Why does the Prado brake pump frequently activate?
2 Answers
The frequent activation of the Prado brake pump may be due to a lack of necessary maintenance of the braking system, severe overloading of the vehicle, or improper operation leading to mechanical failure. Other reasons: Excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, dirty brake fluid, or mixing different types of brake fluid can all lead to brake failure. Introduction to braking: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, and other transportation tools or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force.
I've been driving a Prado for over ten years and once encountered an issue where the brake pump kept activating. It turned out that air had entered the braking system, causing the ABS to frequently misjudge slip and engage. This might have been due to incomplete fluid replacement during maintenance or a minor leak in the hose, leading to unstable pressure in the vacuum booster pump. While driving, I noticed the brake pedal feel had deteriorated, which posed a significant safety hazard, especially on slippery rainy days. I immediately went to the 4S shop for inspection. They cleaned the wheel speed sensors, added brake fluid, and bled the system, which resolved the issue. It's important to regularly check the fluid level and address any issues promptly to avoid major problems. Remember, regular maintenance is also crucial.
