Abs Delete Kit Installation And Brake System Modifications

Modifying your vehicle's braking system is a serious undertaking. When considering an ABS delete kit installation, it's crucial to understand the implications, legal considerations, and the necessary steps involved. This article provides a comprehensive overview of ABS delete kits, brake system modifications, and essential factors to consider before making any changes.

What is an ABS Delete Kit?

ABS, or Anti-lock Braking System, is a safety feature designed to prevent wheel lockup during hard braking, allowing the driver to maintain steering control. An ABS delete kit essentially removes this system, replacing it with a more traditional, non-ABS brake setup. These kits are typically favored in racing applications or older vehicles where ABS systems are problematic or unavailable.

The kit generally includes components such as:

Brake lines: Custom-made brake lines to bypass the ABS module.
Proportioning valve: Allows you to manually adjust the front-to-rear brake bias.
Fittings and adapters: Necessary hardware for connecting the new components.
Master cylinder (optional): Some kits include a new master cylinder optimized for non-ABS systems.

Why Consider an ABS Delete?

While ABS is a valuable safety feature for everyday driving, there are several reasons why someone might choose to install an ABS delete kit:

Racing Applications: In racing, drivers often prefer the direct feel and predictability of a non-ABS system. They want complete control over brake modulation, allowing them to fine-tune braking performance for optimal lap times.
Simplicity and Reliability: Older ABS systems can be prone to failure and expensive to repair. An ABS delete offers a simplified brake system with fewer components that could potentially fail.
Weight Reduction: Removing the ABS module and associated components can result in a slight weight reduction, which can be beneficial in performance-oriented applications.
Customization: Allows for greater customization of the brake system to suit specific needs and preferences.
Off-Road Use: In certain off-road scenarios, ABS can interfere with traction, especially in loose gravel or sand. Deleting ABS can improve braking performance in these conditions.

Important Considerations Before Installation

Before you even consider an ABS delete kit installation, there are several crucial factors to take into account:

Legality

The legality of removing ABS varies depending on your location. In many jurisdictions, it's illegal to disable or remove safety features like ABS on vehicles intended for public roads. Check your local laws and regulations thoroughly before proceeding. Operating a vehicle with a modified brake system that doesn't meet legal requirements could result in fines, impoundment, or failure to pass inspection.

Safety Implications

Removing ABS significantly alters the braking characteristics of your vehicle. Without ABS, you'll need to be much more careful and skilled in braking, especially in emergency situations or on slippery surfaces. You'll be responsible for preventing wheel lockup yourself, which requires a good understanding of brake modulation. Failure to do so can lead to skidding, loss of control, and potentially serious accidents. Understand that you are taking away a vital safety net.

Insurance Implications

Modifying your brake system, especially by removing a safety feature like ABS, could affect your insurance coverage. Insurance companies may view this type of modification as increasing the risk of accidents and either deny coverage or charge higher premiums. Contact your insurance provider to discuss the potential implications before making any changes.

Skill and Expertise

Installing an ABS delete kit and modifying your brake system is not a simple DIY project. It requires a high level of mechanical skill, knowledge of brake systems, and access to specialized tools. If you're not comfortable working on brakes, it's strongly recommended to have the work done by a qualified and experienced mechanic. A mistake during installation could have catastrophic consequences.

Steps Involved in ABS Delete Kit Installation

While the specific steps may vary depending on the vehicle and the kit, here's a general overview of the ABS delete kit installation process:

Preparation: Gather all the necessary tools, parts, and safety equipment. Disconnect the negative battery terminal. Thoroughly read the instructions provided with the kit.
ABS Module Removal: Locate the ABS module and disconnect all electrical connectors and brake lines attached to it. Carefully remove the module from the vehicle.
Brake Line Installation: Install the new brake lines according to the kit's instructions. Ensure all connections are tight and properly sealed to prevent leaks.
Proportioning Valve Installation: Install the proportioning valve in a convenient location that allows for easy adjustment. Connect the brake lines to the valve, ensuring proper routing and secure connections.
Master Cylinder Replacement (if applicable): If the kit includes a new master cylinder, remove the old one and install the new one according to the instructions. Bleed the master cylinder before connecting it to the brake lines.
Brake Bleeding: Bleed the entire brake system to remove any air from the lines. This is a critical step to ensure proper brake function. Use the correct bleeding procedure for your vehicle.
Testing and Adjustment: After bleeding the brakes, test the system thoroughly. Check for leaks and ensure the brakes are functioning properly. Adjust the proportioning valve to achieve the desired front-to-rear brake bias.
Final Inspection: Double-check all connections and components to ensure everything is secure and properly installed. Take the vehicle for a test drive in a safe area to verify brake performance.

Brake System Modifications Beyond ABS Delete

An ABS delete is often just one part of a larger brake system modification project. Other common modifications include:

Bigger Brake Rotors and Calipers

Upgrading to larger rotors and calipers increases the braking surface area and improves heat dissipation, resulting in greater stopping power and reduced brake fade.

Performance Brake Pads

Performance brake pads offer higher friction coefficients and can withstand higher temperatures, providing improved braking performance and shorter stopping distances.

Stainless Steel Brake Lines

Stainless steel brake lines resist expansion under pressure, providing a firmer brake pedal feel and more consistent braking performance compared to rubber lines.

Master Cylinder Upgrade

Upgrading to a larger master cylinder can improve brake pedal feel and modulation, especially when combined with other brake system modifications.

Seeking Professional Help

Due to the complexity and critical nature of brake system modifications, it's highly recommended to consult with a qualified mechanic or brake specialist before undertaking any work. A professional can assess your needs, recommend appropriate components, and ensure that the installation is done safely and correctly.

"Modifying your brakes is not a decision to be taken lightly. Your safety, and the safety of others, depends on a properly functioning braking system."

Conclusion

Installing an ABS delete kit and modifying your brake system can offer certain benefits, particularly in racing or specialized applications. However, it's essential to carefully consider the legal, safety, and insurance implications before proceeding. If you're not comfortable working on brakes or lack the necessary expertise, seek professional help to ensure the job is done correctly and safely. Always prioritize safety and compliance with local laws and regulations when modifying your vehicle's braking system.
