From my post 2 years ago:<BR>....I have also spent a lot of time and effort analyzing and trying to fix this problem. This is my experience:<BR>I started by adjusting the parking brake cable. This worked for a couple of days. I then replaced the clips which hold the pads to the piston. This worked for a couple of weeks. Besides these failures I've chamfered the pads, resurfaced the rotors, installed anti-rattle shims, applied brake lube, and even resorted to applying high temp RTV behind the pads. My pistons are free, my brake cables are free and well lubed, my fluid is clean. Still no lasting fix.<BR>To add to the confusion, I do not have this problem with my '90 even though I used the same pads (Raybestos).<BR>We have a lot of talent contributing to this Forum and most testify to having success after using OEM pads, though I cannot determine the reason for this.<BR>....I finally got to my brakes. Inside the box of my new OEM pads was this note: "When installing these new shoes and linings on 1986 and early 1987 vehicles, you should discard the bracket insulator shims that were installed between each end of the shoe bracket. These new design shoes are longer than the original shoes and do not require the bracket insulator shims."<BR>I've replaced my pads. What a relief it is to get rid of that noise. The brakes sound solid. Apparently this issue includes 1989.
