Do you need to turn rotors when replacing brake pads?
If you are not experiencing any pulsing or vibration during braking, there is no reason to turn or replace your rotors or drums during a brake pad/shoe change. As a matter of fact, you really don’t even need to “scuff” the rotors or drums, since the new brake pads/shoes will glaze…
How often should you change your brake pads?
RELATED: How often should you change your brake pads? How Often to Replace Brake Rotors. Brake rotors require replacement every 70,000 miles more or less, depending on the car model and driving style. This is far longer than brake pads which are often replaced every 40,000 to 50,000 miles.
Why do rear disc brake pads wear down?
Rear disc brake pads offer improved performance and are not affected by moisture like conventional brake shoes. Brake pads wear down making a grinding noise. Caliper slides lock up, not allowing the caliper move causing premature pad wear. Inferior parts squeak, grumble and prematurely wear. Bleed brake system after the job is complete.
How can you tell if your brake rotors are worn out?
Noisy brakes are the first sign of brake rotor wear. If the disc is uneven, you will hear squeaking noises from the wheels. Warped rotors produce a squeaking sound, while extremely ramshackle rotors produce a scraping sound.

Step 5 – Using a pair of dikes remove the rotor retainer clip which is used in initial assembly and will not be reinstalled. Step 6 – Next, use a socket to remove both upper and lower caliper mounting bolts. Use a wrench if necessary to secure the slide.

How often do you change the rotor on a BMW?
The service intervals are so limited that BMW recommends ‘replace rotor when pad is replaced’…this way they KNOW you can not get to a position where the pad is good, the car thinks the brakes are fine, it is telling you you have 20,000 more miles, yet the rotor is down below the safe limit. When BMW is paying, replace both.
When you are paying, pay attention to how many miles you got on the pads, how thin the rotor is, and make a guess accordingly. For example lets say you get 26,000 miles and the pads are at 3mm (wear limit is 2mm IIRC)…measure the rotors. If the rotor is 31.2mm (ie you’ve used 0.8mm) then you are fine.
