The symptom of brake pads not retracting is a noticeable increase in vehicle resistance. Here are the specific details: 1. Function of the brake wheel cylinder: The brake wheel cylinder is an essential component of the braking system. Its primary function is to push the brake pads against the brake drum, causing friction that reduces speed or brings the vehicle to a stop. 2. Reasons for the brake wheel cylinder not retracting: Even without pressing the brake pedal, there is a significant feeling of increased resistance in the vehicle. In severe cases, there may be noise or even wheel lock-up. The main causes of this phenomenon are usually prolonged failure to replace the brake fluid, leading to internal rust in the brake wheel cylinder, or poor precision of the caliper, causing the piston not to retract properly. It could also be due to blockage in the brake wheel cylinder pipeline, requiring inspection and repair.

Are Car Bumper Guards Useful?

Car bumper guards are useful. They are attached to the protruding parts of the car's corners and are made of rubber or natural rubber, serving as exterior body decorations. The functions of bumper guards include: 1. Adding body lines and a dynamic look, resistant to fading, and serving a decorative purpose; 2. Protecting the car's sides from scratches or impacts by foreign objects; 3. Reducing the risk of car door collisions, as they possess a certain degree of elasticity. The installation method for door bumper guards is: 1. Open the door and locate the protruding areas prone to collisions; 2. Rinse the car with water and dry the area where the bumper guard will be attached with a towel; 3. Slowly peel off the adhesive backing; 4. Align and press gently to ensure the strip fully adheres to the car's surface; 5. Avoid washing the car within 48 hours after installation to prevent the adhesive from getting wet and losing its stickiness.

How to Adjust the Headlights on the Verano?

Verano headlight adjustment method: Open the engine hood, and you will find two white hexagonal plastic adjustment knobs at the rear of the headlights. The knob closer to the rear headlight mounting bracket is for height adjustment. Use a hexagonal adjustment rod or screwdriver to rotate the knob - clockwise rotation raises the beam height, while counterclockwise rotation lowers it. The Verano is a compact car under the Buick brand, with body dimensions of 4718mm in length, 1802mm in width, and 1466mm in height, and a wheelbase of 2700mm. In terms of exterior design, the Verano features a bold front fascia with the brand's signature design language and dynamic, flowing body lines. For the interior, the Verano adopts the same family hallmark 360-degree wraparound cockpit design as the Envision, with a sporty dual-dial instrument cluster and a centrally located 4.2-inch color trip computer display that provides various vehicle information.

What Causes the Noise When Shifting to Reverse Gear and Braking?

It is normal to hear a noise when shifting to reverse gear and braking, as this sound is caused by the friction between the brake pads and the brake disc. The vehicle's braking system mainly consists of a vacuum booster pump, master brake cylinder, wheel brake cylinder, brake pads, and brake disc. When the driver presses the brake pedal, the vacuum booster pump provides assistance, making it easier for the driver to press the pedal. The vacuum booster pump only operates when the engine is running. After the engine is turned off, the vacuum booster pump cannot provide assistance. The vacuum booster pump is located in the engine compartment. After opening the engine hood, you can see a black metal disc below the windshield on the driver's side. This disc is the vacuum booster pump. In front of the vacuum booster pump is the master brake cylinder, which has a reservoir for holding brake fluid. The operation of the vehicle's braking system relies on brake fluid. When the brake pedal is pressed, the master brake cylinder uses the brake fluid to push the pistons in the wheel brake cylinders, which then press the brake pads against the brake disc, allowing the vehicle to decelerate. Brake fluid needs to be replaced regularly because it is a liquid that easily absorbs moisture. Absorbed moisture can reduce braking force and increase stopping distance.

What is the fuel tank capacity of the 8th-generation Civic?

The fuel tank capacity of the 8th-generation Civic is 47 liters, as officially announced. Owners of the 8th-generation Civic can also check this information on the vehicle's configuration sheet. The 8th-generation Civic requires 92-octane gasoline, with a fuel consumption of 5.0 to 6.4L per 100 kilometers. A full tank can cover a distance of 734 to 940 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space between the safety limit and the tank opening, designed to accommodate 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.
