1999 Jeep Grand Cherokee 4.7 V8 Brake question

I would like to update / replace the brakes a 1999 Jeep Grand Cherokee Limited 4.7l V8.

It is drive pretty hard and am looking for ceramic pads, and slotted and drilled rotors, etc. Basically best parts possible for high speed breaking with limited fade and good heat distro. this might include new calipers, etc. All suggestions welcome on good parts to get that will last and perform well under hard conditions.

As I haven't done too much research I was hoping someone else might have tried this. The vehicle is sometimes used for high speed pursuit and after warping one set of rotors I think I need more than OEM parts.

Thank you very much. Are you telling us what you want to do or do you have a question?

I do not see where your question is? Are you the good guy or bad guy??

AutoZone has a just what you need. The rotors are $210 each and ceramic pads around $40. You're putting that much money into it, I would change the wheel bearing assy also. Consider wheels that divert more air to the brakes.

Maybe a brush guard and keep that bullet in your pocket! kautyy wrote:Are you telling us what you want to do or do you have a question?

hehe yea sorry.

What pads and rotors do you guys recommend? I don't know if I would use ceramics on a high speed pursuit vehicle. As for cross drilled rotors I personally believe that blanks are better because you have more surface area for the pad and cross drilling the rotor weakens the rotor. They are more for looks and weight reduction. I know that Porsche and Ferrari use them, but they are bigger than 17 inches and usually backed up with 4 piston calipers and external venting. Plus the rotors are designed for cross drilling and not some cheap Autozone blanks that were cross drilled with someone's electric drill. You could call your local highway patrol maintenance office and ask them what make of pads they use on their vehicles. Honestly I don't think that a Jeep Cherokee is an ideal highway pursuit vehicle, so be careful while cornering at 60mph+. I was going to mention that.

The whole idea is to keep the brakes cooler, which they do. Also the dust is light and not as noticeable. Performance about the same. Longevity is greater. But I seen metallic pads with better warranties. I put D&S rotors on my 03 Honda Accord. They don't make much difference, but they made lots of noise! I had a great hum in relation to speed when slowing for a stop. They were cheap, from EBay, and they exchanged the front pair for a new pair, but there is still "some" noise. Not as noticable now, but still there. Look great on all fours, but I wouldn't do it again.

I was thinking yesterday, of maybe getting the originals resurfaced and reinstalling them someday. Nice venture, but maybe write off the new rotors as a trial & error.

Anybody want to comment on the "noise" thing with D&S rotors? Is this normal?
