How Many Kilometers Should Brake Discs Be Replaced?

Brake discs should be replaced every 60,000 to 70,000 kilometers. Here is some relevant information about brake discs: 1. Function: Brake discs are used for braking, with the braking force coming from the brake caliper. Typically, the brake caliper is fixed to the inner side where the brake piston pump is located, while the outer side has a clamp-like structure. The inner brake pad is fixed to the piston pump, and the outer brake pad is fixed to the outer part of the caliper. 2. Structure: Disc brake rotors are divided into solid discs (single-piece discs) and ventilated discs (two-piece discs). While driving, air flows through the ventilation channels to achieve cooling, which is much more effective than solid discs in terms of heat dissipation.

What Causes the Brake Pump of an Electric Vehicle Not to Rebound?

Possible reasons for the brake pump of an electric vehicle not rebounding are as follows: 1. Possible Causes: Piston rust, due to water ingress or corrosion, causing the vehicle's piston to rust and preventing it from rebounding normally. The rectangular rubber sealing ring aging, which may expand, deform, and lose elasticity after aging. Check whether the vehicle's brake line routing is normal. 2. Precautions: If the brake is found not to rebound during vehicle use, the driver should first release the throttle pedal to allow the vehicle to gradually slow down until it comes to a stop. Then, adjust the brake line inside the brake system; if the brake line is too loose, the driver needs to tighten it slightly. If the brake line is too tight, it is recommended that the driver seek professional assistance promptly for handling.

What Causes the Warning Light to Illuminate?

The reasons for the warning light illuminating are as follows: 1. Sensor issues: When the water temperature, crankshaft position, air flow, intake temperature, or oxygen sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data; 2. Maintenance problems: Irregular maintenance and poor driving habits can increase the burden on engine operation; 3. Fuel quality issues: The fuel added to the car has a specific grade, and failure to add it as required can cause engine wear; 4. Poor combustion of the air-fuel mixture: This can lead to engine carbon buildup or knocking issues, which are detected by the engine's oxygen sensor; 5. False alarms: These can occur due to impacts while driving, tampering with certain engine connectors, or temporary ECU signal interruptions.

Does Uneven Tire Pressure Have an Impact?

Tire pressure imbalance does have an impact. Here's relevant information: 1. Effects of uneven tire pressure: If a significant difference in tire pressure is detected, immediate measures must be taken to adjust the pressure. This is because excessive tire pressure deviation causes varying rolling resistance among tires, especially when the pressure differs between tires on the same axle. This can lead to vehicle pulling to one side during driving, compromising driving safety. 2. Precautions: If the tire pressure deviation is relatively minor and doesn't cause noticeable changes during driving, it may not significantly affect vehicle operation. However, it's crucial to continuously monitor tire pressure changes. Most modern vehicles are equipped with tire pressure monitoring systems that can track tire temperature and pressure in real-time. When pressure changes are detected, the system will issue an alert to notify the driver.

How to Identify a Used Car?

Identifying a used car can be done through the following methods: 1. Check the left and right shoulders: Drive the vehicle onto a flat surface and stand 3 meters in front of it to observe if the left and right shoulders of the vehicle are at the same height. If they are not, it indicates that the vehicle's frame has been repaired or the suspension and shock absorbers have not been fixed. 2. Inspect the engine hood: Check if the gaps on both sides of the engine hood are even. A significant difference may suggest a possibility of collision, and such vehicles should be avoided if possible. 3. Examine external components: Inspect the headlights for signs of aging, check the edge gaps for symmetry, observe if the tire tread patterns are worn or aged, ensure the glass sealing strips are neat, and verify the presence of logos on the windows to confirm if all logos are from the same brand.

How to Identify the Front and Back of a Tire?

Tire identification methods for front and back are as follows: 1. "OUTSIDE" and "INSIDE" markings: Generally, the sidewall of the tire will have "OUTSIDE" (outer) and "INSIDE" (inner) markings indicating the front and back. When installing the tire, simply ensure the side marked "OUTSIDE" faces outward and the side marked "INSIDE" faces inward. 2. Arrow markings: Some tires may have rotation direction arrows on the sidewall. For such tires, installation should not only follow the rotation direction indicated by the arrow but also ensure the side with the arrow faces outward. 3. Production date and other information: For convenience, the side with the tire production date, size specifications, and other information is usually placed outward, while the side with no or minimal markings faces inward.
