How to Use Car Coating Agent?

Car coating agent is used as follows: The car coating process involves applying the coating product evenly onto the car paint surface using a specialized spray gun, based on traditional polishing techniques. Then, a specialized sponge is used to spread the liquid solution uniformly over the car body in a spiral motion, followed by wiping with a pure cotton towel. Below is an introduction to the coating process: 1. After car coating, the paint surface exhibits enhanced oxidation resistance, wear resistance, corrosion resistance, and high-temperature resistance. The coating layer is more evenly distributed, finer, harder, and maintains a longer-lasting shine. It transforms the car paint into a continuous surface, increasing the overall paint density. 2. It also provides excellent layering performance, meaning that even after multiple layers, there is no interface between layers, and no 'peeling' phenomenon occurs. When the product is applied to the car paint surface, under natural conditions, the molecular structure undergoes a remarkable transformation due to the action of silicone, changing from a chain structure to a cross-linked network structure between molecular chains, thereby protecting the car paint. This change in molecular structure enhances the product's physical, chemical, and mechanical properties. 3. This results in an ideal effect of long-lasting brightness, a silky touch, and a luxurious appearance, emitting a unique glow similar to sunlight reflecting on water.

How to Identify the Number of Pistons in a Brake Caliper?

There are several circular protrusions on the brake caliper, and these protrusions are the pistons. Multiply the number of protrusions on one side by four to calculate the total number of pistons. Below is an introduction to brake calipers: 1. The brake caliper is part of the automobile braking system and belongs to a type of disc brake. Disc brakes are further divided into solid disc and ventilated disc types, with most modern cars using ventilated disc brakes. Ventilated disc brakes consist of a brake disc, friction pads, brake booster pump, wheel cylinder, and brake caliper. The piston caliper is the device that pushes the friction pads against the brake disc; generally, the number of piston calipers corresponds to the number of friction pads. 2. More friction pads mean a larger friction area, and a larger friction area results in greater friction with the brake disc. Knowing that pistons are equivalent to friction pads, it follows that more pistons indicate better braking performance. 3. The working principle of the braking system is that when the driver presses the brake pedal, brake fluid begins to apply pressure. The brake fluid is transmitted through the pipelines to the pistons of each brake assembly, and the pistons drive the brake caliper to initiate braking. The function of the pistons is to increase the force-bearing area of the brake disc, so more pistons mean a larger friction area on the brake disc.

What does active-eco mean?

active-eco refers to the auto hold function. The following are the specific details about the auto hold function: 1. Advantages: (1) Prevents rolling: In situations requiring short stops such as traffic lights, the system will automatically brake the wheels after the vehicle comes to a stop to prevent rolling; during uphill starts, the system will automatically brake to prevent rolling backward, and after starting, the system will automatically release the wheels for direct forward movement. (2) Automatic locking: Parking and locking do not require pulling the handbrake, as the system will automatically brake the wheels at this time, but this is only available in some models. 2. Disadvantages: (1) Unable to lift the brake: If the auto hold function remains enabled during reversing, the vehicle cannot be controlled to move slowly by lifting the brake, and accidents may occur if the throttle is not well controlled. (2) Jerky feeling: Early versions of the auto hold function had a noticeable jerky feeling during use, resulting in a poor user experience.

Why Does the Vehicle Pull to One Side After Replacing the Steering Gear?

The reasons why a vehicle pulls to one side after replacing the steering gear are as follows: 1. The tread patterns on both sides of the tires are different, or the tread depths are uneven. It is best to use the same type of tires for the entire vehicle, and the tread depths must be the same. If the wear exceeds the limit, the tires must be replaced. 2. Uneven tire pressure on both sides. Uneven tire pressure will cause the tires to become different in size, leading to pulling during rolling. 3. Deformation of the front shock absorber springs or inconsistent damping on both sides. The condition of the shock absorber springs can be judged by pressing or comparing after removal. 4. Failure of the front shock absorbers. When the front shock absorbers fail, the suspension on both sides will be uneven during driving, causing uneven force distribution and resulting in pulling. 5. Excessive wear or abnormal gaps in the vehicle's chassis components. Common parts prone to excessive gaps include the steering tie rod ball joints, control arm bushings, and stabilizer bar bushings. The vehicle should be lifted for a thorough inspection. 6. Poor brake release on one of the tires. 7. Overall deformation of the vehicle frame. If the wheelbase difference on both sides exceeds the maximum allowable range, it can be measured with a tape measure. If it exceeds the range, it must be corrected using a frame straightening machine.

Is ACC Constant Power?

ACC is the constant power switch. Below are the specific introductions to the ignition switch positions in a car: 1. ACC position: At this time, the entire vehicle is powered, and devices such as the radio and lights can operate normally, but the air conditioning cannot be used. Wait for 5 to 10 seconds. 2. LOCK position: The steering wheel is locked, and except for the anti-theft system and small lights, the circuits are completely turned off. 3. ON position: Except for the starter, all other basic equipment can operate normally. 4. START position: Starts the engine. Except for some functions that can operate normally, all other power sources are disconnected. After releasing, the key automatically returns to the ON position.

Which is better, the Prado TX or VX?

VX is better. TX is what we commonly refer to as the base model, which is further divided into versions with and without a sunroof, meaning within the base model there are sub-models with even lower specifications and standard specifications. On the other hand, VX is the high-end model, which is divided into fabric and leather versions, representing the high-spec and top-spec models respectively. Here is some relevant information about the Prado TX and VX: 1. Prado TX model: This can be simply understood as the base model, often referred to as the "bare-bones version." Since the car comes with minimal factory configurations, it is highly suitable for DIY modifications, making it popular among modification enthusiasts. Buyers can purchase it at the lowest price and then customize and upgrade it according to their needs, making it more cost-effective overall compared to higher-end models. This model is mainly found in the Middle Eastern Kuwait version, with spare tire options including under-mounted and rear-mounted types. 2. Prado VX model: Calling the VX a luxury model might be an overstatement, but it is undoubtedly a high-spec version. Firstly, it features the classic rear-mounted spare tire in terms of appearance, and the interior is upgraded with wood-grain trim. Secondly, it is equipped with a liquid crystal dashboard featuring a trip computer, which sets it apart from other versions. The VX model uses a four-link suspension system, offering slightly better handling and off-road capability compared to other versions.
