Uneven rotor wear on 2018 Standard Model 3

[Spirit]

Brakes are functioning properly and pads do not show much wear, but on tire rotation found 30-50% of discs surface were not being used. Thought I'd cleand lube the sliders, but don't see how to access them like a traditional car. Will I be able to remove the caliper and access them with typical garage tools?

I am exploring a similar problem because a bloke comes up to me in the Supermarket car-park at the weekend and tells me my brake discs are not correctly wearing (he claims he is a Motorhead and knows these things). Ok, so I start to have a look myself and compare the discs on my car to other cars including another Tesla. All 4 of my brake discs are showing an even wear pattern where by only 30%-50% of the disc surface remains shiny. The car is a Model 3 2019 Performance.

I am no expert in these matters. My car has done 55,000 miles and to have to replace the brake discs seems a bit odd. I am aware that regen braking can mean the brakes tend to do a lot less work than ICE vehicles however they should still evenly wear but just last longer... Well that is what Tesla sales tell you anyhow... Did you get to the bottom of your issues. Interested in your feedback? My car doesn't do a lot of mileage, could it be corrosion? Is it a problem, could it affect upcoming MOT. I have not noticed any braking problem but then I don't go round needing to hit the brakes very often.

I have a Model Y - 20months old and the brake discs on that are shiny as they were new. It doesn't make sense at all....
