Should I machine or replace rotors?

A rotor must be replaced if it is worn down to minimum specifications or the discard thickness, or cannot be resurfaced without exceeding the minimum “machine to” specification. These specifications are usually cast or stamped on the rotor, and can also be found in brake repair manuals.

How much does it cost to machine your rotors?

between $250-$325
Most shops charge anywhere between $250-$325 to machine rotors and replace one set of pads per axle.

Do rotors make noise after replacement?

Due to getting new rotors, you will want to make sure the correct replacement rotors have been used. Check the wheels and brakes for excess brake dust. This will also make a squeak, but again, a grinding noise is typically metal on metal, or brake pad stuck.

How long do machined rotors last?

Your rotors are one of the most durable parts of your car, but the above factors can shorten their lifespan. Expect your rotors to last anywhere from 30,000-70,000 miles depending on the above factors.

How do I know if my rotors need machining?

If your rotor surface is smooth there is generally no need to have them turned. If, however, you have warping, or rough spots they should be turned, or replaced if need be. This is easily detected if you have a solid, non-pulsing braking action when you press down on the pedal.

Why are my new rotors grinding?

There is Debris on the Brake Pad or Rotor Another reason why your car may be grinding is that there is debris on your brake pad or rotor. This debris may be something like dirt or dust or can even be rust. If a mechanic sees debris on the rotor when they are replacing the pads, they should clean it or repair it.

Why are my new rotors squeaking?

One of the most common reasons that new brakes squeal is that there’s moisture on the rotors. When they get wet, a thin layer of rust will develop on the surface. When the pads come into contact with the rotors, these particles get embedded into them, creating a squealing sound.

How many times can you resurface rotors?

Even resurfaced rotors need to be replaced every 70,000 miles, doesn’t matter that they are in good working condition. Look for signs of uneven wear, excessive runout, and heavy pitting, spotting, grooving, hard spots, or cracking.

How much does it cost to get rotors resurfaced?

Resurfacing cost per rotor can vary widely. If you remove your rotors yourself and take them to a shop or parts store for resurfacing, the cost can range from as little as $15 to over $45 per rotor. To have a repair shop remove, resurface and reinstall your rotors can cost up to $100 per wheel, $400 for the whole car.
