How to Change Brake Fluid for a Car?

Method for changing brake fluid for a car: 1. Park the vehicle on a flat surface, open the engine hood after turning off the engine, and use a syringe to extract the fluid from the reservoir until the bottom is reached; 2. Fill the reservoir with new brake fluid, using a funnel during pouring to avoid spilling onto the engine compartment, as brake fluid is corrosive; 3. Use a jack to lift the vehicle, starting with removing the rear wheels first; 4. Locate the bleeder screw on the brake caliper and remove the rubber dust cap on it; 5. Use a wrench to loosen the bleeder screw, attach a rubber tube to it, and connect the other end to a drain bottle; 6. Inside the car, press the brake pedal, observing the color of the brake fluid in the rubber tube. Old fluid is darker, while new fluid is lighter. If the fluid coming out of the tube is the lighter new fluid, the fluid change for that wheel is complete. Stop pressing the brake pedal and reinstall the tire, then repeat this process for the remaining three wheels; 7. After all four wheels have been drained, check the fluid level in the reservoir under the hood to see if it has reached the lower limit. The reservoir has upper and lower limit markings. If it has reached the lower limit, add new brake fluid as needed; 8. Once the brake fluid change is complete, test the brakes in a relatively safe area.

What are the effects on a car if it doesn't slow down when passing speed bumps?

Frequently passing speed bumps without slowing down can affect the car's suspension, wheels, and interior components. Car Suspension: When a vehicle passes over a speed bump, there is a noticeable impact and a barely perceptible deceleration. Although speed bumps are not completely vertical, they always have some angle. When passing over this angle, the speed bump exerts resistance on the tires, which is directly transmitted to the suspension and then to the car body, resulting in a complete impact. Wheels: This primarily affects mid-to-high-end cars equipped with large-sized wheels and wide, low-profile tires. The sidewall thickness of the tires serves as the first level of shock absorption for the car. The greater the thickness, the more compression it can absorb. If the car doesn't slow down when passing a speed bump, the momentary state is that the tire gets flattened, then hits the wheel rim, and finally returns to the road surface. Each instance of such driving will impact the wheel rim, and over time, it will naturally cause damage to the wheels. Interior Components: This includes electronic configurations, interior panels, CD players, car audio systems, and other visible components. Upon closer inspection, these are all fixed with screws or clips. Frequently passing speed bumps without slowing down can cause rattling noises in the interior components.

Why Shouldn't You Buy a Flood-Damaged Car?

Flood-damaged cars should not be purchased for the following reasons: 1. Electronic system malfunctions: The most water-sensitive components in a car are the electronic systems. Although modern vehicles have waterproofing for electronic circuits, they cannot withstand heavy or prolonged water exposure. If water submerges the engine compartment for an extended period, it can cause wiring corrosion and short circuits, leading to electronic function failures or even spontaneous combustion. 2. Engine failure: Generally, if water has submerged the engine compartment, do not attempt to start the car, as there's no guarantee that the engine hasn't taken in water. Starting it directly could result in immediate engine failure. 3. Transmission issues: The depreciation of flood-damaged cars often stems from transmission problems. Transmissions have vents to release pressure from temperature changes, typically located on the upper part. If water levels rise too high and flood the engine compartment, water may enter the transmission. This can cause slipping, shaking, gear shift jerking, or even necessitate major transmission repairs. 4. Interior mold: Rainwater contains numerous impurities, and a flooded car interior becomes an extremely humid environment prone to mold growth. If the vehicle isn't dried promptly, mold can ruin fabric and leather surfaces while creating unpleasant odors.

What is the purpose of the central locking system in a car?

Central locking system functions are as follows: 1. Central control. When the driver locks the door next to them, all other doors are simultaneously locked. The driver can unlock all doors at once using the door lock switch or open a specific door individually. 2. Speed control. When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening doors by operating the door handles. 3. Individual control. In addition to the driver's door, other doors are equipped with separate spring lock switches that can independently control the opening and locking of individual doors.

What Materials Are Used in Brake Pads?

Here is a detailed introduction to the materials used in brake pads: 1. Semi-metallic materials. These brake pads are still the mainstream products in the market, offering affordable prices and excellent braking performance. However, their shortcomings are also quite evident, including a tendency to generate noise, significant wear on brake discs, and the tendency for brake dust to adhere to the wheel hubs, affecting the wheel's appearance. 2. Ceramic materials. Composed of mineral fibers, glass fibers, and copper elements, ceramic brake pads feature high-temperature resistance, slow thermal decay, no noise, superior braking performance, low wear rates on brake discs, minimal brake dust, and easy cleanup. The downside is their relatively higher price and lower wear resistance compared to metallic brake pads.

What is the classification code for automobile repair invoices?

The automobile repair industry falls under the category of repair and maintenance services in the tax classification code, with the code number 202000. Rules for the classification code of ordinary invoices: The classification code for ordinary invoices (hereinafter referred to as the classification code) consists of 12 Arabic numerals: The first digit represents the code for the State Taxation Bureau or the Local Taxation Bureau, where 1 stands for the State Taxation Bureau, 2 for the Local Taxation Bureau, and 0 for the General Administration; the 2nd, 3rd, 4th, and 5th digits are the regional code (prefecture or city level), based on the unified national administrative region code, with the General Administration being 0000; the 6th and 7th digits are the year code (for example, 2004 is represented as 04); the 8th digit is the unified industry code; the 9th, 10th, 11th, and 12th digits are the refined invoice type codes, which are independently compiled by the State Taxation Bureaus and Local Taxation Bureaus of provinces, autonomous regions, municipalities directly under the central government, and cities specifically designated in the state plan, following the principle of ensuring the uniqueness of each invoice code. Rules for the invoice number: The ordinary invoice number consists of 8 Arabic numerals. If the invoice number resources are insufficient, consideration should be given to combining with the classification code during design, i.e., setting one digit in the 9th, 10th, 11th, or 12th position of the classification code as a batch code; for enterprise-named invoices, one digit can be set separately in the 9th, 10th, 11th, or 12th position of the classification code, or directly in the invoice number by allocating a range of numbers to each enterprise for compilation.
