What Causes the Jerking Sensation When Braking?
2 Answers
Braking with a jerking sensation is due to significant wear of brake pads, issues with transmission gear programming, internal contamination and impurities in the transmission, or poor transmission cooling. The specific reasons are as follows: Significant wear of brake pads: Severe wear or aging of the car's brake pads can cause a jerking sensation when braking. It is advisable to replace the brake pads promptly. Transmission gear programming issues: The transmission control system needs to be reprogrammed. Internal contamination and impurities in the transmission: Contamination or impurities inside the transmission can prevent effective regulation of transmission oil pressure, leading to jerking. Poor transmission cooling: This can cause abnormal high temperatures in the transmission, affecting the performance of the transmission oil. If the temperature exceeds 120 degrees Celsius, the rubber sealing materials in the transmission can harden, leading to oil leaks, which in turn affect oil pressure and cause jerking.
I've been driving for over a decade and often experience jerky sensations when braking, which is quite common—it's probably due to uneven brake pad wear. Last time my car shook violently during emergency braking, so I took it to the repair shop. They found the brake pads were nearly worn out, with uneven surfaces. The mechanic also checked the tires and said unbalanced tire pressure could cause unstable braking, especially noticeable as more pronounced bumps at high speeds. It's recommended to schedule regular maintenance, checking brake pad thickness and tire condition at least every six months. If the jerking becomes more frequent, don't ignore it—get it fixed promptly to avoid accidents in emergencies. Also, consider weather effects; if braking feels abnormal on slippery roads, it might be the ABS system working, but that's not the primary cause.
