How do you know if your trailer is equipped with antilock brakes?
Answer: Trailers built after 1998 are required to have ABS. One way to check is by looking on the left side of the trailer there should be a yellow ABS malfunction light either at the front or rear of the trailer.
Another way is looking at the brakes them selves if there is any electrical line running to the brakes it most likely is leading to the speed sensor which means those wheels have ABS
