What Causes Abnormalities in the Braking System?
2 Answers
Abnormalities in the braking system can manifest in the following symptoms and causes: 1. Symptom: The brake pedal does not rise and lacks resistance when pressed. Cause: Check for insufficient brake fluid; leaks in the brake wheel cylinders, pipelines, or joints; or damage to components in the master or wheel cylinders. 2. Symptom: Poor braking effect even when the pedal is fully depressed; no improvement with continuous braking, and the pedal gradually rises. Cause: Air in the braking system. 3. Symptom: Continuous braking causes the pedal to return higher, with improved braking effect. Cause: Excessive gap between the friction pads and brake drum. 4. Symptom: Continuous braking causes the pedal position to rise, with a sinking sensation. Cause: Oil leakage. 5. Symptom: The pedal position is low and cannot rise. Cause: Blockage in the master cylinder. Solution for braking system faults: It is recommended to promptly visit a 4S shop for inspection and repair.
I've been driving for almost twenty years and have experienced several instances of the braking system acting up. The most common issue is when the brake pads wear too thin, emitting a sharp squealing sound with every press—it's downright alarming. Another scenario is when the brake fluid is low or has aged and deteriorated, turning black, making the pedal feel spongy and ineffective. Air getting into the lines is also frequent, especially if the fluid change isn't done properly, leaving the brakes feeling like stepping on cotton. Last time I had my car serviced, the mechanic mentioned that ABS system failures can also cause unusual noises or warning lights. These things all require regular checks; it's recommended to visit a repair shop at least once a year to measure brake pad thickness and replace old fluid. Don't wait until something goes wrong to regret it—safety is paramount, and maintenance is more convenient than ever now.
