Good afternoon and merry X-mas to all bricksters. Hoping to get some input on rear brakes. Recently I did a complete rear brake job on a friend's '92 245. This included new e-brake hardware and shoes, new discs, pads, hardware, the works. E-brake properly adjusted. Every once in awhile she gets this low, moaning sound just before stopping. Thinking this was e-brake shoe drag, we have readjusted that, but to no avail. Could this be something else? A source has suggested that we need the "attenuator kit", which apparently eliminates vibration in calipers, or some such thing. I had never heard of such a thing, but a few days ago I stumbled across a 245 with large, triangular, rubber bumpers bolted in place back there pointing toward the ground. Does anyone have any information on this issue/part?

Thx,

Dave
