Hi, welcome to Just Answer. My name is***** you referring to the brake pad wear sensors?
Hi, I need to know which sensor you are trying to replace. Is it the pad wear sensor or the ABS wheel speed sensor?
Ok, the wear sensors just push into the brake pad. You don't actually need to remove the brake pad but you will need to remove the retainer to get good access to the front sensor and you will need to remove the rear caliper to gain access to the rear sensor. I've attached instructions for replacing the front and rear brake pads below which will provide you with all the instruction you need to replace the sensors. Let me know if you have any questions.
