ok I have a 03 silverado ext cab a while back I dropped it but I broke the abs wire in the right front tire but left it like that then got it tuned now I bought the abs and put it on now when I brake the left front caliper makes a vibrating noise when it comes to a complete stop im guessing it had to do something to do with the tune .thank you in advance for your help

 

I dont see how a tune could screw with your brakes.

 

I disconnected the abs wire and it stoped making that noise

 

Sounds like your brakes are messed up. There is nothing in the tune that adjusts the brakes.

 

oh ok do you have any idea what can it be

 

tttttt

 

First ohm out the sensor, if it's OK then try cleaning the connector.
