What are the causes of ineffective car braking?
3 Answers
The causes of ineffective braking are as follows: 1. Excessive free travel of the brake pedal; 2. Insufficient or no oil in the brake master cylinder reservoir; 3. Deteriorated brake fluid or excessive buildup of deposits inside the pipeline; 4. Air entering the brake pipeline or vaporization of brake fluid causing air resistance; 5. Leakage of oil from the brake master cylinder, wheel cylinder, pipeline, or pipe joints; 6. Excessive wear of the pistons and cylinder barrels in the brake master cylinder or wheel cylinder; 7. Aging or wear of the rubber cups in the brake master cylinder or wheel cylinder leading to poor sealing; 8. Blockage of the oil inlet hole of the brake master cylinder or the vent hole of the reservoir; 9. Poor sealing of the outlet valve or return valve of the brake master cylinder; insufficient preload of the piston return spring; blockage of the small through hole at the front end of the piston; 10. Improper clearance between the brake drum and brake shoe; too small contact area between the brake drum and brake shoe; poor quality or oil contamination of the brake shoe; loose rivets of the brake shoe; groove wear or out-of-roundness of the brake drum, deformation during braking; 11. Loose or detached vacuum pipe joints of the vacuum booster or power booster, cracked pipelines; ruptured diaphragm or poor sealing of the sealing ring; poor sealing of the one-way valve or control valve; excessive wear of the auxiliary cylinder piston or rubber cup; poor sealing of the one-way ball valve.
When the brakes on the car fail, it's usually one of the most frustrating problems I encounter while driving my old car. The main reason is that the brake pads wear out over time, and if they're not thick enough, they can't grip the brake disc properly, leading to longer stopping distances. Or, the brake disc might rust or warp, causing the steering wheel to vibrate when you press the pedal. It's also essential to check the brake fluid—if the level is low or air gets in, the pressure drops, which is very dangerous. Aging pipes leaking fluid or a malfunctioning ABS system sensor can also cause brake failure. A friend of mine once nearly had an accident on the highway, all because they didn't regularly inspect and replace parts. For safety, always have a mechanic check the thickness of the brake system during maintenance and replace parts promptly to drive with peace of mind. Don't wait until an accident happens to regret it!
As a seasoned long-distance driver, I've found that brake failure is often related to daily maintenance. After prolonged driving, brake pads can wear out completely or brake fluid can become contaminated, lowering its boiling point and making it prone to failure during emergency braking. Insufficient tire pressure or shallow tread patterns can also reduce grip, leading to longer braking distances. In hot weather, brake discs are prone to overheating and warping. I still remember one time when my brakes felt mushy while driving uphill—it turned out the calipers were clogged with dirt and lacked lubrication. I recommend checking the dashboard warning lights before driving. If you notice the brake pedal feels lighter than usual, head to a professional shop immediately to replace the parts—don't skimp on small expenses and risk major problems. Make it a habit to get your braking system inspected every six months to extend component lifespan and ensure your family's safety.
