First off, ive searched, and found a few little things about the ABS acting up, some people say change brakes, ABS sensor, etc. However I didnt find anything about the ABS acting up ONLY during cold weather.

My issue-
Once the weather drops below around 45 degrees or so, when I step on the brakes I can feel what im guessing is the ABS acting up. Makes an awful noise and jerks/hesitates while on the brakes. NO lights, nothing comes up on the dash, simply just the ABS is engaging bad. I felt at first maybe it was a sensor, but figured if that was the case it would do this no matter how cold it is. Just looking for a solution to this issue because its annoy and feels dangerous driving the Z when its cold out, which is most of the time in WV until april/may. FYI, its an 05 touring.

Any input is appriciated.
Thanks

 

what kind of noise is it making?

 

kinda hard to explain, its like a grinding type noise. It just sounds like the ABS is engaging when im on the brakes in the cold. Its a hesitating grinding noise when on the brakes.

 

It could also be referred to as a clunking noise, or as ive seen before kinda of like a guitar string breaking. Maybe just need to clean the sensors? any help is appreciated.
