What are the reasons for ineffective braking in a hydraulic braking system?

There are four main reasons for ineffective braking in a hydraulic braking system, which are: 1. Loose connection between the brake pedal and the master cylinder. 2. No fluid or severe lack of fluid in the brake fluid reservoir. 3. Brake pipe fracture or oil leakage. 4. Rupture of the master cylinder piston cup. To ensure the uninterrupted operation of the hydraulic brake, it is necessary to regularly maintain it. There are five maintenance measures, which are: 1. Frequently add lubricant to the electromagnetic brake. 2. Regularly check the length of the armature stroke. During the operation of the brake, wear on the braking surface will occur, increasing the length of the armature stroke. When the armature stroke length does not reach the normal value, it should be adjusted to maintain the minimum gap between the braking surface and the rotating disc. 3. If the worn braking surface is replaced, the minimum gap between the braking surface and the rotating disc should be readjusted appropriately. 4. Frequently check the tightness of the bolts. 5. Regularly inspect the mechanical wear condition of the movable parts and remove dust, debris, and dirt from the surface of the electromagnet components.
I've been working in auto repair for decades, and hydraulic brake system failures are often directly related to brake fluid issues. Leaking brake fluid or low fluid levels can directly affect pressure transmission—a simple check of the reservoir can confirm if this is the cause. Air bubbles entering the system will make the brake pedal feel spongy, requiring timely bleeding; otherwise, stopping the car will feel sluggish. Severe wear on brake pads or discs can also lead to insufficient friction, necessitating replacement. If the master cylinder fails, the entire system shuts down, requiring part replacement. And if the brake booster malfunctions, pressing the brake pedal feels as strenuous as pulling an ox cart. I always remind people to check fluid levels monthly and have a professional perform a comprehensive inspection annually to prevent issues before they arise. After all, hydraulic brakes are critical to driving safety—no minor risk should be overlooked. Safety comes first.
Last month my car had a brake failure - the pedal felt like stepping on air, and I almost couldn't stop at an intersection. When I took it to the repair shop, the mechanic diagnosed air in the hydraulic system, likely caused by moisture absorption in aging fluid creating bubbles. After bleeding the system and replacing the fluid, it returned to normal. Another time the brake warning light came on, which turned out to be a small crack in the brake line causing fluid leakage and low fluid level leading to brake failure. From my personal experience, most problems stem from small details like air intrusion or fluid leaks, but the consequences can be serious. Make it a habit to regularly check if the fluid reservoir level is above the midpoint. If you notice a soft pedal or delayed response, get it inspected immediately. Don't cut corners or delay repairs - this practice helped me avoid a potential rear-end collision. Safety should never be taken lightly.
As a car enthusiast, I often discuss issues related to hydraulic brake failure. First, check if the brake fluid is low—low fluid levels often indicate leaks or evaporation, and timely refilling can prevent trouble. Air in the system can make the pedal feel spongy, but bleeding the brakes with the right tools will solve this. Worn brake pads need regular replacement to ensure strong friction performance. If the master cylinder fails and pressure doesn’t build, it must be repaired or replaced. Contaminated fluid is a hidden problem—old fluid absorbs moisture, corroding the lines and affecting performance. I recommend changing the fluid every two years to maintain cleanliness—simple maintenance can prevent major disasters. Driving may be cool, but safety always comes first.
