The dealership says my sister's rotors must be replaced 'because they're
rusting'.

The CR-V has 60,000 km on it. Is this normal wear?

Your expert opinion is invited... thanks, Jack.

Ha. Rust on the brake rotors' circumferences by itself are not detrimental
to the rotor's operation and is expected.

Ask them about the rotor's thickness and thickness variation, for starters.
Did they measure it? What's the spec? Make them elaborate a lot more than
they are simply "rusted."

60k km is ridiculously early for a rotor to ordinarily need replacement.

My 91 Civic is on its original rotors after 270k km. Granted, I do a lot of
engine braking, and one rotor is a bit scored. The thickness is great,
though, and I expect them to last the life of the car (like five more
years).

Others will post...

Rotors are iron.

They rust.

Do this: let the car sit in damp weather for a weekend. Go out and
look at the rotors.

Drive the car. Listen to the brakes for the first few stops. That's
the sound of the rust grinding off.

Perfectly normal.

Hah hah. Potamkin in NYC, by any chance? Or another crook? They said
that about mine (94 Civic), too, and when I got a look at them I
laughed. Not in the guy's face--though I should have--because I was
standing there with the seller and it was a pre-purchase checkup, but I
did laugh privately later... (with the seller cuz I'm an honest guy)

Elle and Elmo are right on.

60K km (40K miles) in how many years? You haven't provided that, and it's
crucial.

You're obviously in Canada, but I don't know where. Northeastern Canada is
the very worst place for brake rust on the planet.

The less you drive, the more rust forms, and the sooner they need replacing
relative to your mileage. Elmo is right.

Thanks for your insight.

Location - Ottawa. I think my sister's CR-V is about 2 years old.

Thanks again for writing - Jack.

That's not surprising. I get similar mileage too with mine. Can do
Dallas-Houston-Dallas on one tank easy.

Well, it sounds like he is coasting a lot and letting his speed drop
when going up hills also. If you really game the system, you will beat
the cruise control. After all, you can see what's coming up next, and
it can't. It also sounds like he's making his fellow drivers nuts by
going 50 mph and getting in their way. Austin traffic is hellacious,
and I wouldn't want to be behind this guy so he can save $10 a month.

You'd think so, but experimentally, in a lot of different cars doing
economy runs, its not. Cruise control is just to keep the car at a
constant speed, no to do it efficiently.

So you're keeping your throttle at exactly the same position, manually,
and if you go up or down a hill and your speed changes dramatically, so
be it?
