The brakes, suspension, and steering systems are all major safety components of any vehicle. If something is going wrong with one of them it can seriously affect the performance and the safety of the car.
\n\nThere can be simple issues such as worn brake pads, the wheels being out of alignment or leaking steering fluid to the more severe issues like a warped rotor, bad tie rods or failing struts.
\n\nRegardless of the issues, getting the brakes, suspension and steering systems inspected and repaired is key to making the car safe to drive.
\n\nBrakes
\n\nBrakes are available as disc or drums, older vehicles tend to have drum brakes while new models incorporate disc brakes. Both systems use friction and resistance to bring the vehicle to a stop.
\n\nDisc brakes have a rotor that is connected to the wheel. Brake pads grind against the rotor, creating friction, which brings the car to a stop. Over time, brake pads and rotors will wear down and have to be replaced.
\n\nDrum brakes work on the same principal. A drum is attached to the wheel and when the brake pedal is depressed, brake shoes press against the drum, slowing the vehicle. Brake shoes, like pads will wear out over time.
\n\nSuspension
\n\nThe job of the suspension system is to maximize the friction between the tires and the road, as well as provide stability to the steering system. There are a number of different suspension systems. The main components of the suspension system are struts, shock absorbers, springs and tires.
\n\nThe springs help to support the weight of the vehicle, they also maintain ride height, and absorb bumps in the road.
\n\nThe shocks reduce the up and down motion of the car that is produced when the vehicle hits bumps on the road or highway.
\n\nStruts replace the shocks and springs on some vehicles. They combine the shock and spring into a single unit.
\n\nTires keep the vehicle in contact with the road and provide traction to make driving safe.
\n\nSteering System
\n\nThe steering system takes the rotation of the steering wheel and converts into the swiveling motion of the wheels.
\n\nA rack and pinion system uses a gear set that is enclosed in a metal tube. Both ends of the rack protrude from the end of the tube. A tie rod connects to each end of the rack and the pinion gear is attached to a steering shaft. As the steering wheel is turned, the gear spins which moves the rack.
\n\nBrakes
\n\nLoss of Hydraulic Pressure: The brake system uses hydraulic pressure to push the brake pads against the rotors. If there is a leak in the hydraulic system the brakes will not provide the correct stopping power.
Worn Brake Pads: Brake: Brake pads will wear out over time. The have a indictor that will make contact with the rotor and produce a squealing noise when they get too thin. If the brakes are squealing the pads should be replaced. If the squealing turns into a grinding noise, the pads have worn through completely, this can damage the rotors which is a much more expensive repair.
Stuck Caliper: The calipers push the brake pads against the rotors. If a caliper gets stuck the vehicle will pull to one side. A failing brake hose can cause this issue.
Warped Rotors: If the rotors are exposed to stress, such as towing or mountain driving, they can warp. Warped rotors will cause the vehicle to vibrate and shake while braking.
Worn Brake Shoes: This is basically the drum brake version of worn brake pads for disc brakes. The shoes will squeal when they are too thin and need to be replaced. A grinding noise indicates shoes that have been worn through completely.
Suspension
\n\nWorn Shocks or Struts: In most vehicles the struts will eventually wear out and need to be replaced. If you notice excessive bouncing when going over bumps, or the vehicle nosedives when braking, it may be time to replace the shocks or struts.
Uneven Tire Wear: A failing suspension system can lead to uneven tire wear as the system is not holding the wheels even on the road at the proper angle. Look for bald spots on your tires. Suspension problems should be inspected and repaired as soon as possible.
Bad Spring Coils: In most cases, spring coils will last the life of the car but they can break. If the vehicle is not driving smoothly or leaning heavily to one side, it could be an issue with the spring coils. This should be fixed immediately.
Leaking Shocks: Shocks will often have to be replaced over the life of a car. If there is oil leaking on the garage floor or a leak is visible from the shocks, it is time to get them replaced.
Steering
\n\nBad Tie Rods: Tie rods are the component that connects the steering linkage to the wheels of a vehicle. Eventually tie rods will wear out. As they do the vehicle will go out of alignment and wear the tires faster. There may also be a squeaky sound and the steering wheel may be harder to turn.
Loose Lug Nuts: Something as simple as a loose lug nut will cause the steering wheel to shake. This is a fairly easy problem to fix.
Unbalanced Wheels: This problem can also cause the steering wheel to shake at certain speeds. At higher speeds this can become dangerous. The tires should balanced as soon as possible.
Steering Gearbox Not Responding or Hard to Steer: if the steering wheel does not seem to be responding properly or it is hard to steer this can indicate a problem with the steering gearbox. This issue can quickly become dangerous. The steering system should be inspected and repaired as soon as possible.
Power Steering Malfunction: The power steering component can malfunction for a number of reasons. Fluid may be leaking due to damaged seals on the power steering pump, or there could be a leak in one of the power steering hoses. A whirring or siren-like sound coming from the steering pump can be an indicator of this problem.
Power Steering Pump: A failing power steering pump can make the steering wheel hard to turn and it may make a groaning noise when the wheel is turned. A failing pump will eventually die and need to be replaced.
A top-\u00adrated mobile mechanic will come to your home or office to determine the source and cause of the brake, suspension or steering issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
\n\nAll three of these systems are vital to the safety of the vehicle. While some issues with these systems will be more of an inconvenience than a safety issue, other problems can lead to dangerous driving conditions and the problem should be addressed as soon as possible.

