The reasons for a brake pump failure are: 1. Dirty brake fluid causing wear on the wheel cylinder; 2. Aging and wear of the wheel cylinder rubber cup; 3. Poor sealing. The brake wheel cylinder is a chassis braking component of the braking system, whose function is to push the brake pads, allowing them to rub against the brake drum, thereby reducing the vehicle speed and bringing it to a stop. The brake master cylinder, also known as the main brake oil cylinder, functions to push brake fluid and gas to each brake wheel cylinder to actuate the pistons. The brake master cylinder is a single-acting piston-type hydraulic cylinder that converts the mechanical energy input by the pedal mechanism into hydraulic energy. Brake master cylinders are divided into single-chamber and dual-chamber types, used in single-circuit and dual-circuit hydraulic braking systems, respectively.

Why Does the Cayenne Make Abnormal Noises During Acceleration?

Cayenne making abnormal noises during acceleration may be caused by excessive throttle clearance. Reasons for abnormal noises: Engine abnormal noises indicate that the technical state of a certain mechanism in the engine has changed. This is mainly caused by excessive wear of some parts or improper assembly and adjustment. The transmission has many components, making the reasons for the noises relatively complex. Solutions: Abnormal noises can also serve as a warning that the engine may suffer from serious damage. Therefore, when abnormal noises occur in the engine, timely repairs should be conducted to prevent the fault from worsening. If the abnormal noise is inside the engine, most car owners cannot fix it themselves, and it is best to send it to a factory for inspection and repair. If the transmission noise is obvious, it is still recommended to send it to a professional repair shop to identify the faulty component and then replace it.

Should the power cables be disconnected when charging a car battery?

It is recommended to disconnect the power cables when charging a car battery, because the car's electrical circuits remain active even after the vehicle is turned off and locked. For instance, the control circuits for the car doors continue to operate - when using the remote key to lock/unlock the vehicle, the doors will automatically open/close. Therefore, if you connect an external charger to the battery without removing it from the vehicle, it may potentially damage the remote door control system. The principle of car battery charging: The charger's voltage must be higher than the battery's voltage to enable charging. The greater the electromotive force difference between them, the faster the charging speed and the larger the charging current. Typically, a 24V charger has a maximum (no-load) voltage of 28V, with 60A indicating its maximum output capacity. When charging, the charger is under load, at which point the voltage becomes the actual charging voltage of the battery, with 40A representing the charging current. This current will gradually decrease as the charging process completes. Additionally, the charging current magnitude also relates to the battery's capacity size.

Is it necessary to change the oil filter?

Yes, it must be changed. When performing car maintenance, it is necessary to replace the engine oil with qualified products and change the oil filter at the same time. This ensures better usage of the engine oil and effectively filters out impurities within the oil, preventing long-term clogging issues. Below is relevant information about oil filters: 1. Location: The oil filter is typically located in the engine's lubrication system, with its upper part connected to the oil pump and the lower part connected to various components within the engine that require lubrication. Generally, the oil filters used in car engines are non-cleanable disposable filters, so the oil filter needs to be replaced along with the engine oil during maintenance. The oil filter is also one of the car maintenance items, usually requiring replacement every 5,000 kilometers. 2. Function: The role of the oil filter in the engine is to filter out harmful substances from the engine oil, ensuring a good working environment for components such as the crankshaft connecting rod and turbocharger, and providing lubrication and cleaning functions.

After completing the tax payment certificate, you need to take photos of the original invoice, vehicle license, motor vehicle registration certificate, and tax payment certificate, and send them to the 4S store. The scope of new energy vehicle subsidies includes: 1. Three forms: Private purchase and use of new energy vehicles include direct purchase, vehicle leasing, and battery leasing. 2. Direct purchase: The central government provides subsidies to automobile manufacturers, who sell new energy vehicles to private users at the price after deducting the subsidies. 3. Vehicle leasing: The central government provides subsidies to automobile manufacturers, who sell new energy vehicles to leasing companies at the price after deducting the subsidies. 4. Battery leasing: The central government provides subsidies to battery leasing companies, which rent new energy vehicle batteries to private users at the price after deducting the subsidies and provide services such as battery maintenance, repair, and replacement.
