ABS BRAKE PROBLEM COLORADO Cpmes on when cold and I hear at low speeds a VvVVVr sound and then the abs lite stays on for about 15mins and then gos away The brakes are new and new roters, It did this befor I did a brake job also Braskes work fine just when I do my low speed breaking when tthere cold!

SOURCE: Abs/Brake Light ON, although new brakes, ABS still works

I would suspect a speed sensor.

SOURCE: Dash board parking brake and ABS lights stay

you have an abs fault. have your abs system scanned for codes.

your base brakes will continue to function normally

SOURCE: ABS brakes grunt, groan noise with brake pedal travel.

Joe it is common for the brakes to moan when they wear down and sometimes they will squeak, try replacing the front pads and lubing the shafts on the calipers install anti squeal on the back of the pads, the ABS device would not cause noise as they are just a ring with a magnet and the reluctor ring spins and the magnet detects the spinning of the reluctor ring, they don't even touch and are stationary in place where they are mounted. There is a possibility that the brake fluid is dirty and could cause the abs motor to groan but you would just have to flush the system, When you don't put your foot in it on the brakes it will make some noise even new, I have a 2008 ford ranger that makes the same noise and the brakes are fine. You will have to adjust your braking habits to stop the noise. You can change the pads and that will help but not for long, be sure when you are operating your brakes press firmly on the pedal until you stop. If the brakes make noise after you let up on the pedal then the caliper parts need to be cleaned and lubed, however it is not a safety issue.

You most likely have a bad wheel speed sensor. if you have it scanned it should tell you which one it is, If that is the problem. you need to make sure that the scanner used Will read ABS codes

Because the brakes were changed, either one of the sensors were broken when removing brakes or it has set a code. Go to your local autoparts store and have them reset the code. See if it comes back on. If it does you will need to look at the ABS sensors on each wheel and replace if damaged
