husqvana 345 Brake issues

[Skyveiw]

evening all

 

i would post a video i record but it too large so i try and describe my issue. Every time i go to disengage the break on my saw the side plate move out and off the chain brake handle. i have to physical hold it against the handle to allow the break to be released. at first i thought it was the spring but i clean that and it still occurs so i use another saw side panel and it work fine so i am at loss at what wrong any idea?

What can happen is the quadrant in the hand guart itself wears, it then no longer fits deep enough into the brake cover making near imossible to load the brake, so change the hand guard.
