Why do brakes need to be replaced in the first place?

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.

What’s the squealing sound I hear when braking?

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.

What if it’s more of a grinding sound?

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.

What about vibrations or shaking in the steering wheel?

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.

Why do the brakes seem to pulsate when stopping?

It may be due to poor-quality brake pads, warped rotors or unevenly worn tires. Have the pulsation diagnosed as soon as possible to avoid the possibility of greater brake system wear or damage.

Exact match for my’18 GMC Sierra

Replaced the front rotors on my truck, driver side was wearing against the pad inconsistently, thought it was just the driver side but bought two just in case and same issue on passenger side as well. Now new rotors and pads and good stopping power and they look good too. No warpage and both brand new. One gave me hesitation since the box wasn’t in the best shape, they even wrapped it in bubble wrap. But upon opening, I was relieved to see it brand new in a sealed bag just like the first one. Great price and fast delivery.

Initial impressions very good.

Great price on Amazon...Easy to fit and correct for vehicle. Cannot comment on durability as I have just fitted them and broke them in. Matched with pair of raybestos pads, no noises and improvement on previous brakes.

Another Superb AcDelco Part

Beautiful rotor that fit perfectly which eliminated the noise from my truck’s front brakes. The rotor appears to be well made and extremely smooth with easy installation.
