## Questions & Answers

**Q: Why do brakes need to be replaced in the first place?**
A: Friction material on the brake pads or shoes rubs against rotors or drums to slow the vehicle. 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.
