Is Brake Maintenance Necessary?

Yes, it is necessary. The braking system is one of the most critical components of a vehicle and operates in extremely harsh conditions. If this system malfunctions, it can pose a danger at any time. Therefore, regular inspection and maintenance of the braking system are essential. Some common issues that may arise with the braking system include: abnormal braking noises, pulling to one side, insufficient braking force, a soft brake pedal, and abnormal brake wear. Here are several methods for maintaining your car's braking system: 1. Use solvent-based cleaners to clean the surfaces of the brake friction components and their cooling channels. Avoid cleaners containing lubricating ingredients to prevent damage to rubber parts. 2. Apply high-temperature-resistant (above 600°C) and impact-resistant lubricants to the moving parts of the brake friction components. This helps with lubrication, auxiliary heat dissipation, and filling, preventing uneven wear. Avoid using lubricants like grease that cannot withstand high temperatures, as they may have adverse effects once burned off. 3. Apply high-temperature-resistant (above 600°C) and impact-resistant lubricants to the backside of the brake friction components, such as noise-damping shims, to eliminate brake squealing. 4. Use high-temperature-resistant (above 120°C) lubricants on the brake caliper guide pins to ensure proper brake response time. Avoid using lubricants like grease that cannot withstand high temperatures.

I've been driving for over a decade, and I truly believe brake maintenance is something you can't afford to skip. Once on a rainy highway, I almost rear-ended someone, and later found deep grooves worn into the brake discs during inspection. Now I make it a rule to get a comprehensive check every two years. The focus is on brake pad thickness, lubricating guide pins, and replacing brake fluid. Brake pads must be replaced if they're under 4mm, and brake fluid absorbs moisture which lowers its boiling point and compromises safety. If you do a lot of mountain driving, inspections should be even more frequent. Crunch the numbers—a few hundred bucks for maintenance is nothing compared to medical bills after an accident. A friend of mine skimped on this, ignored the screeching noise when turning, and ended up with seized calipers, costing over 3,000 to fix.

What is the function of the automatic transmission P gear?

Used when parking. When you arrive at your destination or need to park for an extended period, shift the gear lever into this position. P gear: "Parking" means "to park" and in a car, it refers to the parking gear. Note: Always ensure the vehicle is completely stopped before shifting into P gear. Shifting into P gear before the vehicle has fully stopped can cause mechanical damage to the automatic transmission. When in P gear, the wheels are mechanically locked, preventing the vehicle from moving forward or backward. Therefore, always engage P gear when parking on a slope. Additionally, during brief stops (such as at traffic lights), it's best not to shift into P gear to avoid severe damage to the entire transmission if rear-ended. Besides, automatic transmission cars also have other gear positions marked with letters like N, R, S, D, L, and M. Below is a detailed introduction: N gear: "Neutral" means "neutral" and is also called the neutral gear. When waiting at traffic lights, you can shift into N gear, but to prevent the vehicle from rolling, you need to press the brake pedal. If the waiting time is long, it's recommended to engage the handbrake, allowing your foot to rest off the brake pedal. Many drivers mistakenly believe that coasting in N gear downhill or at high speeds saves fuel. This is a serious misconception; it not only doesn't save fuel but can also damage the transmission. R gear: "Reverse" means "to reverse" and in a car, it's called the reverse gear, used when backing up. To reverse, press the safety button on the gear lever and shift into R gear. However, it's crucial to ensure the vehicle is completely stopped before performing this operation to avoid severe damage to the transmission. S gear: "Sport" means "sport" and the S gear function in a car allows for instant acceleration. In sport mode, the engine runs at higher RPMs, which can also help remove carbon deposits. Many automatic transmission cars come with an S gear. In sport mode, the transmission can shift freely, but the shift timing is delayed, keeping the engine at high RPMs for longer periods. This allows the car to maintain low gear and high RPM for extended periods, providing greater torque output and acceleration, but at the cost of higher fuel consumption. D gear: "Drive" means "to drive" and in a car, it refers to the forward gear. Shifting into this gear and pressing the accelerator allows the car to move. In this gear, the transmission automatically shifts based on speed and throttle input. You can stay in D gear while waiting at traffic lights by pressing the brake pedal. If the wait is short, this is fine, but prolonged idling in D gear can raise the transmission fluid temperature and degrade the fluid. L gear: "Low" means "low speed" and in a car, it refers to the low-speed forward gear. When in L gear, the transmission operates only in low gear (equivalent to manual transmission's 1st gear) and does not automatically shift to other gears based on speed. This gear is typically used when climbing or descending steep slopes. In low gear, the drive wheels output greater torque, providing sufficient power to climb steep slopes. Prolonged braking can overheat the brake pads and reduce braking effectiveness, which is dangerous on long descents or steep slopes. Shifting into L gear uses the engine's low RPM to control the vehicle's movement, eliminating the need for constant braking. M gear: M gear is the manual mode. After shifting into M gear, the driver can manually control the transmission's upshifts and downshifts. This can be used when climbing or descending slopes or when needing to overtake quickly.

How to Deal with Mold and Mildew Growing on the Steering Wheel?

Car steering wheels are usually covered with a layer of leather, which can be treated with anti-mold and antibacterial agents. Mold growth is often caused by a damp steering wheel and an overall humid interior environment. You can clean it with water, dry it with a cloth, and then ventilate the car by opening the windows.

How to Turn Off the Camry Alarm?

Owners can locate the car's fuse box according to the prompts, find the alarm fuse, and then use professional tools to remove the alarm fuse. Owners can use the key to open the driver or passenger door, wait for a few minutes, and generally, the alarm will automatically stop sounding. Open the car engine hood, locate the car alarm according to the car's operation manual, and directly turn off the alarm following the operation guide.

What are the correct driving steps for a CR-V automatic transmission vehicle?

First, you need to press the brake pedal in the vehicle's cockpit; otherwise, the vehicle cannot be started. Then, press the button below the steering wheel, which is the one-touch start button, to start the vehicle's engine. Next, toggle the electronic parking brake button located at the center console to release the vehicle's brake. After that, shift the gear lever to D (Drive) mode, and finally, release the brake pedal to allow the vehicle to move normally.
