Why is there a clicking sound when turning the steering wheel while braking in place?

Here are the reasons for the abnormal noise when turning the steering wheel while braking in place: Ground friction sound: The main cause of the abnormal noise is the friction noise between the car tires and the ground, as well as noises from the brake discs, steering system, suspension system, etc. When the car turns the steering wheel in place, the steering wheels do not rotate around their own geometric centers but roll slightly, because the rotation center of the tire is not at the geometric center of the tire but at the rotation center of the steering knuckle. Therefore, from a microscopic perspective, the wheels perform a circular rolling motion centered on the axis of the steering knuckle when turning the steering wheel in place. Power steering issue: The abnormal noise when turning the steering wheel in place mostly occurs in models with mechanical hydraulic power steering (HPS). Mechanical hydraulic power steering, abbreviated as HPS, is mature in technology and low in cost. This type of power steering converts part of the engine's power into hydraulic pump pressure, which then applies pressure to the steering system, thereby turning the tires. When the steering wheel is kept straight ahead, the pressure on both sides of the piston is the same. Once the steering wheel is turned, the mechanical control valve connected to the steering column will open.

That noise is really annoying. I've encountered a similar situation when driving in winter—when stepping on the brake and turning the steering wheel in place, it makes a clunking sound, especially noticeable when moving slowly in parking lots. This is most likely an issue with the steering system, such as friction in the steering gear or power assist motor under heavy pressure, or a loose gap between the brake pads and discs. When turning the steering wheel in place, the steering load is high, and if the components are old or worn, they are prone to making noise. It's advisable not to delay and take the car to a repair shop as soon as possible for inspection. They can use diagnostic tools to check the power steering or brake caliper condition to prevent a minor issue from turning into a major, more expensive repair. Also, try to minimize turning the steering wheel in place when parking to protect the steering components.

I've encountered this issue myself. As someone who enjoys tinkering with cars, I know that the sound when stepping on the brakes and turning the steering wheel is usually caused by wear in the steering linkage or ball joints. Performing these operations while stationary concentrates pressure and may lead to enlarged component gaps, resulting in noise. When inspecting it myself, I first turn off the engine, then manually shake the steering tie rod to check for looseness, or examine if the brake caliper is deformed - but be careful to avoid hand injuries. If it's a simple issue like replacing a ball joint, that might solve it, but for more complex situations, it's better to have a technician handle it to prevent the risk of steering failure. Regular lubrication of components can prevent this problem - don't wait until issues arise before taking action.

This clunking sound is very dangerous. Having driven for many years, I always remind others to be cautious. Pressing the brakes and turning the steering wheel while stationary already increases the system load. The noise could be caused by a failing power steering gear or loose brake components. If not addressed promptly, the steering may suddenly lock up, increasing the risk of an accident. It is recommended to stop the operation immediately upon discovery, pull over to the side of the road, and contact professional maintenance for inspection to ensure precise and safe steering. Don't try to save on this small expense. Regularly check the tightness of connection points during routine maintenance.
