What Causes the Abnormal Noise When Braking at Low Speed in a Sedan?

1 Answers

The causes of abnormal noise when braking at low speed in a sedan are as follows: 1. Generally, faults in the caliper, brake disc, or brake pads can produce this abnormal noise. If the noise persists, the first thing to check is whether there is any dragging brake. Poor caliper reset can cause prolonged friction between the disc and the pad, which may produce abnormal noise under certain conditions. 2. If the noise occurs immediately after installing new pads, it may be due to inconsistent sizes between the new pads and the friction blocks, or it could be normal noise during the break-in period of new brake pads. New brake pads and discs require a break-in process. When braking, if it happens to grind against a hard spot on the brake pad (due to the material of the brake pad), this type of noise will occur. 3. When there are sand or gravel particles stuck between the brake pads and the brake disc, this type of noise can also occur. 4. Severe wear of the brake pads can also cause abnormal noise, which is a signal to the owner to replace the brake pads.

Can a vehicle be inspected without the owner's ID card?

Vehicle inspection can be conducted without the owner's ID card. During the inspection, you only need to provide the vehicle license, compulsory traffic accident liability insurance certificate, vehicle and vessel tax payment or tax exemption proof, and motor vehicle safety technical inspection certificate. Below are relevant details: 1. Registration three months in advance: According to Article 49 of the "Motor Vehicle Registration Regulations", the owner of a motor vehicle may apply for an inspection mark at the vehicle management office of the registration place within three months before the expiration of the motor vehicle inspection validity period. 2. Traffic violations must be settled before application: Before applying, the owner of the motor vehicle must settle all traffic safety violations and accidents related to the vehicle.

How much more fuel does using air conditioning in summer consume?

Using air conditioning in summer can account for about 20% of the car engine's power consumption. This means if a car consumes 10 liters of fuel per 100 kilometers, using the air conditioning would increase fuel consumption by approximately 2 liters. The lower the temperature setting, the more fuel it consumes. Below are some related details: 1. Air conditioning operation: The air conditioning compressor requires energy to cool, and since the car's air conditioning compressor is directly driven by the engine, it consumes part of the engine's power, thus increasing fuel consumption. 2. Fixed fuel consumption: For cars with fixed displacement compressors, there's no need to deliberately adjust the temperature or fan speed because the fuel consumption is almost fixed once the air conditioning is turned on, regardless of the temperature setting or fan speed.

Is the ACC adaptive cruise control useful?

ACC adaptive cruise control combines the automatic cruise control system (CCS) and the forward collision warning system (FCWS) of the vehicle. The functions of ACC adaptive cruise control are as follows: 1. Through the feedback signal from the distance sensor: The ACC control unit can judge the road conditions based on the moving speed of nearby vehicles and control the driving status of the vehicle. By sensing the force applied by the driver on the pedal through the feedback-type accelerator pedal, the ACC control unit can decide whether to execute cruise control to reduce driver fatigue. 2. The adaptive cruise control system generally works when the vehicle speed is greater than 25 km/h: When the speed drops below 25 km/h, the driver needs to take manual control. Through system software upgrades, the adaptive cruise control system can achieve the "stop/start" function to cope with frequent stops and starts when driving in urban areas.

Can the wheel size be changed?

Wheel size cannot be changed. Larger wheels with thinner tires do provide less bumpiness on smooth roads, lower fuel consumption, and better handling. However, on roads with mud pits, or lots of stones and steel plates, thinner tires are more prone to blowouts, and driving with larger wheels can be bumpier compared to smaller wheels. The wheel hub is the rotating part of the tire's inner rim connected by pillars to the wheel core, which is the metal component mounted on the axle that supports the tire. It is cylindrical in shape and usually fitted with bearings to reduce friction. It is also known as the rim, steel ring, or tire ring. Common types of wheel hubs include steel rims and aluminum alloy rims.
