Brake Caliper Seized or Parking Brake Stuck
The vehicle is in gear but won't move when the engine is cold, suggesting a brake or steering issue. This is likely due to a seized brake caliper or a stuck parking brake mechanism, which prevents wheel rotation.
Diagnosis Details
Possible Causes
Seized brake caliper piston or slide pins due to corrosion or lack of lubrication, causing the brake pad to remain pressed against the rotor.
Parking brake cable or mechanism frozen or stuck, especially in cold weather, preventing the rear wheels from turning.
Brake hose internal collapse or blockage, trapping pressure in the caliper.
