The most common reasons a INFINITI Q70L shakes when braking are bad brake rotors, bad brake pads, or a bad wheel bearing.
  • Brake Rotor: A warped or worn brake rotor can cause vibrations during braking and reduced stopping power.
  • Brake Pad: A worn or damaged brake pad can lead to reduced braking efficiency and increased stopping distances.
  • Old Brake Fluid: Old brake fluid can absorb moisture over time, leading to reduced braking performance and potential corrosion within the brake system.

Troubleshooting Shaking When Braking in an INFINITI Q70L

When experiencing shaking while braking in your INFINITI Q70L, begin by inspecting the brake pads and rotors, as worn components are often the primary culprits. Look for uneven wear or significant thickness reduction in the pads, and check the rotors for warping or scoring. If these components appear to be in good condition, examine the suspension system for any loose or damaged parts, as these can also contribute to instability during braking. Next, assess the brake calipers for any signs of damage or malfunction, which could affect braking performance. Additionally, inspect the wheel bearings for wear, as faulty bearings can lead to vibrations. If you have replaced or repaired any of these components and the issue persists, consider the quality of the brake pads you are using, as inferior products may not perform adequately. By following this diagnostic approach, you can systematically identify and address the source of the shaking, ensuring a safer and smoother driving experience.

What Causes Shaking When Braking in an INFINITI Q70L?

When your INFINITI Q70L experiences shaking during braking, it can be both alarming and indicative of underlying issues that need attention. One of the most common problems is worn tires, which can lead to uneven contact with the road surface, exacerbating vibrations. Additionally, warped brake rotors are a frequent culprit; they can cause the brake pads to engage unevenly, resulting in noticeable shaking. Bad wheel alignment is another factor that can contribute to this issue, as misaligned wheels can create instability during braking. If your tires are out of balance, this can also lead to vibrations, particularly at higher speeds. Furthermore, a loose or damaged wheel bearing may cause excessive lateral runout, leading to vibrations that can affect braking performance. Other potential issues include old or worn brake pads, sticky brake calipers, and suspension problems, all of which can contribute to the shaking sensation. To effectively address these concerns, it is essential to conduct a thorough inspection of your vehicle, focusing on these key areas, and consider consulting a qualified mechanic for a comprehensive assessment and necessary repairs.

Why is My INFINITI Q70L Shaking When Braking?

When your INFINITI Q70L shakes while braking, it’s crucial to address the issue promptly to avoid serious safety risks and potential damage to your vehicle. The shaking can often be attributed to warped rotors, which may occur due to excessive heat or hard braking. If left unaddressed, warped rotors can lead to uneven wear on your brake pads, further exacerbating the problem and compromising your braking efficiency. Additionally, worn or poor-quality brake pads can contribute to this unsettling experience, making it essential to invest in high-quality replacements. Furthermore, alignment issues can also manifest as shaking during braking, indicating that your tires may need realignment to ensure proper handling and safety. Ignoring these symptoms not only jeopardizes your safety on the road but can also lead to more extensive and costly repairs down the line. Therefore, it’s imperative to diagnose and resolve the cause of the shaking as soon as possible to maintain the performance and safety of your INFINITI Q70L.
