Warped rotors AGAIN!?!?!

[dolvio]

Has anyone come across this yet? We do a mix of one pedal and normal to burn rust off sometimes and I’ve got warped rotors for the second time. The vibrations are violent at higher speeds. What the issue here?

We just traded a
In a Lexus NX350 for a Mach e. The Lexus had several issues plus warped rotors at 50000 miles. I don’t like hearing you have that issue on a Mach e.

There have been many members here with well over 100K miles that have never had any issues either with their rotors or even replaced pads me included. I live in the foothills if the sierras and drive lots of mountainous roads. Something has to be wrong with the setup or the roads you drive.

Yea, i have 80K on my 21 and never had an issue and still on original pads as well

Same here: More than 155K miles on our two Mach-Es and no problems with warped rotors.

Of course, because the regen brakes are so efficient, we seldom use our brake pedals..

I think that’s maybe what’s causing this. The 1 pedal.

The regen brakes are an independent system. They don't use the brake rotors, so regen braking couldn't be the source of your warped rotors...

They definitely use the brakes. In my case I can feel the vibrations from the warped rotors. It’s a hybrid system.

The regen system engages wheel generators to produce electricity for replenishing the HVB while the drag from the generators slow down the car. They have noting to do with rotors. On the other hand, if you press the brake pedal hard enough you will engage mechanical braking, regardless of 2 pedal setting.

One pedal driving, especially at higher speeds, 100% utilizes the brakes as well.

You’re reading but not comprehending. Both 1pd and 2pd can use the mechanical brakes, but only if you push the brake pedal far enough. How far? That depends on on your brake mode. In 1pd drive mechanical braking occurs as you approach a panic stop level of braking. In 2pd mechanical braking occurs sooner, but before panic stop hard. The regenerative braking system at no time uses rotors, it uses generators, nothing more.

Correct Bill. The ONLY time physical brakes are used during 1PD is if the HVB is at 100% SOC and cannot take any more charge from the regenerative braking system and when you are going a very slow speed coming to a stop.

Maybe this is the OPs problem... his Regen is broken and not being used at all; all braking is from the rotors. When the battery is near 100% the regen is not used. Maybe there is a fault where the car thinks it cannot use regen.

I was going to ask if he drives using his right foot for accelerator and left foot for brakes. Some people who do this relax their left foot and ride their brakes for miles and miles. But this would not explain the warped rotors if his regen is working properly.

 

[EagleDave]

Can he try the Brake Coach to see if his regen is working?

I think some folks are confusing 1pd with the regenerative braking system. Both 1pd drive and 2pd use the regenerative braking system, but they are quite separate. 1pd or 2pd are just looking for a deceleration profile, regenerative braking is one of the tools each use to meet the deceleration profile.

Be all that as it may Mark, neither 1pd nor regenerative braking are causing the warped rotors.
