Raybestos = junk??? ( Cracked pads and cracked rotors)

All my brake problems started when I installed Raybestos Quiet Stop pads a year ago. Since then I've gone thru 3 rotor pairs 1 rotor turning in a mere 20kmi. In each case vibration sets in a few thousand miles after the brake job.

Last night I removed my Raybestos Quiet Stop pads w/20kmi on them and my Raybestos PG Plus rotors w/5kmi on them. Both the rotors and pads had hairline cracks!! The pads cracks went all the way thru and the rotors looked like shallow surface cracks/casting defects. The rotors also showed some spots that showed discloration. (about 8-10 spots the size of a dime around the circumference of the rotor.)

I torque my wheels with precision and I was careful to break in/season these new rotors. (the latest rotor set is PG Plus and they're supposed to be premium quality - at least the price was).

Fortunately Schucks took back everything and gave me new pads and rotors - no charge.

I'm reluctant to use the new replacement Quiet Stops since all my problems starting with these pads. I'm planning on tossing them and trying Performance Friction pads or OEM.

Are Raybestos products junk or an I plagued?? Any other suggestions??

My car is a Pontiac GTP but it's a daily driver.

I think that you should get to bottom of this fast - sound to me like you've either got a bent caliper or they are sticking - most of the
Raybestos line will go to 400 degrees without a problem, but your disoloration says that you're getting hotter than that. If you drive the car hard, then a brake upgrade is REQUIRED for this car - I run
Baers on a couple of cars - but if you don't, then you have a problem that will get you into big trouble if you don't solve it.

The hairline cracks say that something is out of whack in the system - maybe studs are not done right, but I'd suspect either a bent or misaligned caliper (maybe two) from your description. If you need higher temp pads, go get some Mintex - I love them - can cook my brakes without trouble ( I also run some ATE super blue or gold fluid with high boiling point). DOT4 fluid can go up to about 550 (Wilwood), but you may be running hotter than that with the disolorations. The other thing that you might need is better rotors - I think that yours are designed for the standard Grand Prix, or a proportioning valve (check
Wilwood again).

I'd start from scratch, and get a dial indicator on the rotors, and then check the caliper alignment, and then check the calipers themselves.
Then take off the front wheels, have someone put the brakes on, and watch the calipers for flex and retraction. Something is definitely amis here, and Raybestos makes good pads. If there is nothing showing, then I'd change rotor type, and pad type.

By the way, tell me where you drive, I'll stay away for a while.
Youo've got a brake failure wating to happen

Raybestos is pretty much the standard for brake parts in the U.S.
Extremely quality-conscious, a division of Dana, lots of R

Wheel bearing causing the rotor to track untrue? You said pads and rotors as in more than one. Are you a 2 footed driver ?

Raybestos brake parts are good quality. Used them many time without any problems. It's one of the rare few good quality parts that Pep
Boys sells.
