05 Trailblazer brakes are constantly deployed. Runs good first couple of miles the. Brake pedal gets hard and truck will come to a stop if not giving it gas. Drive it til it locks up and got tires in the air, all 4 are locked up. Calipers are New. Brake Lines are New. Bad ABS sensor, Hubs were replaced. ABS disengaged by removing fuse and still does same thing. If Master Cylinder or Booster were bad I'd have less or no brakes... My problem is too much brakes. Any Ideas?
