How to Deal with Brake Air Leakage?
2 Answers
Solution for air leakage in the air brake master cylinder: Disassemble and clean it, check if the air shut-off valve is damaged, and if it's intact, apply some grease and reassemble it properly. Below are some brake maintenance measures: 1. Replacement: Under normal driving conditions, inspect the brake shoes every 5,000 kilometers. Not only should you check the remaining thickness, but also the wear condition of the shoes, whether both sides are wearing evenly, and whether they retract smoothly. Any abnormal conditions must be addressed immediately. 2. Use specialized tools for braking: When replacing brake shoes, always use specialized tools to push the brake caliper piston back. Do not use other pry bars to force it back, as this can easily bend the guide screws of the brake caliper, causing the brake pads to seize.
I'm the type of driver who prioritizes safety above all else, so whenever I notice brake air leakage, I immediately pull over and turn off the engine—it's no trivial matter. Brake air leakage usually indicates an issue with the brake booster system, such as a ruptured vacuum hose or loose connection, and the hissing sound means I can't brake properly. My first response is to stay calm and repeatedly press the brake pedal to check if it feels unusually stiff; if it does, the vacuum booster might have failed. Then, I quickly inspect the brake fluid reservoir to see if the level is too low while carefully listening for the source of the leak. If I can't pinpoint the problem, I call for a tow truck right away to take the car to a professional repair shop—never risking driving further, as it concerns everyone's safety. Additionally, I make it a habit to check the maintenance manual before long trips, and regularly inspecting brake hoses for aging helps prevent issues beforehand. Brakes are a lifeline; delaying repairs can easily lead to accidents. I'd rather spend time waiting for professionals to handle it properly.
