Brakes feeling soft and then hard intermittently is because the vacuum booster pump is not yet operational at that moment. The methods for brake maintenance are as follows: 1. Avoid sudden braking: Emergency braking significantly damages the brake pads, so it's important to brake gently during normal driving or use the technique of pumping the brakes, which causes less wear on the brake pads. 2. Reduce the frequency of braking: Develop a good habit of minimizing brake usage during normal driving. You can first use engine braking to reduce speed before applying the brakes for further deceleration or stopping. Downshifting can also be used more frequently to slow down. 3. Regularly inspect the brake pads: After the vehicle has traveled 40,000 kilometers or been in use for over 2 years, the brake pads may be significantly worn. It's essential to conduct thorough periodic inspections to check if the thickness of the brake pads has reached the minimum limit. If it's close to the limit, the brake pads should be replaced. Under normal driving conditions, inspect the brake pads every 5,000 kilometers, checking not only the remaining thickness but also the wear condition of the pads, whether the wear is even on both sides, and if they retract smoothly, among other factors.

What is the fuel tank capacity of the 2021 Corolla?

The 2021 Corolla has a total of 12 models. Among them, the 1.8L models have a fuel tank capacity of 43 liters, while the 1.2T and 1.5L models both have a fuel tank capacity of 50 liters. This data is officially released. The 2021 Corolla uses 92-octane fuel. The 1.8L models have a fuel consumption of 4-4.1L per 100 kilometers, allowing a driving range of 1048-1075km on a full tank. The 1.2T and 1.5L models have a fuel consumption of 5.2-5.6L per 100 kilometers, with a driving range of 892-961km on a full tank. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is usually done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is recommended to refuel when only 2 segments remain to avoid running out of fuel mid-journey. In actual refueling situations, the amount of fuel may exceed the marked capacity. This is because the manufacturer's specified fuel tank capacity is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is reserved to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity.
