I have front discs and they squeak like mad when braking - I mean really loud.

The pads are in good condition. In fact they've barely been used and the car was garaged for about 2 1/2 years (Delphi pads purchased 4 years ago), which makes me think that maybe they were a  duff set?

I've removed them, cleaned the surface back with a wire cup brush and copper greased the rear of them, plus the clips. but non of this has helped.

 

Any ideas?

 

Thanks

 

Luke

I had exactly the same issue with an 8.5" disk brake kit I bought. Tried everything same as you.

I found some anti squeal shims for that brake system from one of the parts suppliers in the UK and fitted them and they have been perfect ever since.

They even gave me better pedal feel and travel (maybe there was some air in the caliper that got pushed out when I pushed the piston back to fit the shim).

Don't know what size brakes you have but hope this helps.

Can provide more information i.e. part numbers etc if necessary.

Regards,

Mat.

If your car latest 8.4 inch standard discs and calipers then fit anti squeal shims.

picking shims up today. 

do you use grease or lube?

If so, then both sides of the shim?

Ideally Mintex Ceratec, but a light smear of copper will help.  Just avoid getting it on the friction faces at all cost.

Apply to both sides of the shim?

Shims fitted this afternoon. Took it out for a test drive and silence  :D  :D  :D  :D  :D  :D

 

It was unbearable and now the smile is back on my face....short lived for a mini owner though.

 

Thanks again guys.

Good to know its fixed and what fixed it.

If you ever need any advice no matter how silly the question sounds you're in the right place.

I've been here since 2008/9 and even I'm still learning

Glad it's fixed.
I use thin smear of cooper slip both sides of brake shims.

Be aware that when the pads are re-bedded the noise could return. That's a real pain.
If it does, remove the shims and run without for about 500 miles then refit the shims.

ok, so that didn't last long. Came back after about 6 drives  :(

is it worth replacing the pads to resolve this?
