At Meta Mechanics, we understand that the performance of your Audi S5’s braking system is crucial to your safety and driving experience. One of the most essential, yet often overlooked, maintenance tasks for your braking system is brake oil (brake fluid) replacement. Over time, brake fluid can absorb moisture, leading to reduced braking performance and even damage to the brake system. That’s why we recommend regular brake oil changes to keep your Audi S5 performing at its best.
Here’s an overview of the Audi S5 brake oil change service we recently performed and why this is so important for your vehicle’s safety and performance.
What We Found:
Upon inspection of the Audi S5’s brake system, we found the following regarding the brake oil:
- Brake Fluid Contamination
- Problem: The brake fluid had become contaminated with moisture, which can cause the fluid to lose its effectiveness and lead to corrosion of brake system components like the calipers and master cylinder. Moisture absorption can also lower the boiling point of the brake fluid, which may cause brake fade under high-stress driving conditions.
- Solution: We flushed the contaminated brake fluid from the entire braking system and replaced it with high-quality, OEM-grade DOT 4 brake fluid, which is compatible with your Audi S5’s braking system.
- Low Brake Fluid Levels
- Problem: The brake fluid was also lower than recommended levels, which can indicate leaks in the braking system or simply that it had been a while since the fluid was replaced.
- Solution: After replacing the fluid, we topped it up to the correct level and ensured that the brake fluid reservoir was sealed properly.
- Air in the Brake Lines
- Problem: Air in the brake lines can lead to a soft brake pedal feel and reduced braking efficiency, as air compresses when pressure is applied, unlike brake fluid.
- Solution: We performed a full brake fluid bleeding procedure to remove any air from the brake lines, ensuring the brake pedal feels firm and responsive once again.
- Brake Fluid Quality Check
- Problem: The brake fluid was showing signs of significant degradation, with a darker color indicating a loss of fluid quality and performance.
- Solution: In addition to flushing and replacing the brake fluid, we checked the condition of the brake fluid reservoir and all related components to ensure there were no underlying issues.
