'99 SL2 and Front Rotors

Check two things - 1) Front wheel bearing is going slowly and leaking grease out that is getting on the rotor. 2) Rear brakes not self-adjusting, causing over working of front brakes.

Or the rotors that were used were inferior to begin with. Better to pay a little more up front than to have to go thru this every 10k on cheap Chinese rotors....

When I first went to Vespia's they wanted to install Saturn OEM rotors. I told them I did not want that and they supposedly installed Raybestos.

Maybe I need slotted rotors to dissipate the heat?

So the vibration was only felt while braking, correct?

My experience has been that the wheel nuts have to be torqued to factory spec (it's in your manual - my 97 with factory alloys runs 103 ft. lbs.). And then 30-50 miles you do it again (my fronts usually back off a little).

Turning or cutting rotors is common, however in theory you are removing mass and they will heat fast (potentially fading faster too). I'm not sure running to the store and back you'd notice this as long as rotor thickness was kept within legal spec.

From what I've read, the guys here have had pretty good luck with all rotors, from cheap Chinese rotors to more expensive ones, even sport rotors (drilled, slotted or both).

I'd bet you a cyber nickel it's wheel nut torque.

I've run factory rotors, Stillen's and Powerslot's.

I second what Jonnie said on both counts:

I'll let you know on Fri. The appt is for thursday and I get the EBC pads on Wed.

Thanks for the help! Bob

I went through a problem with warpped rotors, replaced them with ones from AutoZone (possibly made by Brembo but not that name) and EBC pads. I started getting vibration again after a tire change I thought here we go again. Someone posted a link which discussed material build up on the rotors as a possible caus (less than 0.001 inch). At the next oil change I rubbed the surfaces of the disk with 80 grit sandpaper in a swirl pattern- brake vibration was much reduced di the other side - it was gone! Give it a try YMMV. EBC pads are really good for my driving style, hard braking into ocrners as in autocross.

I have EBC's GreenStuff pads currently - nice balance of initial bite and hot braking (not track stuff)...

With my '99 I had aftermarket ones installed by the dealer of all things. I can't remember the brand, but the dealer offered two different brands with differing prices. Still work great now the car has 80k on it. Just make sure your wheels, whether steel or alloy are properly torqued.
