Which Wears Out Faster: Front or Rear Brake Pads?

What is the process for repairing paint scratches?

Paint scratch repair processes vary depending on the severity of the scratch, and can be addressed using products like polishing wax, soft wax, liquid wax, toothpaste, or touch-up paint pens. Here are the specific details: Minor scratches: Wipe the area twice with a damp towel, then apply wax directly. Even non-abrasive polishing wax works well. Visible scratches: First clean the paint surface, then use a soft towel dipped in toothpaste to rub back and forth, followed by wiping with a clean towel. After cleaning, apply wax and polish immediately, preferably using liquid wax or soft wax. Repeat if necessary. Scratches reaching the primer: After cleaning, use a touch-up paint pen (scratch repair pen) to cover the metal completely, let it dry, then apply wax and polish. Large areas with exposed primer: In such cases, repainting is recommended. If insurance considerations delay repairs, perform rust prevention (using toothpaste) first, then apply a layer of wax to repair as much as possible. Coarse wax with the largest abrasive particles or liquid wax can be used.

What to Do If There Are Large Gaps After Replacing the Windshield?

Large gaps after replacing the windshield may be caused by incomplete removal of the original adhesive. It is necessary to seal the wider gaps between the glass and rubber strips with sealing strips. Precautions after windshield replacement: Do not wash the car within three days after replacing the windshield, and remove the tape fixing the windshield position after three days; try to avoid driving on excessively bumpy roads, and avoid sudden braking and rapid acceleration; do not insert parking permits or other cards into the gap between the windshield and the dashboard; do not drive on highways, and keep the maximum speed below 80 km/h; avoid applying window film within seven days. Precautions for windshield repair: Before repairing the car glass, thoroughly clean all dirt from the car glass. Carefully selected cleaners and related cleaning products are good choices. Turn off the defroster heating after 5-10 minutes of use, otherwise it may cause the rear windshield to crack.

What is the fuel consumption of the Mistra 1.8 automatic transmission?

The comprehensive fuel consumption of the Mistra 1.8L is 5.3L/100km. There are currently 3 models of the Mistra 1.8L available for sale: the CVT-GLS Leading Edition, CVT-GLX Elite Edition, and CVT-LUX Premium Edition, all with a comprehensive fuel consumption of 5.3L/100km. The above figures are based on the NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 6.0-8.6L/100km. The specific factors affecting a car's fuel consumption are as follows: Car weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L engine and a weight of about 1.2 tons has a fuel consumption of approximately 7.5 liters (calculated under full load), while an SUV weighing about 1.5 tons consumes around 8.5 liters. Different weights result in varying fuel consumption. Drag coefficient: Higher drag coefficients increase fuel consumption during driving. Cars with better aerodynamics have lower drag coefficients, leading to lower fuel consumption. Economical RPM: During driving, the engine has an optimal torque output point where fuel consumption is minimized. Generally, small-displacement cars reach this point at about 70 km/h, while larger-displacement cars reach it at around 100 km/h. Maintaining speed within this economical RPM range results in the least fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light can increase fuel consumption.

What is the brake pad reset method for the 2020 BMW 325Li?

BMW 325 brake reset involves long-pressing the black button at the bottom left of the dashboard until the oil or brake pad indicator appears. Below is relevant information about BMW brakes: Method for BMW brake reset: Close the car door and turn on the key; long-press the black button at the bottom left of the dashboard until the oil or brake pad indicator appears; when a triangle symbol appears in the middle, do not release the button; when the brake pad indicator appears, release the button and long-press it again, "RESET" or "Reset" will be displayed, then release and long-press once more to complete the reset. In car maintenance, brakes are a very important aspect. Working principle of car brake pads: The working principle of brakes mainly comes from friction, using the friction between the brake pads and the brake disc (drum) and between the tires and the ground to convert the kinetic energy of the moving vehicle into heat energy after friction, thereby stopping the car. A good and efficient brake system must provide stable, sufficient, and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities.

Does Rain Affect the Vehicle After Crystal Coating?

Some crystal coatings contain nano-maintenance agents, which are minimally affected by rain. Below is relevant information about crystal coating: 1. Introduction to Crystal Coating: Crystal coating is akin to cleansing the face with a facial cleanser, exfoliating, and then applying lotion and sunscreen, topped off with a 'mask,' thereby forming a dense protective layer. The 'crystal' is a material obtained by grinding and manipulating glass atoms and molecules to below 100 nanometers. 2. Benefits of Crystal Coating: Strong Water Resistance. The surface after nano-crystal coating exhibits superior water resistance. When water falls on the car's surface, it beads up like on a lotus leaf, preventing the formation of water stains and protecting the paint from contamination. Heat Resistance. After nano-crystal coating, similar to glass crystals, it effectively reflects sunlight and radiation during hot summer days, thereby resisting high temperatures and preventing damage to the car's paint from heat.

Can Tires Be Recycled?

Tires can be recycled. Used tires are generally collected by auto parts markets. Tire vendors purchase various waste tires from tire repair shops, recycling stations, and drivers. After centralized collection and sorting, these tires are sold to upstream dealers locally or in other regions based on demand. The upstream dealers process them into usable tires, which are then sold back to tire repair shops or drivers. Tire retreading is a technology that refurbishes worn or otherwise damaged tires through repair and reprocessing, restoring their usability. Waste tire oil refining technology involves heating and pressurizing discarded tires to extract fuel oil. However, if simple and inexpensive equipment is used, this process can easily cause secondary pollution. The tire rubber powder reclaimed rubber technology first uses waste tire rubber powder equipment to crush tires into 20~30 mesh rubber powder. The rubber powder then undergoes a desulfurization process to soften and restore plasticity, allowing it to be reprocessed into various rubber products. If the desulfurization technology is substandard, it can also lead to pollution.
