Lousy stock brakes

I have a question concerning the brakes, on my 04 GTO. The question is has anyone had problems with brake squeal,on there cars. My GTO has 6,300 miles on it. I had all 4 roters resurfaced, wich only temporaly stopped the noise. I now have the noise back as loud as ever.I am not sure if new pads will stop the noise. My dealer has not been too much help. Any advise would be greatly appreciated.

I upgraded my brakes the first week with AP's kit which is the same as the HSV GTO optional. They're 14.25 front with 6 piston calipers and 13" rears with 4 piston calipers. Expensive yes, worth it... OH YEA! There are a number of cheaper kits out, Wilwood, Baer and Stoptech all have avail.

I have a 1998 GTP with a similar problem.

I changed to ceramic Raybestos silent pads and haven't heard a peep.

I'm not sure if these are harder on the rotors (a distinct possibility), but they're absolutely silent.

The '04's brakes do, indeed, suck.

I put PowerSlots all around, with Hawk Pads up front. It still doesn't stop as deciseivly as I would like, but the car does slow and stop with way more linearity and confidence than stock. I cooked a rotor or two at around 15k miles, so I decided to upgrade.

Not as great a solution as bigger rotors and more calipers, obviously, but it only cost ~$450 or so.

Cough... Ahemm.. I better get that Valentine1 first to obtain speeds that justify this kind of expenditure...

What size wheel do the AP calipers require ?

I run 19's but 18's fit they said. Harrop has a kit with 15" fronts and 8 pot calipers!

The Stoptech kit with 13's is $1995, with 14's is $2595. Here's the Wilwood and Baer kits at TByrne.com http://www.ls1gtoperformance.com/gtointro.html

brake squeal is usually caused by vibration in the pads against the calipers. anti-squeal inserts or adhesive you apply to the bakc of the pads and let cure should minimze and or eliminate the squeal. If you don't have C5 Corvette brake pads installed, I would also suggest doing that to improve braking - they have the same backing as the GTOs but close to twice the surface area. Then bleed and flush the brake system with Valvoline Synthetic brake fluid. GTOs are notorious for having air bubbles trapped in the brake lines. Took me two bleeds/flushes to get them out.

I tryed the anti squeal spray, it did not work. I did order ceramic pads for both front and rear. I hope they will help. I will keep everyone posted when I put them on. Thanks everbody.
