What Causes the Brake Pads of Golf 7 to Make Abnormal Noises?

Golf 7 brake pad abnormal noise causes: 1. Brake pads are too hard. 2. Brake pads are worn down to the skeleton. 3. Brake discs or drums are excessively worn. 4. Brake calipers are rusted. 5. Handbrake cable malfunction. 6. Brake pads do not retract properly. Possible scenarios and solutions for abnormal noises: 1. If it's a dull sound, it's mostly an issue with the brake caliper, such as worn sliding pins or detached spring plates. 2. If it's a squealing sound, there could be multiple issues, including problems with the caliper, brake disc, or brake pads. 3. If the noise persists, first check for dragging brakes; poor caliper retraction can cause prolonged friction between the disc and pads, leading to abnormal noises under certain conditions. Then, inspect whether there are any foreign objects stuck between the pads and disc. For new pads, check if the brake disc has grooves, as localized friction can cause abnormal noises. If the disc is fine, consider whether the brake pads are too hard or if the noise-reducing shims are installed incorrectly.

Does a New Car Need Water Added?

A newly purchased car does not require water to be added. Regular passenger cars do not need water; instead, the radiator is filled with coolant, not water. Simply check if there is sufficient coolant in the radiator. If the coolant level is low, you can directly add coolant until it reaches the midpoint between the upper and lower level marks. Precautions during the break-in period of a new car include: 1. Maintain smooth starts, avoid sudden acceleration, and do not let the engine RPM get too high; 2. Ensure the coolant temperature reaches at least 50 degrees Celsius before starting, begin in a low gear, and shift to a higher gear after driving 1 kilometer; 3. Shift gears promptly while driving, avoid prolonged use of a single gear, and do not drive at low speeds in high gears or at high speeds in low gears; 4. Choose good road conditions to avoid excessive vibration and impact, and disengage the clutch before braking; 5. Use high-quality fuel and engine oil, and avoid using engine wear-resistant additives.

What Are the Pros and Cons of Car Waxing?

Waxing is a traditional car care procedure. The advantages and disadvantages of car waxing are as follows: Advantages: 1. Polishing effect: Polishing is the most basic function of car wax. Vehicles that have been waxed can improve the brightness of their surface, restoring the body to its original luster. 2. Waterproof and acid rain protection: Due to the protection of car wax, the amount of water droplets adhering to the car body is significantly reduced. 3. High-temperature resistance: Cars are exposed to high temperatures and sunlight year-round, which can cause the paint to age and fade. The film formed by waxing can effectively reflect light, preventing the paint or base coat from aging and fading due to incident light. 4. Anti-static effect: Static electricity in cars comes from interior fabric and friction between airborne dust and the car body during driving. Static electricity often causes many inconveniences, and car wax effectively blocks dust from the car body, reducing static electricity generation. 5. UV protection: The UV protection effect of car wax works in parallel with its high-temperature resistance. Due to the characteristics of UV light, it easily refracts into the paint surface. UV-protective car wax fully considers this characteristic, minimizing damage to the car's surface. 6. Polishing and buffing effect: When shallow scratches appear on the paint surface, polishing wax can be used without harming the paint. Disadvantages: 1. Product damage: There are many types of car wax on the market with varying performance and effects. Choosing the wrong wax or using inferior products can damage the paint. 2. Paint surface wear: Precisely because of the polishing effect, improper operation or excessive polishing can easily wear the paint surface. 3. Dirt adhesion: Under high temperatures and prolonged engine operation, the wax can melt and easily attract dust and stains.

How to Use the 4WD System on the Prado 2700?

The Prado 2700 features three 4WD modes: H4F with the center differential unlocked, H4L (high-speed 4WD) with the center differential locked, and L4L (low-speed 4WD) with the center differential locked. Below is an introduction to these three 4WD modes: 1. Use H4F for urban roads and generally for dirt roads as well. 2. H4L is only used for extremely muddy or difficult terrain. 3. L4L is used when stuck or climbing steep slopes. When switching between H4L and L4L modes, note the following: 1. For manual transmission models: Depress the clutch pedal and stop the vehicle or maintain a speed below 5 km/h. 2. For automatic transmission models: Stop the vehicle, apply the brakes, and shift the transmission to 'N' first. This function can be used in combination with the transmission's L gear for extreme off-road or recovery situations. 3. The four transmission gears in full-time 4WD mode (H4F): D gear for daily driving, 3 gear for overtaking and acceleration, 2 gear for aggressive overtaking, hill climbing, off-road use, and acceleration, and L gear for high-altitude hill climbing, recovery, extreme off-road, and water fording.
