I have problem with the car listed above (Korea). When I put my foot on the brake I hear noise and feel regular vibration still until 5 second and disappear, and this is continuously happening.

One time when I am driving there was an error message "check brake ", and when I restart the car, the message went away.

can you help me to resolve this problem please?

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.
