Replacing blade clutch pad on Husqvarna push mower

I have a Husqvarna HU775BBC mower which has been a solid workhorse for my home.

Its however almost to bare metal on the brake puck that stops the blade from spinning, letting the mower idle when the blade clutch bar isn't engaged.

I've searched hi and low and am unable to find a replacement for this particular component which looks like it's simply a brake puck on a plate that is rivited to the main assembly but am only able to find the whole assembly at near $200.

I've replaced the entire part before when it was available for $75 but at 175 I may as well get a new mower.

Attached is a link to the whole component, which you can see the brake puck and it's plate towards the middle of.

I'm hoping there's a replacement part I've just not been able to find.
Other options are trying to do a sketchy repair with a modified brake puck and epoxy or sending the plate to a specialist?

I see it for less on a couple other sites but you could try your thought of JBweld and a new block maybe cut off a brake shoe or something.

Once it gets to bare metal, I'm thinking of getting a riding mower brake puck, cutting it and then epoxying it to the plate.
$150+ is the point i'd just get a new mower as this one is getting up there In age and this part is consumable.

I may also try to find a broken Husqvarna from the same series and swap out the parts that control the blade clutch for one that requires the blade bar is engaged to stay running.

I have this same mower and was looking for other when i bumped into this. I haven't studied exactly how the BBC works, but I did run across the following website when looking for common bearing sizes for the wheels. So I registered here to post this for you. This guy is using common bearings when rebuilding the BBC, but I'm not sure what other things he did. Maybe he can assist.
Take care.
