For the last two months the front left brake would lock up while driving in town. I had the caliper and rotor replaced first. The following day the brake locked up again. At the shop a mechanic told me how GM put inferior brake hoses on their vehicles. The tube inside the hose would get pinched or close partly which prohibited the fluid from steadily passing through the hose. Once the brake hose was replaced the brakes stopped locking up.

The problem is when I drive for so long the brakes start to lock on me. It start smoking and I have to sit in the car for hours until it cools down. Then the brakes start locking again and smoking and the problems repeats itself again.
