Upgraded Brake Rotors?

[that_macheguy]

My GTPE has almost 13k miles and the front rotors are warped to hell. I always used 1 pedal driving. My one pedal stopped working due to a faulty wheel speed sensor so I had to use the regular brakes. The wheel pulses so bad when braking. Is there any upgraded rotors from anywhere yet for these?

Did you do a panic stop or a high speed stop? I'd be very surprised if the rotors warped under normal use. One thing that can happen that feels like warped rotors is material transfer. In that case, you have to get them pretty hot, then come to a complete stop with your foot on the brake. Material can transfer from the pad to the rotor, and it creates a thick spot.

The pulsing is from non use of the friction brakes. The stock rotors are plenty good. Yours are just contaminated. You’ll have to use the friction brakes regularly to clean them off and keep clean.

Bingo.

That would all be covered under warranty. Get the sensor fixed and ask them to put a run out gauge on your rotors. I bet you will find they are straight and true. And if not, they will be replaced as well.

I warped rotors on a car once. Wasn’t from any of the above.

It was from washing the car when the brakes were hot.

That reminds me of when some sanctioning bodies allowed liquid cooling in addition to air. As with everything else, it got expensive so they had to save us from ourselves and make it illegal.

I have only warped a rotor on a 1/2-ton 4x4. Too much load, too much speed, hilly and curvy terrain. Oh, and the crappy OEM-style brakes on my ‘71 Celica. Forgot I warped a rotor on it too after upgrading the master, prop valve, and pads. Those brakes were a joke even on a ~2K pound car.
