Should I change my rotors when they are rusty?
Should I change my rotors when they are rusty?
A. Brake rotors will rust. Usually it’s just surface rust that will wear off after a couple of miles of driving. If the rust is deep — to the point of pitting — it is certainly possible the rotors need to be replaced.
Why are my new rotors rusting?
The nature of disc brake operation is such that the friction pads constantly wear away at the surface of each rotor. Each time you park your car, the freshly minted surface of each rotor is exposed to the elements. As you have discovered, the fresh unprotected cast iron will begin rusting almost immediately.
Is it possible for brake rotors to develop rust?
I would get a second opinion. It’s quite possible that your rotors have developed rust in that time. However, if they resemble the rotors in the picture that you provided then they should still be fine. That rust appears to be the same kind that develops inevitably over time with use.
Is it true that turn rotors are true?
The only real case to “turn” rotors true is if you have some 50’s classic (Buick with aluminum finned drums anyone?), or a large truck, wherein replacement rotors are exorbitantly expensive. So, to summarize, if you brought this car to me, and you had decent pad thickness, I’m not in the business of ripping you off, so I would send you on your way.
What happens if the rotors are missing on a car?
Missing rotor material means the pistons travel out beyond what they were designed to, which can damage seals, and even sieze/ruin a caliper. I’m just summarizing what has already been said by some very erudite folks and throwing on my own never-humble spin.
Is it possible to avoid replacing brake rotors?
It is possible to use a lathe to true up a rotor and avoid replacing them, but new rotors being so cheep it often doesn’t make financial sense. That does not say for sure if you are being ripped off in this situation, but it is totally reasonable to expect to need to replace these parts if the car was sitting for a year.
