How to Flush Brake Fluid System 00-06 Chevy Silverado 2500 Diesel

Summary

In this video, Mike from One Auto demonstrates the process of flushing old, contaminated brake fluid and replacing it with fresh fluid to restore proper braking performance. He explains how brake fluid absorbs moisture over time, leading to reduced braking efficiency, and provides detailed instructions on how to safely remove old fluid using a turkey baster, clean the system, and flush the brake lines. Mike emphasizes the importance of regular brake fluid maintenance to avoid dangerous performance issues and highlights the proper disposal of old fluid. The video provides a step-by-step guide for DIYers looking to maintain their vehicle's braking system.

Takeaways

• 😀 Brake fluid is hydroscopic, meaning it absorbs water over time, which can degrade braking performance.
• 😀 Dirty brake fluid can contain moisture, dirt, and rust particles, which can clog the brake system and reduce performance.
• 😀 Always follow the vehicle's owner's manual for recommended brake fluid flush intervals to maintain optimal braking performance.
• 😀 Use a dedicated turkey baster to remove old brake fluid, as it cannot be reused for anything else once used for this purpose.
• 😀 Brake fluid is toxic and can damage paint, so it's essential to wear gloves and dispose of it properly in a sealed container.
• 😀 If the brake fluid is visibly dirty or discolored (brown or greenish), it is an indicator that it needs to be flushed and replaced.
• 😀 Start brake fluid flushing with the passenger side rear wheel, followed by the driver's side rear, passenger side front, and finally the driver's side front wheel.
• 😀 Use a special hose and container to catch the old brake fluid when loosening the bleeder screw, preventing spills and mess.
• 😀 Always keep the master cylinder topped off with brake fluid during the flushing process to ensure proper fluid flow.
• 😀 Regular brake fluid flushing can significantly improve braking performance, even if the fluid is not completely clean after the process.

Q & A

What is the main issue with the vehicle's braking system in the video?

The main issue is poor braking performance despite having new brakes. Upon inspection, the brake fluid was found to be old and dirty, which affects braking efficiency.

Why does brake fluid need to be changed periodically?

Brake fluid is hygroscopic, meaning it absorbs water over time. This leads to the contamination of the fluid with dirt and moisture, which can negatively affect braking performance and system reliability.

What tool is used to remove old brake fluid from the reservoir?

A turkey baster is used to remove the old brake fluid from the reservoir. It's important to use a dedicated baster for this purpose to avoid contamination with other substances.

What is the color of new brake fluid compared to old brake fluid?

New brake fluid is clear, clean, and typically golden yellow in color. In contrast, old brake fluid is often brown, greenish, and dark due to the accumulation of dirt, moisture, and rust particles.

Why is old brake fluid harmful to the braking system?

Old brake fluid contains water, which can boil when exposed to high temperatures or freeze in cold conditions. This compromises braking performance and could lead to brake failure.

What precautions should be taken when handling brake fluid?

Brake fluid is toxic and can damage paint, so it’s essential to wear gloves while handling it. Additionally, it should be disposed of properly to avoid environmental harm.

How does the brake fluid flush procedure begin?

The procedure begins by using the turkey baster to remove as much old brake fluid as possible from the reservoir. The rest will be flushed through the system by opening the brake bleeder screws.

What is the correct order for flushing brake fluid from the vehicle?

The recommended order for flushing the brake fluid is starting with the passenger side rear (the furthest from the reservoir), followed by the driver's side rear, passenger side front, and finally the driver's side front (the closest to the reservoir).

What is the purpose of the custom bottle setup mentioned in the video?

The custom bottle setup is designed to collect the old brake fluid when the bleeder screw is opened. The fluid flows through a hose attached to the bottle, preventing spillage and ensuring proper fluid collection.

Why is it important to clean the bleeder screw area during the fluid change?

Cleaning the bleeder screw area is essential to ensure there is no rust or debris obstructing the brake fluid flow. It also prevents contamination from entering the brake system during the flushing process.
