Adjusting Pilote Galaxy 270 handbrake.

[68c]

Trying to adjust the parking brake on my Pilote Galaxy 270. Advised to remove one wheel bolt, jack up wheel and adjust through bolt hole.
I used my cheap little endoscope to locate the adjuster. Tried to move it with a screwdriver without success. Is there more to it, which way do I adjust it. Photo shows left wheel. Shoes and adjusters were replaced last year.

Edit. It is an A Class with Alco chassis, based on a 2001 Peugeot Boxer 320mwb.

Try moving it both ways with a longer driver. If it does not move it needs to come off to find out why.

I think your right, annoyed as adjusters and shoes only a year old.
