Is It Normal for an Automatic Car to Jerk When Braking?
2 Answers
Automatic cars experiencing a jerking sensation when braking is a normal occurrence. Here is a detailed introduction to automatic cars: 1. Overview: Automatic cars generally refer to vehicles that use an automatic transmission (AT) to regulate speed. While driving, the automatic transmission's control system automatically selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and gear shifting. 2. Other Information: Automatic cars typically use a hydraulic transmission device to replace the mechanical clutch of manual cars, hence there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward.
Having driven automatic transmission cars for so many years, I've gotten used to the slight jolt when braking, especially when slowing down suddenly after high-speed driving, it often feels like the car is being tugged. This is usually a normal response from the transmission downshifting as the engine RPM adjusts. However, if the jolt is too strong or the car jerks every time you brake, then something might be wrong—it could be warped brake discs or worn brake pads. I once experienced this myself; the brakes felt particularly harsh during city traffic jams, and upon inspection, it turned out the brake caliper was stuck. Replacing the part fixed the issue. Remember, regular maintenance is crucial—don't wait for small issues to become big ones. Additionally, when the ABS system kicks in to prevent skidding, there might be a jolt, but this is part of its safety function. If it happens occasionally and mildly, it's usually fine, but if it occurs frequently, it's best to get it diagnosed at a professional auto repair shop. Maintaining your braking system well can significantly improve overall driving comfort.
