At Meta Mechanics, we specialize in providing top-tier service for high-performance vehicles like the Audi RS4. The front brake pads are among the most critical components of your braking system, as they handle the majority of the stopping power. Recently, we had the opportunity to perform a front brake pad replacement on an Audi RS4, and through our thorough inspection, we identified several additional issues that were affecting the vehicle’s braking performance. We quickly addressed these to ensure the vehicle was restored to peak performance.
What We Found and the Solutions We Provided
1. Severely Worn Front Brake Pads
Problem: The front brake pads were nearly worn to their minimum thickness, which was causing a decrease in braking efficiency. This can result in longer stopping distances, a spongy brake pedal feel, and potential damage to the rotors.
Solution: We replaced the old, worn-out brake pads with high-quality, OEM (Original Equipment Manufacturer) pads specifically designed for the Audi RS4. These premium pads offer optimal stopping power, reduced noise, and superior performance, restoring the vehicle’s braking ability to its original specifications.
2. Grooved and Scored Brake Rotors
Problem: Upon inspecting the rotors, we noticed that the front brake rotors were grooved and scored, likely due to the worn brake pads not providing even contact. This can cause vibrations during braking and further wear on the new brake pads.
Solution: To restore smooth braking performance, we resurfaced the front brake rotors. This process eliminates any grooves or scoring, ensuring that the new brake pads make consistent, even contact with the rotor surface. Resurfacing helps to prolong the life of both the rotors and the new pads.
3. Brake Fluid Contamination
Problem: We found that the brake fluid had become contaminated and had absorbed moisture over time. Moisture in the brake fluid can lead to reduced braking performance, increased risk of corrosion, and potential brake fade under high-stress conditions.
Solution: As part of our brake system service, we flushed the brake fluid and replaced it with fresh, high-quality brake fluid that meets Audi’s specifications. This helps maintain optimal hydraulic pressure within the braking system and ensures reliable, consistent braking performance.
4. Uneven Brake Pad Wear Due to Suspension Misalignment
Problem: The front brake pads were showing signs of uneven wear, likely due to suspension misalignment or other underlying issues. Uneven pad wear can lead to inefficient braking and premature pad degradation.
Solution: We performed a thorough inspection of the suspension and alignment system, and found that the front suspension had slight misalignment. We adjusted the alignment to ensure even brake pad wear and prevent future issues. Proper suspension alignment helps maintain balanced braking performance and extends the life of your brake components.
5. Brake Caliper Issues
Problem: The front brake calipers were functioning properly but showed signs of minor corrosion and slight leakage around the seals, which could potentially affect braking efficiency over time.
Solution: We cleaned the calipers and replaced any necessary seals to ensure they were in optimal working condition. This not only improves braking performance but also helps prevent future fluid leaks or loss of braking force.
