What's the situation when the car's brakes are too hard to stop the vehicle?

Reasons for hard-to-press brakes: Braking before engine shutdown: The vehicle's braking system operates at maximum efficiency when the engine is running, with the brake booster being the key component that amplifies the force applied to the pedal. When the engine is off, the brake booster ceases to function, typically depleting its residual vacuum force after about three pedal presses. Thus, the sensation of hard brakes is essentially due to the lack of assistance from the brake booster. Solution: In this scenario, simply restart the engine and firmly press the brake pedal again. Once the engine is running, the brake booster will resume operation, and the brake pedal will return to normal. Brake booster malfunction: If the car's brake booster is leaking or malfunctioning, and you haven't pressed the brake pedal after turning off the engine, or you notice the brake pedal is unusually hard to press while driving, it's likely due to a faulty brake booster, possibly from a leaking or clogged vacuum tube. Solution: If this issue is detected before driving, it's safest to avoid driving and have the vehicle inspected at a repair shop immediately. If the problem arises while driving, remain calm, prioritize slowing down to a stop, and attempt multiple pedal presses to see if braking can be restored. Applying strong pressure often helps engage the braking force.

Should You Downshift When Overtaking with a Manual Transmission?

Whether to downshift when overtaking with a manual transmission depends on the car's power and speed during the overtaking maneuver. If the speed is already high, there's no need to downshift—simply press the accelerator. However, if the RPM is low and the speed is slow, downshifting is necessary for the quickest and safest acceleration to overtake. When overtaking, it's important to observe the dynamics of the vehicle being overtaken by turning your head, choose the right moment to overtake, accelerate and merge into the adjacent lane, pass the vehicle in a straight line until a safe distance is achieved, and then merge back into the original lane. Understand your car's acceleration performance before overtaking: The driver should fully understand the car's acceleration capabilities before attempting to overtake. Ensure that the horn, turn signals, and headlights are functioning properly. Choose a straight, wide road with good visibility, no obstacles on either side, and no oncoming traffic within 150 meters ahead. Overtaking should only be done under safe conditions, avoiding reckless maneuvers regardless of subjective or objective conditions. Increase speed before overtaking: Before overtaking, increase your speed and approach the left side of the vehicle you're overtaking to reduce the distance between you. Turn on the left turn signal and honk the horn (or flash the headlights at night) to notify the vehicle ahead. Once you confirm that the vehicle ahead is yielding or signaling to yield, slightly steer to the left while maintaining a safe lateral distance from the vehicle being overtaken.

What does the M gear in a manual-automatic transmission mean?

M gear is the manual mode of a manual-automatic transmission. In this gear, shifting can be done like in manual transmission vehicles, with upshifting at high speeds and downshifting at low speeds. When using the manual shifting mode, you need to switch the gear lever to the M position. While driving, you can directly shift into the M gear. Shifting can be done by simply moving the gear lever, using the paddle shifters on the steering wheel, or pressing the shift buttons. When climbing a long steep slope, the driver can switch to manual mode and engage the 1st gear. This keeps the vehicle in a low gear, preventing frequent gear changes, which makes climbing more powerful and also protects the transmission. When descending a long slope, the driver should also use manual mode to keep the transmission in a low gear, which helps control the speed without prolonged braking, avoiding overheating and reduced braking performance. Advantages of manual-automatic vehicles: Faster braking and stopping: When the vehicle is traveling at high speed and requires urgent braking, using manual downshifting can slow the vehicle down as quickly as possible. This is easier to master and operate in manual mode, allowing the vehicle to stop faster. Faster cornering: Normally, when taking a corner, the driver first applies the brakes to slow down before entering the corner, then accelerates when exiting. By switching to manual-automatic mode before entering the corner and downshifting to use engine braking to control speed, the driver can smoothly and safely exit the corner with just a light press of the accelerator. Faster overtaking: When overtaking, switching from D gear to manual mode and performing two consecutive downshifts increases the engine speed and torque. With a light press of the accelerator, the vehicle can overtake easily and quickly.

What are the criteria for replacing car tires?

The criteria for replacing car tires are when the tire rubber has aged to the critical point of deterioration, the tire has worn down to the wear indicator, the tire sidewall is bulging, the tread is deformed or bulging, the tire has a leak that cannot be repaired, the tire produces unexplained noises while driving, exhibits uneven wear, misalignment, or abnormal wear. Lifespan of car tires: The lifespan of car tires is generally 3-5 years or a mileage of 60,000-80,000 kilometers under normal driving conditions. However, depending on the driver's habits, road conditions, and parking environment, the lifespan of car tires may vary. Hazards of using expired tires: Expired tires have aged rubber, making them prone to cracking, reduced flexibility, and severely diminished heat dissipation. Not only does comfort drastically decrease, but acceleration and braking performance also suffer significantly. High-speed driving carries the risk of a blowout, so expired tires must be replaced even if they haven't reached the wear indicator. Method for replacing tires: Park the car, turn off the engine, and engage the handbrake to prevent sliding. Loosen the bolts in a diagonal pattern, lift the vehicle to a certain height, remove the bolts and take off the old tire, install the new tire and tighten the anti-theft bolts in a diagonal pattern, lower the vehicle and tighten the bolts and nuts. Precautions for tire replacement: Choose tires of the same specifications, replace the valve stem at the same time, pay attention to the installation direction and inflation, check the tire pressure, perform a wheel alignment after replacement, slightly loosen the fixing bolts before using a jack to lift part of the vehicle when removing the tire, and choose tires with guaranteed quality.

Can a truck be driven with the ABS light constantly on?

ABS malfunction light is on, it is recommended not to continue driving, because the ABS light on indicates a fault in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it impossible for the driver to slow down or adjust the vehicle's trajectory, posing significant safety hazards. There are various states in which the ABS light may be on, with different causes and solutions for each state, as detailed below: State 1: ABS malfunction light stays on (most common). Cause 1: The ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed and the wheel's slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt off the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections in the system wiring or poor contact in the ABS relay, leading to system malfunction. Solution: Check the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently turns on, but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, and the ABS indicator light turns off; the ABS system's power supply voltage is too low, possibly due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (such as voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wiring connector; ABS computer malfunction. Solution: Loosen the grounding screw of the hydraulic valve body, then retighten it, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light turns on during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant difference between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently turns on. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down with a finger until it bottoms out, then release the brake pedal to complete the self-setting position; replace the brake light switch.
