Interesting. So if the first stage is not tripped/worn on inspection then I'm probably safe without swapping, but if wear seen I should replace.

ARD: Yes I agree for electronics to always stay OEM. FWIW on the pads the Jurid look to be the same piece and about $60/set vs $120/set (just rears) in cost.

This is aftermarket, but I think I can see the multiple stages. I'll inspect the sensor to see if it shows wear.
