I need some help here... I have a 2000 chevy blazer 4x4 4 door. My brake light came on one day and i got out and had a buddy push my brakes as i looked unnder my truck. It looks to be that its leaking somewhere at my rear passenger tire, getting the inner side of my tire wet. Any ideas on what that may be? And what needs to be replaced?

 

Could be metal line, rubber hose or caliper. You will have to get under there and look

 

Finding out what's leaking is almost as easy as changing a tire (except You put the old one back).
