Truck brakes not returning to position can be caused by the following reasons: 1. Poor lubrication of the brake wheel cylinder: Lack of oil in the brake wheel cylinder can affect its return, which can be resolved by applying grease. 2. Faulty brake shoe spring: If the spring tension of the brake shoe is too weak, it may fail to return, and replacing the spring can fix the issue. 3. Damaged wheel cylinder rubber cup: If the rubber cup of the wheel cylinder is damaged, causing insufficient air pressure, it will affect the brake's return. 4. Faulty return spring: If the return spring on the brake pedal is improperly installed or has fallen off, it can prevent the brake from returning to position.
