Do I need to replace the rotors?
At 83K miles there is ~3mm left on the factory front brake pads on my wife's 05 GX470. The truck brakes smoothly, that is, there is no pulsation on the brake pedal when the brakes are applied. I am planning to replace the front and rear brake pads this coming weekend.
Is it OK to just replace the pads using the existing rotors? If there was pulsation I would definitely replace the rotors.

Measure for thickness if they are within the acceptable tolerances and there are no other signs of physical deformity, old pads wore evenly, no pulsing etc no need to resurface or replace the rotors. Just make sure to bed the new pads in properly, which will also help to remove any glazing on the rotor surface.

well that may be what the posts say, i replaced front pads at 25, 50, 75 and 107K, the rotors were resurfaced the first three times and just replaced at 107,000. I had no problem the first three times, no vibration at high speed braking. so...your call, rotors aren't that much anyhow.

OEM rotors can be purchased from a Toyota dealer for considerably less, they are the same rotor found on the Toyota 4-Runner V-8. Also try Sewell http://www.sewellparts.com/
I have not had favorable experiences with aftermarket rotors to include Brembo blanks and PowerSlot Cryo rotors.

No pulsation = no rotor warping... Measure for thickness if they are within the acceptable tolerances and there are no other signs of physical deformity, old pads wore evenly, no pulsing etc no need to resurface or replace the rotors. Just make sure to bed the new pads in properly, which will also help to remove any glazing on the rotor surface.
You'll be surprised how good the brakes are on your GX with proper bedding the new pads.

Or just go to Autozone. Their parts have lifetime warranty. If the rotors warp, you bring them back and they will replace them. Make sure you save your receipt.

Replaced the brakes during the weekend. Found a frozen piston on the driver sider front caliper. Used Autozone Cmax pads (front + rear) and Autozone caliper. The work of replacing the pads + caliper if very straight forward. After the pads were installed, I followed the process for bedding the pads. Everything works very nice. Braking is good + no pulsation or pulling.

I used the Cmax pads with drilled/slotted rotors. They seem much better however not sure if I need to "bed" them in. If Im not mistaking I believe its like hard stops from 60mph-5mph 6-8 times twice....Does this sound about right? any mechanics out there in favor or opposed to the "bed" in process. Ive never done this before in the past and never had a problem. Also with drilled/slotted is it required? Sorry- not trying to hijack the thread just curious.
