The functions of a car brake wheel cylinder are: 1. After pressing the brake pedal, the master cylinder generates thrust to push hydraulic fluid to the wheel cylinder. The piston inside the wheel cylinder moves under hydraulic pressure to push the brake pads. 2. It consists of a brake master cylinder and a brake fluid reservoir. One side connects to the brake pedal, while the other connects to the brake fluid lines. The brake master cylinder stores brake fluid and has outlet and inlet ports. When braking, the outlet port opens while the inlet port closes. 3. Under the pressure of the cylinder piston, brake fluid is squeezed out through the lines to flow to each wheel cylinder for braking function. When releasing the brake pedal, the outlet port of the master cylinder closes while the inlet port opens, allowing brake fluid to flow back from each wheel cylinder to the master cylinder, returning to the original state.

What does 'GPF is full, please increase speed' mean?

GPF is full, please increase speed refers to the gasoline particulate filter being clogged. GPF is a ceramic filter installed in the gasoline engine's emission system, which captures particulate emissions before they enter the atmosphere. The main function of the GPF gasoline particulate filter is to reduce particulates. When the indicator light in the car comes on, it means that the particulates accumulated in the GPF have reached a level that requires cleaning. If the indicator light is green, the situation is relatively better, and you can drive more on highways to allow the GPF to self-clean the deposited particulates. If the light is yellow, the solution is to increase the exhaust temperature to burn off the carbon deposits.
