What is the replacement interval for Corolla brake pads?

What are the factors that cause abnormal noise when braking at low speeds?

There are two possible factors that may cause abnormal noise when braking at low speeds: 1. The brake pads have worn to their limit, causing the small metal plate to come into contact with the brake disc. Normally, there is a certain distance between this small metal plate and the brake disc, preventing friction. However, when the brake pads wear down to the limit, the small metal plate contacts the brake disc, and the friction between metal surfaces produces a squeaking sound, alerting the driver to replace the brake pads immediately. Therefore, if there is noise, promptly check the brake pads. 2. The brake pads contain relatively large metal particles, and the noise generated from friction with the brake disc is also due to metal-to-metal contact. This issue has occurred in many vehicles. To eliminate the abnormal noise, the brake pads must be removed and polished. Using sandpaper to grind off a layer of the brake pads will remove the exposed metal particles, preventing further noise.

What are the effects of thin engine oil on the engine?

Thinning engine oil can lead to excessively low oil pressure and cause semi-dry or dry friction between various mating components. Below is relevant information about engines: 1. Introduction: An engine is a machine capable of converting non-mechanical energy into mechanical energy. 2. Classification: Includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. 3. External combustion engines: These refer to engines where fuel is burned outside the engine. 4. Internal combustion engines: Internal combustion engines, or reciprocating piston engines, differ most from external combustion engines in that fuel is burned inside them. There are many types of internal combustion engines, with common gasoline and diesel engines being typical examples.

What is the problem when the EPC light is on and the diesel car cannot accelerate?

EPC light illumination is generally caused by the following reasons: 1. Dirty throttle body: The EPC light mainly illuminates due to a dirty throttle body. This issue can be resolved by cleaning the throttle body and then performing a recalibration. 2. Leakage in the intake system: This causes the engine control unit to detect the problem and illuminate the EPC warning light. Restarting the engine can solve this issue. Additional information: There are only two faults when the EPC light is on: 1. Damaged brake light switch. 2. Improper installation or adjustment of the throttle position sensor, causing the idle switch not to close when the throttle is fully closed, or the idle switch remaining closed when the throttle is partially open.

How to Determine Liability in Accidents Caused by Sudden Turns Without Using Turn Signals?

Failing to use turn signals when turning violates traffic regulations. Below is relevant information about motor vehicles: 1. Definition: Motor vehicles are self-propelled vehicles with two or more wheels that do not require overhead lines or tracks, capable of traveling on roads or off-road surfaces, primarily used for transporting people, goods, or performing specialized tasks. China first saw automobiles in 1901, initially referred to as "automatic vehicles," later abbreviated as "cars" due to being powered by gasoline engines. 2. Classification: Vehicle classification is fundamental in various vehicle standard systems. Different standards have different classification methods, with cross-references between them, each emphasizing different aspects. Only by correctly understanding and grasping the basic concepts and applicable scopes of different classification methods, and clarifying the connotation and extension of specific definitions, can one accurately apply relevant standard clauses in motor vehicle inspection practices, precisely determine vehicle types, and correctly issue inspection conclusions.
