My 96 has some annoying rattles... As I drive and hit bumps there's a metal on metal clanking sound. When the brake pedal is applied the rattle stops. I have basic knowledge about brakes and have always done my own pads/rotors etc. This noise started many thousands of miles after my last brake change. My guess is the caliper has issues?? I imagine someone here has had a similar issue. Thanks, Max

Can you isolate it to front or rear?

In front, the inner pad anti-rattle clip (mounts on the inner pad, then slips inside the stock caliper piston). One or both (one per side) may be missing.

If the front caliper bushings are hardened and dry, it could result in the ability of the caliper to move around and make metal-to-metal contact on the caliper bolts--aka "rattle".

In rear, if the pad anti-rattle springs are not positioned correctly, and/or the H-clip for the springs to bear against is missing (mounts inside the "window" on the caliper body) it would be entirely possible to have a rear pad rattling.
