In time, that material wears away and the pads/shoes must be replaced. Sometimes the rotors and drums also must be replaced. **Q: What’s the squealing sound I hear when braking?** A: Over time, wear indicators in brakes pads may contact the rotors’ surface when braking, resulting in a metallic squealing sound. Vehicles equipped with wear sensors may also provide an alert that minimum brake pad thickness has been reached. **Q: What if it’s more of a grinding sound?** A: If all the friction material has been worn away, the metal backing plate of the brake pad will be the material in contact with the rotor during braking. It causes a grinding sound and braking performance is often diminished. **Q: What if it’s more of a grinding sound?** A: If all the friction material has been worn away, the metal backing plate of the brake pad will be the material in contact with the rotor during braking. It causes a grinding sound and braking performance is often diminished. **Q: What about vibrations or shaking in the steering wheel?** A: This is more serious than pulsation. If the brakes are very worn or the rotors are warped, there can be a significant vibration or shaking in the steering wheel when braking. It may mean brake service is needed immediately. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good and Inexpensive *by B***N on Reviewed in the United States on September 21, 2023* There really is not much to say other than they seem to be quality and are much cheaper than other name brands (surprising as they carry the AC Delco name). I've got a few hundred miles on them and no pulsations, etc. So far so good. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Rotors are well machined *by D***G on Reviewed in the United States on June 14, 2023* No brake vibration or noise. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Not coated and rust by looking at them. *by A***S on Reviewed in the United States on December 8, 2021* I could not get the coated rotors, so I bought these. They fit and work great. The price was quite good. However, they rust just by looking at them. If you rotors are overly visible, you may want to wait until you can get the coated rotors. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/14858408-silver-18a2821a-88878112-non-coated-rear-disc-brake-rotor](https://www.desertcart.hr/products/14858408-silver-18a2821a-88878112-non-coated-rear-disc-brake-rotor) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
