New front brake pads and rattles

This is a FYI for those who develop a metalic "clack" soon after replacing front rotors. For verification, push lightly on the brake pedal with your left foot while going over expansion points or rough asphault. If the noise goes away, the inside pad is loose.

The inside pad has 3 spring prongs that hold the pad against the caliper piston. If the pad is loose, the only noise you will hear is a 'clack' at every bump. Sounds like a loose heat shield or suspension member.

I just took mine off, expanded the spring clips just slightly (too much and it will not slide), put brake grease on the spring tips where they contact the piston, and the 'clack' is gone.

This also happened to my wife's A4 several years ago.

    I'm having a mysterious clack that I thought might be something loose with brakes. It's not over every bump, but in starting out, or going in reverse, and is very infrequent. One clack and then not much else. Also is the front outer pad supposed to appear to contact the rotor when parked? I was surprised to notice this and need a little more info (and check other wheels) before taking things apart. Great post, Thanks!

      Parking the car means you have a foot on the brake when the engine is shut off, the pad will not move much at all. You will want to check the slides and make sure they are free and clean ( a little brake grease won't hurt).
