What Causes the Lack of Braking Force in the First Half of the Brake Pedal Travel?

The lack of braking force in the first half of the brake pedal travel can be attributed to insufficient brake fluid pressure (due to low fluid level in the master cylinder, ruptured brake lines, leaking pipe connections, or clogged fluid passages), air in the brake system, excessive free play in the brake pedal or excessive brake clearance, poor contact or severe wear of the brake shoe friction lining, or oil contamination. Other causes include wear or scoring of the master cylinder, wheel cylinder pistons, or cylinder bores, as well as aging or damage to the rubber seals. Below is more relevant information: Vehicle Braking: Vehicle braking refers to the act of stopping the vehicle, where braking force is the maximum rolling friction achievable. This is because friction drops suddenly when rolling transitions to sliding—maximum rolling friction is greater than sliding friction. This is why vehicles are equipped with anti-lock braking systems (ABS). Braking performance is one of the primary characteristics of a vehicle, directly related to driving safety.

Where is the 9-digit engine number located?

Locations to check the engine model number: exterior surface of the engine block, vehicle registration certificate, motor vehicle registration document, purchase invoice, factory certificate of compliance, operating license for commercial vehicles, vehicle purchase tax payment certificate, public security authority registration records, vehicle insurance card, and the actual engine (usually on the engine nameplate). Engine numbers are like a person's ID number, representing each vehicle and storing crucial information about it. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the engine's attributes. It is used to indicate information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are required to display the professional manufacturer's name, model, and production number. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and multiple engines can share the same model. The engine number, however, refers to the production serial number of the engine, with each engine having a unique number that cannot be duplicated. Composition of the vehicle engine number: Prefix: Includes the product series code, generation symbol, and regional or corporate code. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standardization authority. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. Suffix: Comprises symbols for structural features and usage characteristics. Tail section: Distinguishing symbol. When differentiation is required due to improvements or other reasons within the same product series, the manufacturer selects an appropriate symbol. The suffix and tail sections may be separated by a hyphen (-).

What does Castrol Edge FE mean?

Castrol FE engine oil refers to the latest titanium fluid formulation, which does not fall under the category of engine oil grades. For example, SN and others indicate the oil grade, while the titanium fluid series of oils all belong to the SN grade, so there is no conflict between the two. Here is more related information: Castrol FE engine oil: Castrol Edge uses advanced titanium fluid strengthening technology and is the brand's excellent high-end engine lubricant. Infused with liquid titanium formulation, it has a unique oil film self-adaptation capability, effectively reducing direct metal-to-metal contact under various driving conditions, thereby reducing friction loss and ensuring the engine performs excellently. Engine oil grades: API on engine oil stands for the American Petroleum Institute, divided into SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN grades, with the grade increasing in order. SN grade is currently the highest grade of engine oil. SJ is the standard of the 1990s, SL is the standard of 2001, SM is the standard of 2004, and SN is the standard of 2010.

What is the difference between OEM and aftermarket catalytic converters?

The difference between OEM and aftermarket catalytic converters depends on the specific product in question. It is not necessarily true that aftermarket catalytic converters are inferior to OEM ones, as some aftermarket products can perform just as well. However, most car owners lack in-depth knowledge about automotive parts, making it difficult for them to determine whether the catalytic converter they purchase meets the required standards. If a car owner is not familiar with vehicle structures, it is advisable to replace the catalytic converter with an OEM part at a 4S dealership. The quality of the catalytic converter directly affects whether the vehicle can pass annual inspections. If a catalytic converter is found to be damaged, it should be promptly repaired or replaced at a service center. Below is more relevant information: Replacing with an aftermarket catalytic converter: In fact, there is no issue with replacing it with a qualified aftermarket catalytic converter. However, the automotive parts market is a mixed bag, and without professional knowledge, it is best to opt for an OEM catalytic converter from a 4S dealership. Generally, OEM catalytic converters offer better compatibility than aftermarket ones, effectively catalyzing harmful substances in exhaust emissions. Using a substandard catalytic converter can not only lead to excessive emissions but also increase exhaust backpressure, negatively impacting the engine's power output.
