What Causes Brake Shaking in D Gear?

[VonHadley]

D gear driving in the brake pedal stop when the fundamental causes of shaking: First, the engine power is insufficient. Second, the engine displacement is too small. Third, the throttle carbon deposits. Fourth, the car ignition is not good. Fifth, the normal operation of the engine is blocked. The following is a detailed introduction to the causes of brake shaking: 1. When the brake is pressed in D gear, the car wheels are stationary, and the transmission output shaft, first gear, transmission input shaft, and torque converter turbine rigidly connected to the wheels are all stationary, while the engine is running. The pump wheel and turbine of the engine torque converter are filled with transmission oil between them. 2. For engines with sufficient power, just a little more fuel injection can offset the resistance of the transmission oil, and the driver will not feel shaking in the car. 3. For some engines with insufficient power, such as too small engine displacement, throttle carbon deposits, poor ignition, etc., the engine injects more fuel according to the command, but the additional power generated is not enough to offset the resistance of the transmission oil. In this case, the normal operation of the engine is blocked, and there will be slight shaking, similar to the feeling of dragging the gear while driving.
