Svieta spends most of her time standing outdoors, gets driven about once a week, and even then doesn't get much brake usage (my rear pads were replaced 4 years ago and are barely used). This was bound to happen sooner than later, so each time I used the car I would use the brakes much more often than necessary, but even that didn't help much.
Last November inspection saw the rust on the brake rotors and the only reason I passed is because my mechanic was there and promised to replace them. I waited until after winter to do it.
It turned out that they looked OK from the outside, but the inside was a tragedy: the mechanic said it looked like someone had poured acid on them:
We are still wondering what to do with the rear rotors, since they are integrated with the wheel bearing, which triples the price
Hopefully everything will be done by the end of the week and I'll if there is a difference in coasting.
Also, I wonder if covering the wheels while parked would have a measurable effect? The way the car is parked one side gets lots of sun, the other gets none, both get regularly peed on by our dog and the neighbor's cats
