The Role of Hydraulic Fluid in Your Braking System Your car's ability to stop safely relies on hydraulic fluid to help amplify the pressure you apply to the brake pedal. This fluid is essential for stopping a heavy, fast-moving vehicle with ease, which is why it's important to regularly maintain it for optimal performance.   Why Brake Fluid Flushes are Necessary During a brake fluid flush, old fluid is removed and replaced with fresh fluid to maintain the smooth operation of your braking system and prevent issues from arising. There are three main issues that can arise in your braking system, making regular brake fluid flushes crucial: Breakdown from Heat - The heat generated during braking can cause the brake fluid to break down over time. Rust Formation - Moisture residue left behind can lead to rust forming within the brakes. Contamination - Debris, rubber, and metal particles can contaminate th ... read more

The Problem with Transmission Failure Every year in the United States, over 13 million automatic transmissions fail, and that's a big issue. Research shows that almost 90% of these failures happen because the transmission overheats and the fluid gets contaminated. The main reason for this is the Automatic Transmission Fluid (ATF) getting oxidized, which makes it lose its protective abilities. Heat is a major factor in this oxidation process. Why Transmissions Fail Modern engines are smaller and faster, and with more stop-and-go driving, the ATF is exposed to higher temperatures, causing it to break down faster. The transmission is like the heart of the engine, providing power to the vehicle. With 800 parts, it takes an expert to fix any problems that arise. The Importance of Maintenance When small particles like metal shavings get into the transmission fluid, they can cause clogs and wear on the transmission components as they ... read more
