I need a Brake
I do not have the part# . but you want to use a pad that is cerro-metallic in composition. Be sure and check to see that the disc is more than minimum thickness for safety. I always install new pads and use brake lube at any point where there is metal to metal contact. Don't overlube but the lube will assure you don't have to endure noise. The squealing noise is actually vibration, but we hear it as a squeal. While you are there, you might see how long it has been since the wheel bearings were cleaned, inspected and repacked. Be sure to replace the grease seal if you repack the bearings. If you are not familiar with all this a trip to the library will give you a look at the Chev service manual which details all you need. If they don't have the Chev manual, they will have several books on automotive chassis and brakes. Put your rig up on a heavy duty set of jack stands for safety. Hope this helps.