制动器,悬架和转向系统都是任何车辆的主要安全组件。如果其中一个出现问题,它可能会严重影响汽车的性能和安全性。
可能存在简单的问题,例如磨损的刹车片,车轮不排列或泄漏转向液体到更严重的问题,例如翘曲的转子,不良的拉杆或支撑杆故障。
不管问题如何,检查和维修刹车,悬架和转向系统是使汽车安全驾驶的关键。
刹车
刹车可作为圆盘或鼓,较旧的车辆往往具有鼓制动器,而新型号则融合了盘式制动器。这两个系统都使用摩擦和电阻将车辆停止。
盘式制动器具有连接到车轮的转子。刹车垫在转子上磨碎,产生摩擦,从而使汽车停止。随着时间的流逝,刹车片和转子将磨损,必须更换。
鼓制动器在同一校长上工作。将鼓连接到车轮上,当制动踏板凹陷时,刹车鞋压在鼓上,减慢车辆。刹车鞋,就像垫子一样,随着时间的推移会磨损。
暂停
悬架系统的工作是最大化轮胎与道路之间的摩擦,并为转向系统提供稳定性。有许多不同的悬架系统。悬架系统的主要组成部分是支柱,减震器,弹簧和轮胎。
弹簧有助于支撑车辆的重量,它们还保持行驶高度并在道路上吸收颠簸。
当车辆在道路或高速公路上撞击时,震动减少了汽车的向上和向下运动。
支撑杆代替了某些车辆上的冲击和弹簧。他们将冲击和弹簧结合到一个单元中。
轮胎使车辆与道路接触并提供牵引力以使驾驶安全。
转向系统
转向系统采用方向盘的旋转,并转换为车轮的旋转运动。
机架和小齿轮系统使用封闭在金属管中的齿轮套件。架子的两端从管的末端突出。一根拉杆连接到机架的两端,小齿轮齿轮连接到转向轴上。当方向盘转动时,移动机架的齿轮旋转。
刹车
液压损失:制动系统使用液压压力将刹车片推向转子。如果液压系统泄漏,制动器将无法提供正确的停止功率。
磨损的刹车片:刹车:随着时间的推移,刹车片会磨损。有一个检测器,它将与转子接触并在太薄时产生尖叫声。如果刹车尖叫,则应更换垫子。如果尖叫变成磨损的噪音,垫子已经完全磨损了,这会损坏转子的修理,这是一个昂贵的修复。
卡尺:卡尺将刹车片推向转子。如果卡尺被卡住,车辆将拉到一侧。故障刹车软管可能会导致此问题。
扭曲的转子:如果转子承受着压力,例如牵引或山上驾驶,则可以扭曲。扭曲的转子会导致车辆在制动时振动和摇动。
磨损的刹车鞋:这基本上是用于盘式制动器的磨损制动垫的鼓式制动器。鞋子太薄,需要更换时会尖叫。打磨的噪音表示已经完全穿过的鞋子。
暂停
磨损的冲击或支柱:在大多数车辆中,支柱最终会磨损,需要更换。如果您发现在颠簸时出现过多的弹跳或制动时的车辆鼻子,则可能是时候更换冲击或支柱了。
轮胎磨损不均匀:失败的悬架系统可能会导致轮胎磨损不均匀,因为该系统即使以适当的角度在道路上也无法固定车轮。在轮胎上寻找秃头。悬架问题应尽快检查和修复。
不良的弹簧线圈:在大多数情况下,弹簧线圈将持续汽车的寿命,但它们可以破裂。如果车辆没有平稳行驶或倾斜在一侧,则可能是弹簧线圈的问题。这应该立即修复。
泄漏的冲击:冲击通常必须在汽车的生活中更换。如果车库地板上有漏油或从冲击中可以看到泄漏,那么该更换它们了。
操舵
不好的拉杆:拉杆是将转向连杆连接到车轮的组件。最终,拉杆会磨损。当他们这样做时,车辆将摆脱对齐方式,并更快地穿轮胎。也可能有吱吱作响的声音,方向盘可能更难转动。
松散的凸耳螺母:像松散的凸耳螺母这样简单的东西会导致方向盘摇动。这是一个很容易解决的问题。
车轮不平衡:此问题还会导致方向盘以某些速度摇动。在较高的速度下,这可能会变得危险。轮胎应尽快平衡。
转向变速箱不响应或难以转向:如果方向盘似乎没有正确响应,或者很难引导,这可能表明转向变速箱有问题。这个问题可能很快变得危险。应尽快检查和修理转向系统。
动力转向故障:动力转向组件可能出于多种原因出现故障。由于动力转向泵上的密封损坏,流体可能正在泄漏,或者一支动力转向软管可能会泄漏。转向泵发出的呼啸声音或警笛声可以指示此问题。
动力转向泵:故障的动力转向泵可能会使方向盘难以转动,并且在转动车轮时可能会发出gro吟声。故障泵最终将死亡,需要更换。
最高的移动机械师将来到您的家庭或办公室,以确定制动器,悬架或转向问题的来源和原因,然后提供详细的检查报告,其中包括必要维修的范围和成本。
这三个系统对车辆的安全至关重要。尽管这些系统的某些问题比安全问题更具不便,但其他问题可能会导致危险的驾驶条件,并且应尽快解决该问题。
