The most common reasons a Audi 90 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 Audi 90

When experiencing shaking while braking in your Audi 90, start by inspecting the brake rotors, as they are often the primary culprit. Look for signs of warping or damage, which can be identified by uneven wear or visible grooves. If the rotors appear compromised, replacing them is essential for restoring smooth braking. Next, check the brake pads for wear and ensure they are properly bedded in according to the manufacturer's guidelines. This bedding process is crucial, as it helps prevent uneven deposits that can lead to further shaking. Additionally, perform regular maintenance checks on your brake system, including inspecting calipers and brake lines for any signs of wear or leaks. If you notice any unusual noises, such as squealing, this may indicate that the brake pads or rotors need immediate attention. By following this diagnostic approach, you can effectively troubleshoot and resolve shaking issues, ensuring a safer and more comfortable driving experience in your Audi 90.

What Causes Shaking When Braking in an Audi 90?

When your Audi 90 experiences shaking during braking, it can be attributed to several common problems that are crucial to identify for effective DIY repairs. One of the primary culprits is warped brake rotors, which can cause uneven contact with the brake pads, leading to vibrations. Additionally, old or unevenly worn brake pads may not grip the rotors consistently, exacerbating the shaking. It's also important to check for sticky brake calipers, as they can hinder the smooth operation of the braking system. Beyond the brakes, worn tires can significantly impact vehicle stability, especially if they are unevenly worn or improperly inflated. Suspension issues, such as worn control arm bushings or poor alignment, can further contribute to the shaking sensation. Lastly, don’t overlook the condition of the caliper slide pins and the possibility of bent wheels, as these can also lead to vibrations when braking. By addressing these common problems through regular maintenance and timely replacements, you can ensure a safer and smoother driving experience in your Audi 90.

Why is My Audi 90 Shaking When I Brake?

When your Audi 90 shakes while braking, it’s crucial to understand that this symptom should not be ignored. The shaking is often indicative of underlying issues such as warped brake rotors or worn tires, which can compromise your vehicle's braking efficiency and safety. If left unaddressed, these problems can escalate, potentially leading to more severe damage to the brake system or suspension components, resulting in costly repairs. Additionally, the vibrations can affect your control over the vehicle, increasing the risk of accidents. Therefore, it is essential to conduct a thorough inspection of your brake system and related components at the first sign of shaking. Regular maintenance, including timely replacement of brake pads and rotors, not only enhances your driving experience but also ensures your safety on the road. Taking proactive measures can prevent minor issues from becoming major safety hazards.
