Volkswagen Lavida's brake pedal cannot be depressed due to reasons such as air leakage in the car's vacuum booster valve. Reasons and solutions for the brake pedal being hard to depress: The car's vacuum booster pump is leaking or malfunctioning. The force applied to depress the brake pedal is amplified by the brake booster pump. If the pump fails, the brake loses its assist, making it difficult to depress; it is necessary to check if the vacuum tube is leaking, and replace it if leakage is found; pressing the brake after the engine is turned off also relates to the brake booster pump. The brake booster pump only continuously generates vacuum when the engine is running. When the engine is off, it relies solely on the residual vacuum assist. The brake pedal might be blocked by the floor mat, preventing it from being depressed, in which case the mat should be removed; a damaged brake booster pump can also prevent the brake from being depressed, requiring replacement of the booster pump. Precautions for the brake pedal: During emergency braking, hold the steering wheel with both hands and avoid single-handed operation. The free travel of the brake pedal directly affects braking time and distance. Therefore, always check if the brake pedal's free travel is appropriate before driving. Braking actions should be swift. If the vehicle skids, release the brake pedal, but quickly correct the steering wheel. Avoid emergency braking during high-speed turns; instead, apply brakes appropriately before turning, maintain straight-line braking as much as possible, and control the turning speed. For braking at medium-low speeds or when shifting gears, press the clutch pedal before the brake pedal. For braking at medium-high speeds or above, press the brake pedal before the clutch pedal.

What brand is Goodyear tire?

Goodyear is a tire brand from the United States, established in 1898. The headquarters of The Goodyear Tire & Rubber Company is located in Akron, Ohio, USA. It is one of the world's largest tire production companies, manufacturing tires, engineered rubber products, and chemical products in multiple factories across various countries. International automotive brands that use Goodyear tires include Rolls-Royce, Mercedes-Benz, BMW, Audi, Volkswagen, General Motors, Ford, Chrysler, and Lexus, among others. The full English name of Goodyear is: Goodyear. The company is committed to the development of new products to meet market demands. Goodyear introduced pneumatic tires in 1899 and obtained a patent for tubeless tires as early as 1903. In 1909, it launched pneumatic tires for airplanes and trucks, and four years later, it introduced the Goodyear "airship" (a helium-filled airship used for promotional and military purposes). In 1917, Goodyear pioneered long-distance truck transportation services, known as "Wingfoot Express." In 1947, it introduced nylon cord tires, followed by polyester cord tires in 1962, which later became the industry production standard. Tires are the only components of a car that come into contact with the ground, affecting the vehicle's driving stability and safety. Tires are rubber products, and rubber products will age over time with prolonged use. Therefore, tires need to be replaced periodically. Generally, tires installed on a car can be used for four years. When purchasing new tires, it is essential to check the production date carefully. Typically, unused tires have a shelf life of three years. The production date of tires is usually marked on the sidewall, represented by four digits, such as 1719, indicating that the tire was produced in the 17th week of 2019. After replacing tires, it is necessary to perform dynamic balancing for each wheel to avoid abnormal vibrations during high-speed driving. Tips for selecting tires: For driving on national highways or expressways: - Braking distance at high speeds: To maximize safety, choose tires with the shortest braking distances on both dry and wet roads. - Comfort: For long-distance travel, select tire products that provide a comfortable ride (with minimal bumps and noise). - Performance: Opt for high-performance tires. For city driving: - Braking distance: To handle various urban driving hazards (such as pedestrians crossing the road), choose tires with the shortest braking distances on both dry and wet roads. - Long mileage life: The tread blocks of tires, which bear the engine power or braking force and contact the road, will deform and slide. Sliding and friction will wear out the tread rubber. Select tires with a longer mileage life. - Fuel economy: Tires with lower rolling resistance can significantly reduce vehicle fuel consumption. For daily use of Goodyear tires, pay attention to the following points: - Regularly inspect the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves gradually become shallow. If the tread wears out, it will lose its drainage and anti-skid functions, significantly reducing the car's performance. Small cracks may pose a risk of tire blowouts during high-speed driving. Additionally, promptly remove pebbles from the grooves. - Park on flat ground as much as possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that may cause rubber deterioration. After parking, drivers should not turn the steering wheel, as this action accelerates tire wear. - Do not splash water for cooling. In hot weather or during high-speed driving, tires are prone to overheating, and tire pressure may increase. In such cases, stop to let the tires cool down. Never release air to reduce pressure or splash water to cool the tires, as this may cause abnormal aging of the tread rubber. - Avoid sudden braking. Try to minimize frequent and hard braking to prevent accelerated tread wear due to dragging between the tires and the ground.

Which Button is the Start-Stop Button?

Start button is located near the gear shift lever. The main positions and principles are as follows. Main position: The symbol for the engine start-stop button is a capital letter A with a circle around it. In most models, the automatic start-stop button is located near the gear shift lever or under the air conditioning panel, while in some models, it is near the ignition switch. Working principle of the start-stop system: When the vehicle stops due to traffic congestion or at an intersection, the driver presses the brake pedal and stops to shift gears. At this point, the start-stop system automatically detects. The wheel speed sensor of the anti-lock braking system shows zero. The electronic battery sensor indicates there is enough energy for the next start. When these three conditions are met, the engine will automatically stop running.

How to Avoid Mistaking the Accelerator for the Brake While Driving?

Develop the habit of placing your right foot on the brake when not in use. Do not sit too close to the steering wheel. Stay focused. Gain a better understanding of the vehicle's structure and performance. Be cautious about the left-right reversal when reversing. Below is an introduction to the accelerator and brake in cars: Accelerator: The accelerator, also known as the throttle, is a control device that regulates engine power. It is part of the car's fuel supply system. By adjusting the pedal pressure, it controls the opening of the engine throttle, manages air intake, and allows the computer to regulate fuel injection, thereby controlling the engine's speed. Brake: The brake, also referred to as the stopping mechanism, is used to halt or reduce the speed of moving vehicles, locomotives, other transport tools, or mechanical equipment.
