Does anybody know if you can adjust the hand brake on a 2004 voyager, 2.4l manual.

 

All "hand brakes" are adjustable. Follow the cable under the car. There should be an adjuster before it splits up going to the rear wheels. It may be covered with undercoating and may be pretty rusty. Read other posting in this section. You need to take the rear tires off and check if the adjuster is moving. It also may be rusted if not used regularly. It should spread the braking surface to the drum to work.

 

thanks for the info, I read some other posts and they talk of an adjuster under the hand brake lever. Does this apply to this model as well, I can't get under a car unless I go to a garage who will obviously charge me for it.

 

Are you talking about the control? This part ---->

I don't know what a control is, there was no picture in your link.
On other posts they mention a plastic clip fitted to the hand brake lever, I believe it was a part of the recall for the hand brake.
