Squeaky brakes!

[Gazza450]

I think this may have been covered before on here but the brakes on my 2007 V8V have started to squeal on light braking, just as I come to a halt. I have checked out pad ware and they all have plenty of life in them. I have replaced the rear pads recently with Pagids and I have also given them a proper roasting but still they have this rather embarrassing squeak as I come to a halt. Before I remove all pads and apply copper ease to the backs, does anybody out there have any experience with this problem and any ideas about how to stop it?

Personally I'd try a few firm braking episodes from a reasonable speed before dismantling things. May be something simple like dust stuck.

Did you use anti-squeal or brake grease during installation? Did you use shims? Anti-squeal/brake grease and shims? None of the above?

Use ceratec not copper grease

Give your handbrake a pull when driving slowly. This wil fix it for a while.

Could be the handbrake pads dragging so give that a pull as above, get it checked next service

Could be the pads have glazed over with light use/stood a while so try doing the bedding in procedure again.

OE pads are Pagid RS 4-2-2 (unless they have changed)

Brake squeal has been the subject of PhD study, and is highly complex. Basically you have a resonance in the audible range, and you need to change something. Manufacturers will look at disc material/grade, surface finish and pad material. Damping, by putting a viscous high temp grease on the pad/caliper contact faces may work, or may work for a while. De-glazing may work. Removing a step at the disc edge may work. If these fail, I would try a different pad material - it's the easiest practical cure (if the material has sufficiently different characteristics).

Thanks guys, lots of good suggestions there to work through. I'll come back to you if I can identify a clear winner that cures the issue.
