travel is less brake drag may occur, if travel is to great reaction time will be excessive.
8 Loosen bolts (2) and adjust the quantity of shims as required. One shim will provide about 5/64”. Place the removed shim under bolts (2) for future use.
9 Recheck the piston travel by performing steps 4 through 6.
