At Meta Mechanics, we pride ourselves on providing high-quality, expert service for your vehicle’s needs. Recently, we had the privilege of servicing an Audi RSQ5, where we performed a front brake pad replacement. During the inspection and replacement process, we discovered a few important issues that needed attention. Here’s a breakdown of what we found and the solutions we recommend to ensure your Audi stays in top condition.
Issues Identified:
- Excessive Brake Pad Wear:
- What We Found: The front brake pads on the Audi RSQ5 showed signs of significant wear. The friction material had worn down to nearly 2mm, well below the manufacturer’s recommended minimum of 3mm. This level of wear could reduce braking performance and increase stopping distances, which could be a safety concern.
- Solution: We replaced the brake pads with high-quality, OEM-grade pads to ensure optimal braking performance. Regular brake pad inspections are recommended every 10,000 to 15,000 miles to prevent premature wear.
- Uneven Brake Pad Wear:
- What We Found: The brake pads showed uneven wear, with the inner pads being more worn than the outer pads. This could indicate issues with the caliper, suspension, or brake hardware, leading to uneven pressure distribution during braking.
- Solution: After inspecting the brake system, we found that the caliper slide pins were sticking due to lack of lubrication and contamination. We cleaned and lubricated the pins, ensuring they move freely. We also checked the caliper for any signs of damage or misalignment and ensured everything was functioning correctly. If you notice similar uneven wear in the future, it’s best to bring your vehicle in for inspection.
- Brake Rotor Scoring:
- What We Found: The brake rotors on the Audi RSQ5 showed light scoring and grooves, which can develop over time due to debris or excessive wear on the brake pads. While not immediately dangerous, this could lead to decreased braking efficiency, vibration, or noise during braking.
- Solution: We performed a rotor resurfacing to remove the scoring, ensuring a smooth and even surface for the new brake pads. In cases where scoring is more severe, rotor replacement might be necessary, but this was not required for this particular service.
- Brake Fluid Condition:
- What We Found: Upon checking the brake fluid level and condition, we noticed the fluid had become discolored, which can indicate moisture contamination. Moisture in the brake fluid can reduce braking performance and potentially lead to brake failure, especially in high-stress situations.
- Solution: We recommended a brake fluid flush to remove the old fluid and replace it with fresh, high-performance brake fluid. We also inspected all brake lines and components for any signs of leaks, ensuring the system is fully sealed.
- Brake Pad Sensors:
- What We Found: The wear sensors on the brake pads were damaged, preventing them from sending accurate alerts to the vehicle’s onboard system. This can result in missed notifications regarding brake pad wear, leading to safety concerns.
- Solution: We replaced the brake pad sensors with new, OEM-approved sensors. This ensures your vehicle’s electronic system can properly monitor brake pad health and alert you when it’s time for another inspection.
