Brake cylinder air leakage can affect braking performance and is unsafe. Here is the relevant introduction: 1. Brake booster pump: The brake booster pump, also known as the brake assist pump, controls the vacuum entering the booster pump during braking, causing the diaphragm to move. Through the linkage device, the pushrod on the diaphragm assists the driver in pressing and pushing the brake pedal, thereby amplifying the force applied by the driver. 2. Causes of damage: The common causes of cylinder damage are oil leakage or poor return. Oil leakage can be easily identified, while poor return can be judged based on the wear condition of the brake discs and pads.

Can traffic violations in another location be handled locally?

Whether traffic violations in another location can be handled locally depends on the situation: 1. For non-on-site violations (such as electronic monitoring or parking tickets), the penalty can be accepted and the fine paid in the vehicle's registered location. 2. For on-site penalties (issued by traffic police in person), the fine must be paid in the location where the penalty was issued. Methods for handling violations in another location: 1. Go to the local traffic management department to accept the penalty, bringing your driver's license and vehicle license or copies. 2. Have a friend in the violation location handle it for you. If you have a friend in the violation location, you can send them the original or copies of the violation notice, driver's license, vehicle license, ID card, etc., and ask them to handle it for you. 3. Use car clubs or other related agencies that offer services for handling violations in another location. These agencies usually charge a fee. 4. Postal services offer payment services for traffic violation fines in another location, allowing vehicle owners to pay fines without leaving home, saving time and costs.

Does the steering wheel control the front or rear wheels?

The steering wheel controls the front wheels, while special vehicles may control the rear wheels. The steering wheel only controls the front wheels for steering, continuously adjusting their direction. Common household cars, sedans, and MPVs typically use front-wheel steering, whereas special vehicles like forklifts and large excavators employ rear-wheel steering. The car steering wheel is connected to the steering shaft via splines, converting the driver's force applied to the wheel's edge into torque transmitted to the steering shaft. Common buttons on a car steering wheel include: 1. SET for speed setting; 2. CNL for canceling cruise control; 3. RES for resuming cruise control; 4. Up and down for volume adjustment.

Do External Tire Pressure Monitors Require Wheel Balancing?

External tire pressure monitors generally do not require wheel balancing. The principle of external tire pressure monitoring sensors is to use a needle to open the tire valve, allowing the sensor to measure the internal tire pressure directly. The sensor cleverly utilizes the thread of the dust cap to secure itself to the valve stem. Tire pressure monitoring works by recording tire rotation speeds or using electronic sensors installed inside or outside the tire to automatically monitor various tire conditions in real-time, providing effective safety assurance while driving. The installation method for external tire pressure monitoring sensors is as follows: 1. Unscrew the dust cap from the valve stem and place the dust cover over it; 2. Install the hex nut and attach the tire pressure sensor; 3. Tighten the sensor using a nut wrench to complete the installation of the external tire pressure sensor.
