I recently bought a new bike. It is a Scott bike with disc brakes. The bike went in for it's service and now it has problems braking. As soon as I pull the brake leavers the front brakes makes a loud squeaking noise. The front brake disc is a blueish color from trying to brake.
The back brake works perfectly. I took it back to the people who serviced it, and they were unable to solve the problem. Do you know what the problem could bee and how to correct it?
