Why does the brake become soft again a few days after bleeding the air?

How often should the brake fluid be replaced for the Teana?

Teana brake fluid should be replaced approximately every 2 years or 40,000 kilometers. Brake fluid, also known as hydraulic brake fluid or force oil, is the liquid medium in the hydraulic braking system that transmits braking pressure and is used in vehicles with hydraulic braking systems. Taking the 2021 Teana as an example, its body dimensions are: length 4901mm, width 1850mm, height 1450mm, wheelbase 2825mm, and fuel tank capacity 61.3L. The 2021 Teana is equipped with a 2.0L naturally aspirated engine, with a maximum power of 115kW and a maximum torque of 197Nm, paired with a CVT continuously variable transmission.

What are the operating steps for driving and parking an automatic transmission car?

The operating steps for parking an automatic transmission car are: 1. After the car comes to a complete stop, shift the gear to N (Neutral); 2. Engage the handbrake and then shift the gear to P (Park), after which you can turn off the engine. The starting steps for an automatic transmission car are: 1. Press the brake to slow down until the car stops; 2. Shift the gear from D (Drive) to N (Neutral); 3. Pull the handbrake tightly and turn off the engine; 4. Release the foot brake, but do not turn off the power; 5. Press the foot brake and shift the gear from N (Neutral) to P (Park); 6. Release the foot brake; 7. Turn the key back, turn off the power, and remove the key. The gears of an automatic transmission car are: 1. P (Park) is for parking; 2. R (Reverse) is for reversing; 3. N (Neutral) is the neutral gear; 4. D (Drive) is for driving forward; 5. S (Sport) is the sport mode; 6. L (Low) is the low gear; 7. M (Manual) is the manual gear for semi-automatic cars.

How to Determine if Brake Fluid Needs Replacement?

Methods to determine if brake fluid needs replacement are: 1. Open the brake fluid reservoir cap; if the brake fluid appears cloudy or black, it needs to be replaced; 2. Drive at a normal speed above 40km/h and then brake hard; if the braking distance is significantly longer, replacement is required; 3. If the brakes feel soft or unstable during normal driving, replacement is needed. The reasons for replacing brake fluid are: 1. Moisture or impurities from the air can enter through the reservoir's vent hole, lowering the boiling point of the brake fluid; 2. During prolonged braking, the brake lines can develop vapor lock, leading to reduced braking force or brake failure. The functions of brake fluid are: 1. Brake fluid has a very low freezing point, ensuring good fluidity at low temperatures; 2. Brake fluid has an extremely high boiling point, preventing vapor lock at high temperatures; 3. It does not cause corrosion to metal or rubber.

What is the reason why the van suddenly cannot accelerate?

The reasons why the van suddenly cannot accelerate are: 1. No gasoline; 2. The three-way catalytic converter is blocked, and you can go to a regular enterprise for three-way catalytic cleaning; 3. Insufficient cylinder pressure; 4. During driving, sometimes the car may suddenly fail to accelerate due to bumps. A van is a general term for vehicles that have no protruding engine compartment or luggage compartment at the front and rear, resembling a loaf of bread. Its shape is mainly rectangular, different from sedans, with more internal seats and larger space. The doors are 3 to 5 in total, with one door each for the driver and the front passenger seat. The rear cabin mostly has 1 to 2 sliding side doors, with a few having no sliding side doors. The rear luggage compartment has one door. Compared to sedans, vans can carry more passengers and cargo.
