Why You Should Replace the Oil Seal When Replacing Our Upgraded Dust Boot

For car owners who enjoy aggressive driving or participate in track racing, the stability and durability of the brake system are crucial. Our upgraded silicone dust boot can withstand up to 300°C, much higher than the 150°C tolerance of OEM dust boots. This allows it to handle the high temperatures encountered during aggressive driving or track racing, effectively protecting the brake pistons from dust, dirt, and moisture. However, when the stock dust boot breaks, brake dust and dirt can enter the area between the piston and cylinder, which can cause the oil seal and piston to become contaminated, leading to oil leakage or sticking. Therefore, we strongly recommend replacing the oil seal at the same time you replace the dust boot. Here are some key reasons why:

1. Dirt and Contamination Enter the System When the Dust Boot Breaks, Damaging the Oil Seal

The primary function of the dust boot is to protect the brake piston and cylinder from brake dust, dirt, and moisture. When the dust boot breaks, these contaminants can enter the system, causing the oil seal and piston to become contaminated. This contamination can lead to the oil seal's failure, causing leakage or sticking, which negatively impacts the brake system's performance.

2. Prevent Oil Leakage or Sticking, Keeping the Brake System Stable

When the dust boot breaks and contaminants enter the oil seal area, the oil seal may become contaminated and lose its sealing ability, which can result in oil leakage. The failure of the oil seal will cause insufficient lubrication, and in some cases, it could lead to the brake piston sticking. Replacing the oil seal promptly can prevent these issues and ensure the brake system remains stable, providing safer driving.

3. Ensure Long-Term Stability of the High-Performance Brake System

Whether you're driving aggressively or racing, the performance of the brake system is critical. The proper coordination between the dust boot and oil seal ensures that your brake system not only operates smoothly under high-temperature conditions but also performs optimally during regular use. By replacing both the dust boot and oil seal at the same time, you maximize the lifespan of your brake system and prevent unnecessary failures.

4. Save on Future Repair Costs

While replacing both the dust boot and oil seal may involve some initial cost, this maintenance will help prevent higher repair costs caused by oil seal damage, insufficient lubrication, or brake piston sticking. Addressing these issues in advance can save you future repair expenses and ensure your brake system remains efficient.

Conclusion:

Our upgraded silicone dust boot offers superior high-temperature protection, but when stock dust boots break, contaminants like brake dust and dirt enter the brake system, contaminating the oil seal and leading to oil leakage or sticking. To maintain optimal brake system performance and prevent unnecessary failures and repairs, we recommend replacing the oil seal at the same time as the dust boot. This ensures your brake system remains stable and reliable, even after aggressive driving or track use.
