squeaky (new) brakes

[rivarama]

I bought my GT last week, and the brakes have been squeaking pretty much from day 1.
The car was fitted w new breaks and pads on the front and the back only had 5% wear according to the inspection.

At the beginning I thought it was due to the newness, but after 300miles, I don't think it's going away.

The squeaking doesn't happen immediately when I brake, but only from the speed of 5-6mph to stand still. So in traffic, you can imagine the symphony...

I really cant tell if its the front or the back tbh. Interestingly the noise doesn't appear right away when the car is 'cold'... It would start squeaking after the 3rd/4th stopping down.

Not sure what's wrong w it. I don't really feel like changing new pads already, but this noise is going to drive me nuts... Any thoughts?

Thanks

Be interested to know what it is. My Merc does exactly the same!

Congrats on the new car Geoff btw.

Try putting coppaslip on the BACK of the brake pads. Squeaking brakes are indicative of pads vibrating in the calipers.

Jump on them from high speed if they are new and also check they are not binding or as Martin says vibrating.

I slammed the breaks a few times yesterday, and the ABS definitely was activated - so that should have sorted it out... But that noise still persists.

I don't feel that they are particularly vibrating - or at least nothing that bad that I can sense it.

Is coppaslip something that can be applied without removing the wheels? and is it a DIY job (read, retarded person that has 2 left hands and never touched anything mechanical in his life)I do it myself?

If indeed the pads were vibrating in the calipers, wouldn't that also happen at higher speeds than 4-5mph? How can this be sorted?

I'm going for a lack of copper grease on mine when the pads were changed. As it only squeaks at low speeds.
I'll get them to put some on when it's serviced next.

Erm nope. Wheels off, pads out. Not difficult, but make sure you put the copperslip on the right side of the pad......

and check the pads are the right way around (it has been done before)...

Don't use copper slip, it reacts with the rubber dust seals and knackers them.

Our 3200 calipers need rebuilding due to copper slip use.

Top tip right there!
