Nissan patrol ABS and Braking issues

[Gesi]

Hello everyone, I need some advice on how to tackle the issues I’m having with my patrol. I have an issue where my abs light is constantly on followed by a braking issue that requires me to hard step on the brake paddle for the car to come to a stop (even at very low speeds). This has made it impossible to drive. I got a few mechanics and they have changed the abs twice now but to no avail. Please any help would be appreciated.
