I bought a 540iXP (rear handle, battery) in late 2024. Just over 1 year later, the brake band broke. The replacement lasted about as long; this past weekend I found it broken again.

This pic is the 1st break; the 2nd one broke about 1/8" / 3 mm more to the left (away from the curved end). So both times in the same general area.
I did do the repair myself rather than paying the dealer; I'm no expert but not an idiot at the workbench so I don't think I could have done anything wrong there.
This saw sees an intermediate amount of use -- less than by most pros (I expect) but much more than by a typical homeowner. I am not a pro myself; 98% of my chainsaw work is as a volunteer removing invasive and other undesirable brush and trees as part of ecological restorations, averaging ~3 hrs a week. At the time of the 1st break it had recorded between 20 and 21 hours of motor run time out of about 100 hrs of power-on time; running time is probably around 45 hrs now.
I don't *think* I'm using it improperly. I've had multiple chainsaw use & maintenance training sessions, including one from our states' ISA chapter. I *am* constantly dis-engaging and then re-engaging the brake between cuts, but I do wait til the chain has almost stopped; I'm not slamming it on while under power. So the brake almost never gets engaged while the saw is actually running; maybe once every 2-3 months, typically when I'm working in a tight area and catch the arm on something. So I don't feel like I'm asking a lot of what is supposed to be a durable product.
Has anybody else seen this? Is there anything I could possibly be doing to cause it? Are Husqs, or at least their battery saws, known for short brake band life?
Thanks for any insights. I'm buying several replacements; guess I have to start stocking this as a consumable :-(
