There are two main reasons for replacing brake fluid: 1. Brake fluid directly affects braking performance. Due to weather and external factors, brake fluid absorbs moisture and impurities over time, leading to deterioration. This results in insufficient braking force, creating safety hazards. 2. Contaminated brake fluid causes wear to sealing components in the braking system, shortening the lifespan of brake parts, making regular replacement essential. Additional information: How brake fluid works 1. When the brake pedal is depressed, the hydraulic system pressurizes the brake fluid. 2. The pressurized fluid from the master cylinder is distributed to all four wheel cylinders. 3. The pistons in wheel cylinders are actuated by the pressurized fluid, forcing brake pads to clamp the rotors.

Function: ECD is an energy conversion device, standing for Economy and Energy Conservation. The ECD light on indicates the energy-saving mode is activated. The energy-saving mode will display in the bar frame based on the driver's throttle pressure, aiming to cultivate good driving habits.

Does the Tayron GTE have a three-electric warranty?

The Tayron GTE has a three-electric warranty. For new energy vehicles, the three-electric components refer to the motor, power battery, and electronic control system, which can be considered the core components of a new energy vehicle. Motor: The motor is the power source of a new energy vehicle. Based on structure and principle, motors can be divided into three types: DC drive, permanent magnet synchronous, and AC induction, each with different characteristics. Power Battery: The power battery is the energy source for driving the motor. Currently, power batteries are mainly distinguished by their cathode and anode materials, including lithium cobalt oxide, ternary lithium, lithium manganese oxide, and lithium iron phosphate. Ternary lithium and lithium iron phosphate batteries are more commonly used in new energy vehicles. Electronic Control System: The electronic control system is actually a general term, which can be further divided into the vehicle control system, motor control system, and battery management system.
