Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi and thanks for your question! I have not see major problems with the brakes. I did a bulletin search for you and I did find two. I will send them to you. Please don't tell them where you got these, they do not like us helping you. They will come in a few posts.
Thank you Ken
Some customers may comment on ABS activation at low speeds, usually below 8 km/h (5 mph). Upon investigation, the technician will find no DTCs set.
The cause of this condition may be an increased air gap between the wheel speed sensor and the hub reluctor ring due to rust and debris built up on the sensor mounting surface.
Measure AC voltage and clean the wheel speed sensor mounting surfaces.
