Handbrake

Adjustment

The transmission brake is normally adjusted with the cable adjuster at the cab end of the cable. To adjust, firstly chock the wheels and ensure the brake lever is off. Then adjust the nuts on the cable end fitting whilst someone rocks the brake disc for you, until the pad starts to drag on the disc. Then back off a small amount until it clears.

When you run out of adjustment, the cable should be screwed back in at the cab end and the cable support bracket on top of the brake assembly can be moved to the end of its slotted mounting holes after slackening the mounting studs. (B). After retightening the cable can be re-adjusted at the cab end.

If more adjustment is still required before the pads wear out it is possible to move the actuating arm position. Back off the cable adjustment, unbend the tab on the anti-rotation clip (A) and loosen the bolt enough to disengage the lever spline. Rotate the lever one tooth anticlockwise and retighten the bolt making sure the spline teeth are properly engaged. Bend up a tab that aligns with one of the bolt head flats. Then readjust at the cab end of the cable as above.

Lubrication

It is most important that the calliper assembly is kept clean and well lubricated. Oil all moving parts regularly particularly when the PHANTOM is being used to spread fertiliser.

A grease nipple is also fitted into the operating cable approx 300mm up from the brake calliper. This should be greased weekly.

Pad replacement

Check the friction pads for wear regularly and replace if necessary. To check for wear, measure the distance from the carrier side casting to the rear of the disc face. This should not be less than 1.5mm.

To replace the pads remove the locknuts from the two main calliper mounting bolts (C), remove the bolts and the calliper assembly. The old pads can then be prised out and replaced with new ones. Reassemble and readjust as above.
