You may be asking yourself, “Will new rotors make noise?” If so, you should take your vehicle to a mechanic. Here are some possible reasons for the noise:
Symptoms
If you hear a squeaking or grinding noise when you brake, the problem could be a warped or bent rotor. Warped rotors are likely to be the culprit. They need to be greased so they can properly contact the brake pads. If this noise is isolated to the brake pedal, it’s most likely a warped rotor. This problem should be addressed as soon as possible.
Causes
There are many reasons why your new rotors are making noise. This noise could be caused by your rotors scraping against each other while you’re driving. You could have pebbles, rocks, or rust in the brake rotors that are scraping your rotors. Or your backing plate may be bent and rubbing against the rotor, making a noise. If you notice this noise, take your car to the mechanic who did the work.
Fixes
If you’ve recently had your brakes replaced, you may have noticed a scraping noise from your rotors. This can be caused by pebbles or rocks on your road, or it can also be the result of a rusted backing plate. Regardless of the cause, there are a few different fixes for new rotors making noise. Listed below are a few common fixes.
Cleaning
If your rotors are black, they’re probably dirty. This doesn’t happen naturally. Black rotors are actually just burned contaminants. While this noise is usually temporary, it is a red flag. You can clean them yourself using a clean rag or brake cleaner. When you’re done, the brakes should sound metallic brown. After cleaning, test the brakes to make sure they’re working.
Alignment
If your brakes are making noise, your new rotors are likely out of alignment. Your new rotors may be out of alignment by more than a degree, which can result in a lot of noise and unsteady driving. The most common cause of this noise is rust and warped brake rotors. You can easily check for rust by removing the caliper and inspecting the brake pads. If you notice rust or glazing on the pads, replace them.
Glazing
You might be hearing an odd noise from your brakes every time you stop. If so, you may be dealing with glazed brake pads or rotors. Brake pads that are too hot to touch and wear can result in glazing on the parts they contact. This will make your brakes noisy and lower the coefficient of friction, causing a loss of stopping power. If you suspect glazing, get your brakes checked by a professional mechanic.
Dust buildup
There are several reasons why your brakes are making noise. First of all, brake squealing is most likely a sign of excessive brake wear. This is caused by water being absorbed by the rotors, which causes a thin layer of rust to develop on the rotor’s surface. This layer will then be scraped off by the brake pads, causing a noise. While it may seem annoying at first, this squealing typically disappears after driving a few miles.
Unlubricated brake mounting hardware
A third and fourth reason for brake noise is unsealed rotors. Likewise, if the brake mounting hardware is unlubricated, you will hear noise when new rotors are installed. The first step is to lubricate the hardware, which will help to eliminate noises from the rotors and mounting hardware. The next step is to check the rotors to make sure that they are clean and free of debris.
