Which suspension component is primarily responsible for controlling wheel motion during braking?

The strut assembly is primarily responsible for controlling wheel motion during braking. When a vehicle brakes, weight transfers forward, which can affect the stability and handling of the vehicle. The strut assembly, which integrates a shock absorber and a coil spring, plays a critical role in managing these dynamics.

As the vehicle slows down, the struts provide the necessary damping to reduce excessive oscillation and help maintain tire contact with the road surface. This stability is crucial for effective braking performance and overall vehicle control. The strut assembly also aids in maintaining alignment and reduces the possibility of the suspension components becoming unresponsive during these dynamic conditions.

While other components like the shock absorber, control arm, and sway bar contribute to the overall function of the suspension and vehicle handling, the strut assembly is specifically designed to respond to both the impact of road irregularities and the forces exerted during braking, ensuring that the wheels remain properly aligned and perform optimally.
