After 5 sets of rotors I am vowing never to use raybestos again. I have gotten 4 sets on warranty in two years, they all warped. I have tried all the tricks. Cleaning the hubs, torqing to 80 then 100. re torqing each oil change. The last set had a shutter right out of the box. I have had it with the raybestos brand.

This time I am going with NAPA Ceramic pads and Wearever rotors from advance. Hopefully I will have better luck.

Even the raybestos pads I had were junk. They were the Ceramics, and the material was cracking off the backing plate. Im just really disapointed in them.

Just wanted to vent.

PS-This time I tried a 'Bedding' procedure I have heard autocross and racers using to break in new rotors and pads. If any one is interested I can post it.

Jay, the pads are not your problem. The rotors are.

Are AC Delco DuraStop rotors the same as Raybestos rotors?

I have never had good luck with Raybestos products but that may just be me.

I've been running the Raybestos pads for almost 3 years now. They work great.

Never had problems with Raybestos. Like Willwren said, bad quality rotors will destroy any brand of brake pads.

That may be true about the pads, but look at his post. He said he used 5 sets of Raybestos Rotors and had problems. Are you running Raybestos rotors too?

Never heard of Raybestos rotors.

But their ceramic pads are the best. Especially with a good-quality rotor.

FYI, any 'run of the mill' rotor will fall victim to ceramic pads on the 87-99 generations. The larger rotors on the 2000 and newer hold up better.

When I replaced rotors and calipers on 98 there were two grades of Raybestos rotor offered at Pepboys. I bought the more expensive one. The other was lighter and matched the original GMs in mass. The more metal, the more heat it absorbs to reach a certain temperature. Better for braking hard.

Raybestos makes two type of rotors; a standard and a heavy duty. No, I do not have Raybestos rotors; I have SP rotors and they have been cryogenically treated (frozen) for longer life. In the past, I have used the Raybestos heavy duty rotor and did not experienced any problems.

I recommend that you also take a look at the caliper slider and make sure that they move freely, and also the caliper piston movement too.
