hello all. I have a problem. my car's abc system works perfectly, sometimes I drive for 3-4 hours about 500 km without stopping but sometimes after half an hour's drive, only one side, the front left side goes down. and sometimes goes up very slowly or sometimes does not go up. in this case, I turn the car off and after 20-25 minutes start it up, and it works perfectly.

I think there is some abc valve problem.
