Please Help Mercedes C240 2001, brake suddenly while driving.?
 

I have Mercedes C240 model 2001, since 2 weeks the car while I am driving breaks suddenly by it self then dashboard showing ESP error, it is happening while I am driving straight.
One machanic told me to replace brake light switch and I did, but the broblem still there also I replaced the battery and problem still there.

This happened many times, any ideas?

There is any way to stop this process (ESP or breaking process)?

check your tire sizes. they should be the same. did you get tires replaced?

All tires are same size.
