can anyone tell me how to adjust hand brake

[2015 Z Force 800 53/Trail EPS]

The U Forces are a little different and I'm sure the service manual shows you how. We have it here free under the UForce 800 section.

Mine had a lock nut come loose next to the lever in the center console. It was a bear to get at with all the plastic and ended up taking it to the dealer for them to adjust and tighten up all under warranty.

can anyone tell me how to adjust hand brake

Yes

can not seem to find out how to adjust hand brake in service manual

There's an adjustment on each rear brake caliper and another under the center console.

Cannot do attachments for some reason  don't know if I'm not pushing the right buttons or it just doesn't work.

You have cable adjustment on each caliper & a bolt with a lock nut on each caliper to adjust the pads. With the wheels & tires off & the rear & elevated so you spin the hubs, slack the cables right off. Then loosen the lock nut, lift the park brake lever two clicks & adjust the bolt by hand until you feel the pads begin to drag as you spin the each hub. Back the bolt 1/8 turn once you feel it drag & lock the nut, you should have zero drag.

At this point I like to use a feeler gauge & verify clearance between the pads & rotor, usually in the area of .010

Still with me 

Remember the brake lever is two clicks up, adjust the cable until you feel a very slight drag each side. Release the brake lever, you should have zero drag. You can verify your feeler gauge measurement with the park brake released.

Very important to insure no drag
