I am having terrrible troublewith the front rotors on my 1999 Tahoe.
Does anyone have any suggestions? I punt new rotors on and get about 5000 miles before vibration starts. I have rotors turned and 5000 miles later vibration is back. Any suggestion on a good aftermarket rotor that will not warp?

make sure your front calipers are not binding and that your caliper slides are lubed also make sure your rear brakes are adjusted right if they are out of adjustment your front brakes will do alot more braking

I have the same problem. Everytime I change the pads I do a complete overhaul ( meaning I get the rotors turned and lube all sliders)

Rotor warpage is pretty common on these heavy vehicles. Unfortunately, turning the rotors can compound the problem. IMHO, there are two things that you can do to avoid/delay the warpage. 1) NEVER tighten the front lugs with an air wrench - not even with torque bars. Instead use a torque wrench and cross-torque each wheel in three, progressively tighter sequences. For example: with aluminum wheels cross-torque first at 70lbs, then 100lbs, then 140lbs. This is very important! 2) take some of the burden off the front brakes by periodically manually adjusting your rear brakes. If you don't have an access hole in your brake backing plate, you may have to drill a recessed slot that is there for adjustment purposes. You can plug the drilled slot with plugs sold in the HELP product section of your local auto parts store.

Unfortunately, you may find yourself buying some more rotors before you can get relief by implementing the two above steps. Advance Auto sells WEAREVER rotors at a good price, and they have a one-year warranty - to include warpage. If you don't mind spending a lot of money, PRAISE makes a product that is hailed as one of the toughest rotors.

You could consider using cross-drilled and slotted rotors. They aid with reducing warping & give a longer rotor life.The drilled holes provide an exit route for gas and dust, resulting in better heat dissapation.With cooler running rotors there is less brake fade. The slotting provides relief from the gas produced from the pads under extreme conditions.This gas creates a cushion between the pad and the brake rotor.The slots and the holes clear away gas restoring full contact and reducing heat.
