I have a 2002 Buick Century w/74,000 miles and a problem with the brakes.
I have a 2002 Buick Century w/74,000 miles. When I apply the brakes they sometimes
make a noise like a sick cow and push back, but they didn't do it when I left the car for
the mechanic to drive. Yesterday the anti-lock brake light came on and the noise and
push-back intensified. What might be the problem, and is it very expensive to repair?
