In time, that material wears away and the pads must be replaced. Sometimes the rotors and calipers must also be replaced. **Q: What’s the squealing sound I hear when braking?** A: Over time, wear indicators in brake 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: Why do the brakes seem to pulsate when stopping?** A: It may be due to worn brake pads, unevenly worn rotors or unevenly worn tires. Have the pulsation diagnosed as soon as possible to avoid the possibility of greater brake system wear or damage. **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 unevenly worn, there can be a significant vibration or shaking in the steering wheel when braking. It may mean brake service is needed immediately. ## Customer Reviews ### ⭐⭐⭐⭐⭐ OEM for a good price *by on Reviewed in the United States January 23, 2025* Great OEM replacement, fits a 2000 Silverado perfectly. Good quality grommet that fits without trouble and seals well. ### ⭐⭐⭐⭐⭐ A little different than OEM, but fits on OEM brake booster. - 2008 Impala LT *by on Reviewed in the United States January 23, 2020* I original bought this check valve kit to remedy a suspected vacuum leak in the brake booster area of my 2008 Impala LT. I was noticing an audible hissing noise when pressing the brake as well as noticeably reduced braking power. That being said, this item did not fix my issue but it's worth checking out before other parts since it's very affordable.The fix for my vacuum leak came from the plastic/rubber seal within the brake booster itself which is not a part you can purchase by itself. You have to purchase an entire new brake booster or pull the part from a brake booster on a similar model year Impala from an auto salvage yard.This item is slightly bigger than the OEM check valve and a different color (slightly off white/grey). See pictures for packaging and side-by-side comparison of OEM vs this AC Delco check valve.I've attached bonus pics of the original brake booster seal that failed and caused the brake booster to malfunction and the intact one I pulled from a salvaged Impala. Hope this helps! ### ⭐⭐⭐⭐⭐ Quality product *by on Reviewed in the United States April 30, 2025* Works like a champ.
