Service Stabiltrac Light on and Brakes grind while turning.
 

When i turn the car on everything is fine but once I move the car forward an inch I get the service stabilitrak message that stays on with the traction control, stabilitrak, and competitive mode lights. They all stay on and the button on the center console doesn't work while these lights are on. Also while I drive if i turn my wheel more then 90 degrees in either direction while braking my brakes grind and the car DOES NOT STOP. I have to turn the wheel straight to stop. I have almost crashed at least 5 times. I am extremely scared to bring my car to the track (don't worry I will not be bringing it). But seriously tho why lol. I have a ton of mods done to the car but idk whats going on still.

Any CEL or codes?

If your brakes are grinding I would check to make sure you still have pad surface on them. Even if the system is engaging them for whatever reason they shouldn't be grinding.

Nope only service stabiltrak on the dash

My brakes r brand new

So your losing all braking capabilities when you turn your wheel 90 degrees? Does ABS activate? Do you lose pedal? You are losing something if braking fails.

Can you tell what corner the grinding is coming from?

edit: Brakes aren't supposed to grind. If you just had them installed I would double check them. Perhaps they were installed improperly.

When i turn the steering wheel and press the brakes the brake pedal doesnt go more then 5% down and it just grinds. But if i pump the brakes it will eventually go. abs doesnt activate

I cannot tell what side they are grinding from, and I checked the brakes 100 times to see if they were installed correctly, they surely are lol.

Suggestion... roll down both windows and have someone ride with you and listen to hear what side the noise is coming from or both sides.

Grinding or squealing?

Ok

Grinding

I may have found the reason for the stabiltrak BS. Chevy said the light might come on If I have after market wheels. I am running 305/30/19 all around lol. I'm gonna throw my stock wheels back on and see what hapoens.
