My front brakes are locked up on my 2005 GMC Envoy, and won't release.
Are you sure it is the brakes. Could be drive train related. If it is brakes it may just be one side. Lift a wheel at a time and see if it is both. Could be the caliper slides are rusted and stuck engaged. Could be a brake hose to the caliper is torn inside and not releasing the fluid back. Or the caliper piston is stuck from corrosion.
