Brake Pad Shifting

My brake pads seem to shift excessively when changing directions. For instance, after braking while in a forward motion, I reverse and hit the brakes. I can feel the pads shifting in their seats so hard it vibrates throughout the whole car. It's pretty embarrassing for a 50k car.

Anyhow, I've brought it to the dealer for this a number of times and they can't seem to get it right. I know the first bunch of times I complained, they tried using some kind of adhesive to get the pads to stay which worked for a short time, but eventually resulting in the same problem (as expected).

At my last visit, they changed all brake pads. This seemed to solve the problem but again, same issue. Seems to be coming from the rear.

Does anyone know what is going on, what the permanent fix is, or have any insight? I wouldn't believe it if this was "within spec" as there's something obviously wrong.

OEM pads? Are the spring clips installed?

OEM pads, not sure about the spring clips. I'll have to check the next time I have the wheels off. Dealer installed the pads so I gave them the benefit of the doubt.

I would hope they did as well, but could be worth a look. And OEM pads still have the clip that fits in the caliper, so it can't be that either. Is it possible that its something else besides the pads, like a loose diff support bolt or sway bar link?

Unlikely

You're attributing your car's symptoms to a rare phenomenon. I would look elsewhere in the suspension for something loose and shifting as loads go from deceleration in one direction to the other.

i would look for bad bushings in the wishbone arrangement. On an e30 and e36 the control arm bushings or ball joints could make this happen. I know an e90 doesn't have the same arrangement but a bad bushing or ball joint on the wishbones could cause that.

Pads make the wheel vibrate a little. The movement is pads is so small I doubt it can be felt like that. Look for bad bushings or ball joints.
