A vehicle pulls to the right only while braking. Which of the following could be the cause?

When a vehicle pulls to the right only during braking, the most likely cause is a problem with the braking system or its components. A loose cradle can lead to misalignment of the suspension or steering components, particularly when the brakes are applied. This misalignment can cause one side of the vehicle to engage the brakes differently than the other, resulting in a pull to one direction.

A loose cradle may affect the suspension geometry or the way the weight is distributed during braking, which is critical for maintaining balanced braking force. When the vehicle has uneven braking pressure, especially at the front where most braking occurs, it can lead to a pull towards the side that is experiencing less braking force.

In contrast, underinflated or overinflated tires can lead to uneven wear or handling issues over time, but these factors typically cause pulls that are not specific to braking. Similarly, a loose power steering pump belt would affect steering control rather than causing a pull only when braking. Therefore, the loose cradle directly contributes to the vehicle's tendency to pull to one side during braking, making it the correct identification of the issue.
