What Does Brake Dragging Mean?
2 Answers
Brake dragging refers to dragging the brakes. Explanation of brake dragging: Brake dragging means lightly pressing the brake when passing through a deceleration zone, allowing the system to detect the deceleration action. The purpose of brake dragging is to let the system sense the deceleration action when passing through areas where speed reduction is required. Never press the clutch while dragging the brakes, as this will result in coasting in neutral. Situations requiring brake dragging include: when driving straight through an intersection, be sure to drag the brakes. Reduce speed and drag the brakes when passing schools or bus stops. For right turns, also release the accelerator and drag the brakes, then accelerate after the vehicle straightens. Braking techniques: When following another vehicle, ensure a safe distance and apply the brakes gently. The key technique is to press the brake pedal softly, maintain braking force, and then adjust the pressure based on the leading vehicle's speed. When you notice the leading vehicle braking (brake lights on), place your foot on the brake pedal and apply even pressure to smoothly decelerate until matching the leading vehicle's speed. Maintain the brake pedal position and observe the leading vehicle's speed changes to adjust braking force. If the leading vehicle stops decelerating, slowly release the brake pedal and accelerate to maintain the same speed. Uphill braking techniques are similar to those on flat roads, but due to the vehicle's weight aiding deceleration, less braking force is needed. Brake more gently uphill than on flat roads, but release the brake pedal faster to prevent excessive speed loss.
I've encountered the issue of brake drag several times. It basically means the brakes don't fully release while driving, causing the wheels to drag as if being held back by an invisible hand. Common causes include rusted/seized brake calipers, air bubbles in the hydraulic system preventing complete release, or the parking brake not being fully disengaged. Typical symptoms include: the car feels unusually hard to drive, sluggish acceleration, significantly increased fuel consumption (e.g., from 8L/100km to 10L/100km), wheel hubs becoming hot to the touch or even smoking, and loud abnormal noises. Immediate inspection and repair are necessary to prevent brake disc damage and reduce accident risks. My recommendation is to have a professional mechanic examine the calipers and hydraulic system - usually just needs cleaning and lubrication.
