Good morning,

This sounds like one of the ABS sensors is causing this issue. The mountings get dirty with road dirt and cause signal issues.

I would clean all the mounts with a wire brush and then reinstall and tighten the sensors. Then road tests it and sees if it still happens.

If it does, then you will need a scan tool that can monitor wheel speed to see what sensor is causing the issue.

I attached the procedures for removing the sensors for cleaning.
