When to change a vehicle's brake rotor disk

[@MaxGiganteum]

You needed to fully examine both sides of the rotor at the friction surface for wear by default. You also check the bearings to make sure they're servicable as well as check the rotor for warpage and total runout. The reason there was more wear on one side as opposed to the other is most likely due to the caliper not freely floating thus there was more pressure applied to the inside of the rotor. Your solution may have been as simple as cleaning up and lubing the slider for the caliper and to machine the rotor after cleaning the sediment out of the vanes. Of course, you do both sides of the vehicle when servicing the brakes. Best wishes! 👍🏻👨🏻‍🔧🇺🇲 - Max Giganteum

Your concerns are well made Max, and should be considered whenever examining or changing out the pads and rotors. Please do keep in mind, that the direction of the above tutorial was to bring attention to the accelerated wear that occurs on the backside of the Rotor. The back (inner) side of the Rotor is exposed to a much different road condition then the front (outer) side. Trappings of road debri, such as salt, snow, moisture and dirt will accumulate at the rear of a wheel well, which suggests a different environment than the outer side of the rotor. In closing, the tutorials intent was to bring attention to the accelerated wear on the Rotors inner side and the reason for it. Your thoughts are always appreciated and welcomed, thank you Max : o )
