I went out and bought Raybestos slotted rotors and ceramic pads for the front brakes on my 93. What a difference...no shutter when braking, no more dust, no squeak. At first they seemed not to brake as good but I was taking it easy. I broke them in by doing a series of hard to soft braking and used the e-brake to hold the jeep at a stop light so the brakes could cool. After a few days of doing that I had an emergency and had to rush my grand son to the hospital with an anzyema attack. I had the flashers on and was doing some serious high speed driving and hard!!! Braking. We got there in time and after I settled down I remembered the new brakes. No damage and I'll tell ya when you really come down hard they got better as they got used harder. Like night and day.
I wanted to get slotted and drilled but because the rotors are not cast they only recommended slotted. They work great. I'll be going to Yosemite next week and will give them a great test coming out of the mountains.
