What Causes Steering Wheel Vibration When Lightly Pressing the Brakes?
2 Answers
Steering wheel vibration when lightly pressing the brakes is caused by: uneven wear between the brake discs and brake pads, or jagged wear on the brake discs, which generates resonance transmitted to the steering wheel through the steering gear. The only solution to this issue is to replace the brake discs and brake pads with new ones. The braking system is crucial and requires regular inspection and replacement of brake fluid. Over time, friction between the brake pads and discs produces metal shavings that need periodic cleaning. During normal braking, the brake discs generate significant heat due to friction as the vehicle slows down, leading to high temperatures. Compared to brake pads, brake discs wear more slowly, but after prolonged use, they will show signs of wear. If the brake disc surface becomes uneven or the thickness falls below standard, it can severely impact braking performance over time.
I also experienced steering wheel vibration when lightly applying the brakes, which I noticed while driving in rainy conditions. The possible causes include warped or uneven brake rotors - this typically occurs after frequent hard braking when the rotors heat unevenly and cool down deformed. Another reason could be uneven brake pad wear, causing vibrations to transfer to the steering wheel during contact. Tire balance issues might also be relevant; if the wheel rims are deformed or tires severely worn, braking vibrations become more pronounced. I recommend visiting a repair shop to inspect the braking system first. They can use specialized tools to measure rotor surface flatness and should also check for any looseness in the suspension and steering systems. Don't underestimate this issue - continuing to drive could accelerate component wear and even compromise driving safety. During regular maintenance, always consult technicians about such conditions.
