I just got my K5 on the road, the first couple of days everything was running great, no wierd noises nothing like that. After a few days i started getting a loud squeak coming from the back of the blazer. I know it is something to do with the brakes, when ever i am rolling it squeaks until i hit the brakes then it stops, any idea what this could be? The colder it is outside it seems the louder it is, but when i drive down the highway or am doing a constant speed for a long period of time it will stop until i hit the brakes then it starts again. It stops fine, and doesnt make any noises when the brakes are engaged. Any help would be greatly apprciated. Thank you!
