Chevrolet equinox 2005 abs light is on. After scanning the speed sensor(at passengers side) has been replaced but afterwards I have the same problem . The pedal keeps vibrating with a strange noise till the abs light goes on.the brakepads has also been replaced.
What is the solution?

. Clean all ABS sensors with WD-40 and a rag.

. Check the brake calipers. The pistons may not be retracting properly. Lubricate the caliper pins with silicone grease. Replace calipers and pads, if necessary.

. Change all of the brake fluid (Valvoline ABS Brake Fluid). This is extremely important on ABS. Do it every 2 years.
