What Causes Brake Discs to Turn Yellow?

Brake discs turning yellow is a normal phenomenon and has no impact on the vehicle or braking performance. Some discs may not discolor because the discoloration wears off after driving or the car is parked in an underground garage and not exposed to rain. In fact, brake disc rust is a normal occurrence and is not necessarily related to quality. Since brake discs are made of steel and lack anti-rust protection due to frequent friction, rust can appear after being parked in humid weather for a few days or exposed to rain. Below is an introduction to automotive braking systems: 1. Introduction to Braking: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. The general principle of braking involves fixing a wheel or disc on the machine's high-speed shaft and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. A braking device is a mechanical deceleration device, also known as a retarder. 2. Classification of Brakes: Drum brakes (advantages and disadvantages), disc brakes, etc.

What is the ground clearance of the GAC Toyota Levin?

The minimum ground clearance of the Toyota Levin is 105mm. The minimum ground clearance refers to the distance between the lowest point of the vehicle (excluding the wheels) and the supporting surface when the car is fully loaded and stationary, which is used to characterize the vehicle's ability to pass obstacles such as stones and stumps without collision. Below is some relevant information about the Toyota Levin: 1. The all-new Levin comes standard with 8 airbags and multiple electronic-assisted active safety systems, including ABS anti-lock braking system, VSC vehicle stability control system, HAC hill-start assist system, TRC traction control system, and more. In addition, it is equipped with a PM2.5 purification device, which is the first time Toyota has introduced this feature, allowing real-time monitoring of PM2.5 concentration inside the car. 2. In terms of power, the all-new Levin is equipped with a 1.2T inline 4-cylinder direct-injection turbocharged engine. By reducing internal engine friction, improving the intake pipe, and modifying the intake manifold, the engine's combustion efficiency is enhanced, and acceleration feel is improved. Paired with a simulated 10-speed S-CVT transmission, its 0-100 km/h acceleration performance even surpasses that of ordinary 1.8L models, effectively preventing carbon buildup and ensuring high reliability and durability.
