1. Brake Booster Failure: The brake booster is a device that helps to assist the driver in applying pressure to the brakes. If the brake booster fails, it can cause the brake pedal to become hard and difficult to press. This could be a result of a vacuum leak, a faulty brake booster check valve, or a problem with the brake master cylinder.
2. Power Steering Failure: The power steering system helps to reduce the effort required to turn the steering wheel. If the power steering system fails, it can cause the steering wheel to become tight and difficult to turn. This could be caused by a low power steering fluid level, a faulty power steering pump, or a problem with the steering rack.
3. Mechanical Binding: If there is a mechanical binding between the steering and brake systems, it can cause the steering wheel to lock up and the brake pedal to become stuck. This could be caused by a damaged or misaligned steering rack, a faulty tie rod, or a problem with the suspension components.
It's important to have these issues diagnosed and repaired as soon as possible, as they can affect the safety and operability of the vehicle. If you are experiencing these problems, it's best to have the vehicle towed to a reputable mechanic for inspection and repairs.
