Front brake pulsations

My 99 Grand Cherokee is getting front brake pulsations and has never had the brake caliper upgrade from Teves to Akebone. I've read that changing over to the new brake caliper doesn't always permanently solve the problem. Has anyone on this forum come up with a way to permanently eliminate the pulsations without changing the calipers or is there really no way around it?

A couple years ago, I switched to drilled rotors..... OEM are crap. I still have calipers that came on my 2000 WJ, but no more pulsations.

I had the calipers switched. Solved my problem for a while and then it came back. Replaced new pads and rotors and the problem went away. My problem were the rotors the second time.

Sounds like a warped rotor. Did you put on ceramic brake pads when you changed them? thos create a lot of heat and will tend to warp rotors faster. Drilled or vented rotors will help with this.

I did put ceramic pads on it to reduce the amount of brake dust on the wheels. Where do I go to get a good set of drilled or vented rotors?

PM Kolak on here. He can get you a great deal on Stillen pads and Rotors. For about the same price as the Duracrap you can get from autozone.

Do the caliper swap. I spent $300 on new rotors/pads and they ended up warping a few months later.

Jeep - Brembo - AutoCarParts.com

Here is a starting point. They are expensive, but top quality from what I know of them.

Thanks guys! If I do decide to switch over to the new calipers, what is the best/cheapest way to go about getting them?

^--- What they all said...

And, I'll go ahead and state the obvious: Over-torqued lug nuts can warp rotors. Period. Get a torque wrench if you don't already have one and torque them anywhere from 80 to 110 ft.lbs., I just always go with 100. "Tight enough" and "as tight as I can get 'em" are NOT acceptable. Same guys that abide by such are usual suspects when their brakes (also suspension and steering to a lesser degree) give 'em fits. Trust me, I know what I'm talking about on this. It's not simply a matter of being "torque anal," as many have suggested; and I realize that you may well be doing everything correctly but this for the sake of other readers. My 2 cents, FWIW.
