Squealing Brakes Help

[thescamper]

SWMBO has an aging Reno Scenic which has had squealing brakes for a while, at the recent MOT it got an advisory that the front discs where thin and that the pads were about 85% gone.

I have,
fitted new mintex pads and discs
copper slipped the back of the pads
copper slipped the shims
cleaned and greased the caliper sliders,
rubber greased the slider seals and caliper piston seals

And the bloody things still squeal, I have run out of ideas of how to stop them has the pistonheads collective got any ideas?

Thanks in anticipation?

Are you sure it's not the rear brakes?

[thescamper]

Im convinced its the fronts, however my plan is to change the rears next month anyway.

Try applying the handbrake lightly while moving to see if you get the noise.

Chamfer the leading edge of the friction material.

The pads came with this already done.

If my experience is anything to go by, I have highlighted your issue. I was seriously unimpressed by mintex pads, squeaked for the first 10k miles, stopped squeaking for about 5k miles then squeaked for the remaining 10k miles I had the car.

Have you done a proper bedding in on the disks and pads? I always thought it was inadvisable to replace both at the same time.

The big no no is to fit new discs onto old pads. New pads on old or new discs is fine.
