Rattling Noise From Wheel Area

[GatorInSC]

I have a loud rattling noise that comes from my left rear wheel area when I go over bumps or rough areas in the road. The rougher the road the louder the rattle, but mysteriously the rattle disappears if I have the brakes pressed even slightly. Does anyone have any speculation as to what this might be? I can't imagine what would cause it not to happen if the brakes are applied. Thanks in advance! I have a 1994 325ic.

I have a '97 328i, and im having a similar rattle. But this is only when i het bumps. I think it could by the old shooks, but i friend with a 94 318ic said it could be the strut mount? Does anyone know?

ok your problem is the caliper that hold the brake pads. Normally they should fit really thight and not move. I used to have the same problem. It is nothing critical, don't worry, nothing will fall out or anything. The noise is very annoying though i must admit.

If you wanna buy new calipers, it can turn out to be quite expensive. Over here in england they are 150 pounds a piece, so about 600 bux for both sides.

What i suggest you do is take out the brake pads. You will see some thin metal brackes on theonside that go into a hole in the caliper. Just make those a bit wider by hand and put some heat resistant grease around the corners.

That is what i did and everything is fine now there is no rattling at all anymore.

Another thing you can do, but i do not reccomend this one is just to put a welding spot on both sides of the caliper where the pads are suppose to lean on, it will create tha half a millimeter you need to stop the rattle.
Hope this helps
