What Does Brake Pad Wear Mean?

2 Answers

Brake pad wear refers to the gradual wearing down of the friction blocks on a car's brake pads due to frequent braking during use. As a result, the braking effectiveness diminishes over time. If not replaced promptly, it can lead to a complete loss of braking performance, compromising driving safety. Steps to replace brake pads: 1. Open the engine compartment and check the brake fluid level to prevent overflow during replacement. 2. Remove the wheel where the brake is located. 3. Unscrew the bolts of the brake caliper and take out the old brake pads. 4. Install new brake pads, tighten the guide bolts, and complete the replacement. Brake pad materials include: 1. Asbestos, cellulose, sintered glass. 2. Carbon fiber friction materials. 3. Powder metallurgy friction materials. 4. Semi-metallic friction materials.

Brake pad wear refers to the gradual thinning of those two small pads in the braking system during use. Having driven for over a decade, I've encountered this situation several times. The brake pads make contact with the wheels, and each time you press the brake, friction is generated to slow down the car. However, excessive friction gradually wears away the material, which is called wear. If the wear becomes too severe, you may notice louder noises when braking or a softer pedal feel, at which point the braking effectiveness is significantly reduced. In emergency situations, the stopping distance increases, which can be quite dangerous. It's best to have regular inspections, such as checking every 10,000 to 20,000 kilometers driven, or listening for any squeaking sounds yourself. Replacing the pads is a minor issue, but neglecting repairs could lead to major accidents. In short, this is normal wear and tear—just address it promptly.

How often are new private cars inspected?

New private cars are inspected every two years, and the inspection does not require on-site testing. According to the "Opinions on Strengthening and Improving Motor Vehicle Inspection Work", all newly manufactured passenger cars and other small and mini passenger vehicles are exempt from safety technical inspections before motor vehicle registration. Below is more relevant information: 1. Relevant regulations: Starting from September 1, 2014, a trial exemption system was implemented for non-commercial passenger cars and other small and mini passenger vehicles within 6 years of registration. For biennial periodic inspections, vehicle owners can directly apply for inspection labels from the traffic management department of the public security authority by providing compulsory traffic accident liability insurance certificates and proof of vehicle and vessel tax payment or exemption, without undergoing safety technical inspections at inspection agencies. 2. "Motor Vehicle Registration Regulations": Article 49 states that motor vehicle owners can apply for inspection qualification labels from the local vehicle management office within three months before the expiration of the motor vehicle inspection validity period. Before applying, the vehicle owner must resolve all traffic safety violations and accidents related to the vehicle. When applying, the owner must fill out an application form and submit the vehicle license, compulsory traffic accident liability insurance certificate, proof of vehicle and vessel tax payment or exemption, and motor vehicle safety technical inspection qualification certificate. The vehicle management office should verify the motor vehicle, review the submitted proofs and certificates, and issue the inspection qualification label within one day of acceptance.

Where is the diagnostic port located on the Citroen C4?

The diagnostic interface of the Citroen C4 is located behind the trim panel under the steering wheel. You can see the OBD port by opening the trim panel. OBD, which stands for "On-Board Diagnostics" in Chinese, is a system that continuously monitors the engine's operating conditions and the working status of the exhaust after-treatment system. It will immediately issue a warning if it detects any condition that may cause excessive emissions. Below is some relevant information about OBD: 1. How it works: The OBD device monitors multiple systems and components, including the engine, catalytic converter, particulate trap, oxygen sensors, emission control systems, fuel system, EGR, etc. OBD connects to the Electronic Control Unit (ECU) through various emission-related component information. The ECU has the capability to detect and analyze faults related to emissions. When an emission fault occurs, the ECU records the fault information and related codes, and alerts the driver through the malfunction indicator lamp. The ECU ensures access to and processing of fault information through a standard data interface. 2. Challenges faced by OBD: The introduction of OBD technology requires improvements in the following related supporting conditions: fuel quality, vehicle maintenance skills, consistency of related components, improvement in driver skills, enhancement of OBD technology itself, and support from various sectors of society. For a certain period, China's adoption of OBD technology involves a process of introduction, adaptation, and assimilation. This is because OBD technology poses a challenge and an opportunity for improvement in the automotive industry chain.

Does Water in the Charcoal Canister Affect the Car?

Water in the charcoal canister can easily cause damage to the car's engine and affect the vehicle's service life. Below is a detailed introduction about the car's charcoal canister: 1. Overview: The charcoal canister is generally installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank is often filled with vapor at room temperature. The function of the fuel evaporation emission control system is to introduce the vapor into combustion and prevent it from volatilizing into the atmosphere. The activated charcoal canister storage device plays a crucial role in this process. 2. Others: After the engine is turned off, gasoline vapor mixes with fresh air in the canister and is stored in the activated charcoal canister. When the engine is started, the solenoid valve installed between the activated charcoal canister and the intake manifold opens, and the gasoline vapor in the activated charcoal canister is drawn into the cylinder by clean air under the vacuum of the intake pipe to participate in combustion.

Is It Advisable to Buy a 2-Year-Old Stock Car?

2-year-old stock cars can be purchased as they offer significant price advantages and generally maintain their performance. Below are key points about stock cars: 1. Definition of Stock Cars: There is no industry-wide standard, but typically, new cars are sold within 1-2 months after leaving the factory. Therefore, most industry professionals consider cars stored for over 3 months as stock cars. 2. Issues with Stock Cars: Compared to regularly used second-hand cars, stock cars are more prone to component aging due to prolonged inactivity, especially vulnerable parts like batteries, plastic components, rubber parts, and interior wiring.

Does running the air conditioner without driving affect the car?

Turning on the air conditioner after starting the engine without driving has almost no impact on the car. However, keeping the engine in an idle state for a long time can lead to increased carbon deposits in the engine and higher fuel consumption. Carbon deposits occur because the combustible mixture in the engine cannot burn completely, and they can cause significant harm to the engine. Here are more related details: Precautions: 1. It is true that the air conditioning compressor is driven by the engine, but the air blown by the blower is powered by the battery. The car may not charge the battery during idle, and excessive power consumption by the blower could result in long-term battery depletion. Taking the car for a high-speed drive occasionally helps recharge the battery and maintain its health. 2. The direct airflow without air conditioning utilizes the engine's waste heat, which is the principle behind the car's warm air in winter, and does not involve the air conditioning refrigerant. A handy tip: If the car's coolant temperature is too high and doesn't drop, it indicates insufficient cooling by the front radiator fan. In an emergency, turning on the warm air from the air conditioner can provide an additional cooling channel. 3. Prolonged idling with the air conditioner on will certainly have negative effects. It increases fuel consumption and engine carbon deposits, with the greatest harm being to humans. In a stationary state, the air inside the car doesn't circulate properly. Closing the windows can make people feel comfortable enough to fall asleep, leading to unconscious carbon monoxide poisoning and oxygen deprivation.
