Default The old squeaky noise is back!

I have a small squeak happening in the front left wheel, I have taken the pads off and cuffed them, no problems after that then it returns, it sounds like a budgie is stuck in the front wheel!
As soon as I put the brakes on the noise stops, wheel bearing? discs? pads?
All good Dave NZ

That sure sounds like the break pads are worn out. GM has a squealer built into the brake pads called a wear indicator. When the pads are too worn they squeal until you apply the brakes. Let off and they squeal again. There's a small "finger" that rides on the edge of the rotor that squeals and is flexed out of the way when you step on the brakes. Here's a link to a page showing it:

Also lower grade pads tend to do it as well... sometimes when mine are hot they will squeal a little....comes and goes

Hi Guys, thanks for your replies, I forgot to say the pads are new "hi performance" ones but I may change these to see if the budgie goes away, question should I change just one side or both?

I had that problem for years, front and back. I tried everything but the squeak always came back. So a few months ago I changed all four calipers to O ring system and that did the trick.

Some of the venders sell strips that go on the metal backing plate of the pads. Sometime some high temp grease or copper lube will work on the edges of the back plate where it contacts the caliper. The sound comes from the metal to metal contact from the pad back plate to the caliper vibrating together.

Worked at a dealership in the 70's and we use to put a couple layers of Duct tape on the back of the pads to stop the squealing..seemed to work well in the early disc brake days
