Automatic transmission oil pumps are categorized into: internal gear pumps, rotor pumps, and vane pumps. An automatic transmission is a gear-shifting device that can automatically change gears based on the vehicle's speed and engine RPM. It consists of a torque converter, planetary gear set, clutches, brakes, oil pump, filter, piping, control valve body, and speed governor. Maintenance methods for automatic transmissions include: 1. Regularly clean the radiator fins to maintain normal water temperature; 2. Periodically clean the engine throttle body and injectors; 3. Change transmission fluid at regular intervals; 4. Use oil of the grade specified by the manufacturer; 5. Add an appropriate amount of transmission fluid; 6. Use high-quality transmission fluid.

What causes the clicking sound when braking in a Bora?

The reasons for the clicking sound when braking in a Bora: 1. The car is new or the brake pads have just been replaced. At this time, the sound is normal because the friction has not yet settled in. It will automatically disappear after driving and breaking in for a few hundred kilometers. 2. The sound occurs after being exposed to rain, as most brake pads are made of iron and will rust when wet. The sound will disappear once the rust is worn off. 3. The brake pads may be installed backward or some screws or parts may be missing. 4. The brake pads may be too small or of low quality. Brake pads, also known as brake linings, are critical safety components in a car's braking system. The effectiveness of all braking depends largely on the brake pads.

Why does the car brake only respond when fully pressed?

When the car brake only responds when fully pressed, it indicates excessive brake pedal free play. There are two main reasons for this phenomenon: 1. If the brake has always performed this way, it may be the result of intentional manufacturer tuning; 2. If a new car's brakes were initially responsive but gradually developed excessive free play over time, this requires attention as it may indicate a brake system malfunction. There are multiple potential causes for increased brake pedal free play, including abnormal brake fluid conditions or worn brake pads. It's recommended to visit a 4S shop for inspection and maintenance to eliminate safety hazards. The car brake system, also known as the automotive braking system, refers to the specialized braking mechanism installed in vehicles to ensure safe driving and improve average speed through technical means.

Where is the Reverse Gear Switch Located in a Car?

The reverse gear switch in a car is located on the transmission housing. For automatic transmissions, there is no separate reverse gear switch; it is integrated into the gear position sensor on the shift shaft. The functions of the car's reverse gear are: 1. Engaging the reverse gear allows the car to move backward, facilitating quick turns and U-turns; 2. Disengaging the reverse gear prevents the car from moving backward; 3. Activating the reverse gear switch turns on the reverse lights and activates the reverse radar. The working principle of the reverse light switch: When the reverse gear is engaged, the mechanical mechanism presses down on the switch contacts, closing the circuit, which turns on the reverse lights and triggers the reverse gear alert sound. When the reverse gear is disengaged, the switch contacts spring back, opening the reverse light circuit again.
