Review: Solid OEM-Quality Rear Rotors at a Great Price - I recently installed the ACDelco Silver 18A2546A Rear Disc Brake Rotors on my vehicle, and they’ve performed exactly as expected — smooth, quiet, and reliable. ACDelco is a trusted brand in the industry, and this rotor lives up to their reputation. Why I recommend them: • Direct Fit – Installation was seamless. These rotors matched the OEM specs perfectly and bolted right on with no issues. No need for modifications or adjustments. • Quiet Operation – Paired with ceramic pads, I’m getting super quiet stops with no squeaking or vibration. Everything feels balanced and solid. • Smooth Braking – The braking surface was clean and true right out of the box. After a quick bedding process, the stops are smooth and confident even during high-speed braking. • Durable Build – These rotors feel well-made and have held up great under daily driving conditions. No warping or discoloration after a few thousand miles. • Affordable Upgrade – For the price, these offer excellent value. Perfect for anyone needing reliable brake performance without paying premium OEM prices. Whether you’re doing a standard rear brake job or replacing worn factory rotors, the ACDelco Silver series is a great choice. I’d definitely buy again for my other vehicles. Review: Great price, good fit and so far so good - I haven't put any real miles on these rotors yet, but they were great in price. About half what would you pay for at the retail auto stores in person. Takes some time, as always to install, but fit as they should. Side note, and I didn't feel it was worth taking stars off of the review like others may, but I received a wrong rotor in my delivery (may have been a fulfillment issue). I ended up having to go to the auto parts store when the car was on the jack to get my other side. Just make sure you get what you need, which was my mistake. It's not really worth me going through the hassle of returning it, as, again, they were so cheap. ## Features - Superior Heat Dissipation: Multi-alloy construction and application-specific vane configuration of the front rotors optimize cooling, improve performance, and reduce fading of brakes - Reduced Noise and Vibration: Rear rotor engineered with a non-directional ground finish and balanced design to help dampen noise, vibration, and harshness (NVH).

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 ### ⭐⭐⭐⭐⭐ Solid OEM-Quality Rear Rotors at a Great Price *by J***Y on July 3, 2025* I recently installed the ACDelco Silver 18A2546A Rear Disc Brake Rotors on my vehicle, and they’ve performed exactly as expected — smooth, quiet, and reliable.
