If the brake pedal is hard to press, it may be due to a leak or failure in the car's brake booster pump. Regular maintenance of the brake system is essential during normal vehicle use. Issues such as excessive impurities in the brake master cylinder, poor sealing, leakage in the brake master or wheel cylinders, failure of the vacuum booster pump, or overloading can all lead to brake failure. In addition to regular inspections and timely replacement of worn friction components, the brake system should also undergo proper periodic maintenance: 1. Clean the surfaces of brake friction components and their cooling channels with solvent-based cleaners; 2. Apply long-lasting protective agents to the rubber dust boots of the brake wheel cylinders and areas prone to rust; 3. Apply long-lasting lubricants to the contact surfaces between the tire rims and the car hubs; 4. Use high-temperature and impact-resistant lubricants on areas such as the back of the brake friction components and noise-damping shims.

What are the disadvantages of a body-on-frame structure?

The following are the disadvantages of a body-on-frame structure: 1. The body-on-frame structure is relatively bulky, heavy, and tall, typically used in trucks, buses, and off-road vehicles. Some high-end sedans also use it because it offers better stability and safety. 2. The body and frame are rigidly connected, which can lead to less smooth driving on highways and may cause vibrations. 3. In dangerous situations (such as a rollover), the heavy chassis can pose a fatal threat to the relatively weaker body (a unibody structure does not encounter this issue as its body is integrated). Additional information: The advantage of a body-on-frame structure is that it has an independent frame, providing higher chassis strength and better resistance to bumps. Additionally, uneven forces on the four wheels are borne by the frame and not transmitted to the body. This is why SUVs and off-road vehicles often use this structure.

How to Deal with Scratched Paint on a White Car?

The methods to deal with scratched paint on a white car are: 1. Use scratch wax to gently polish the scratched area, which can simply fix the paint issue. 2. Purchase a touch-up pen that matches the car's color and apply it to the scratch to cover the unsightly damage. 3. Use nail polish that is similar in color or transparent to fill and repair the scratched area. 4. Visit a professional paint shop for repair. If a small piece of paint is scratched off, first determine whether it is the original paint or just the surface layer. If only the surface paint is scratched, you can use a "nano scratch repair cloth"—minor scratches can be restored with a simple wipe. Whether the scratches are minor or deep, a touch-up pen can be used for repair.
