![]() I think the alignment may be important, if they are not parallel, seems that would impart vibration/noise till the clamping pressure is enough to make everything rigid. Either that or mount is not rigid enough as was discussed , You've eliminated pretty much everything else

![]() Not sure if you've solved this problem yet but I had a similar issue on the rear of my car. It turned out the shim that goes under the pins was dragging the rotor itself. I'm using OEM rotors. I ended up just grinding the OD of the rotor down a touch until it was no longer a problem.
I do have some squealing from the front now, but only when everything is super hot and only at really low speeds. Normally its fine. I'm on stoptech sport pads with no backing shims.

![]() Sorry man didn't read your posts. My current squealing situation sounds similar to what you have, but only under 5 mph or so. I really don't care about it much at that point, its only when hot. I'm not even running shims in the front.
The first issue was on the rear. I could see witness marks on the outside of the rotor where the clip that holds the pads down was dragging. This was causing a squealing noise that went away when I got on the brakes. Again this was only on the rears though. |

![]() Resurrecting from the dead. This is the part you want to make the squeal (really more like the whole car resonating and sounding like a foghorn) go away: 30748514
https://www.fcpeuro.com/products/vol...0-v70-30748514 Ignore the product name on the URL. |

![]() That's right. You just have to grind a couple reliefs for the bolts.

Edit: tempted to order them myself but not sure the bolt pattern is the same for the caddy calipers. |

![]() Found some pictures by searching the part number. So yeah, damper in between bolt and caliper/hub

![]() I don't know anything about a shim that goes between the pad and the pistons on these R calipers. There is no Volvo bulletin for that, the bulletin is for the early cars that didn't have the mass dampers/weights/anti-vibration blocks you see mentioned above.
We had some intermittent issues with this sort of noise complaint even on a stock S60R that had the mass dampers installed. We installed Akebono Ceramic pads and Textar OE replacement rotors then the car developed brake noise(coming from worn Volvo pads and rotors). We switched to Volvo pads but it still made the noise. Then we swapped the Textar rotors out for Brembo OE replacements and the noise went away. Your experience may vary, and to those who have said that shims behind the pads are needed, are you making this up based on your thoughts with another application, or do you have a part number for something Volvo sold to help this situation?

I just pulled up my VIDA and confirmed there is no shim listed in the brake system for the R calipers. Just those vibration dampers on the back of the caliper. Jordan |
