Brake Line Locks, Roll Control Kits & Components

What Is a Brake Line Lock?

A brake line lock, commonly referred to as a "line lock" in the automotive world, is a valuable component used in drag racing and other high-performance driving applications. Its primary purpose is to lock the front brakes while allowing the rear wheels to spin freely. This feature is especially useful for achieving a controlled burnout or launching a vehicle with maximum rear wheel power.

Here's how a line lock works:

1. **Appy Pressure To Brakes:**The driver applies foot brake pedal to build up pressure in the front brake system.

2. **Activation:** While holding the brake pedal to maintain brake pressure, the line lock system is activated, which closes off the front brake line, effectively trapping hydraulic pressure in the front brake circuit. The driver can then take their foot of off the brake pedal, which allows the rear brakes to release

3. **Rear Wheels Free:** The line lock allows the rear brake circuit to remain open, enabling the rear wheels to rotate freely.

4. **Controlled Burnout:** The driver can now apply throttle to the rear wheels without the vehicle moving forward. This setup is ideal for achieving a controlled burnout or launching a vehicle with a strong, wheel-spinning start.

Will a Line Lock Work for a Parking Brake?

While line locks are primarily designed for performance applications and controlled burnouts, they are not suitable for use as a parking brake replacement in regular on-road vehicles.

Line locks are not designed to hold a vehicle stationary for extended periods, as a parking brake does. They lack the mechanical components and stability required for long-term parking. Using a line lock as a parking brake replacement can lead to brake system damage and safety hazards.

It's essential to maintain your vehicle's standard parking brake system for regular parking situations. Line locks are intended for temporary use during specific performance applications on the racetrack.

How Much Does a Brake Line Lock Kit Cost?

The cost of a brake line lock kit can vary depending on the brand, features, and included components. Here's a general price range to give you an idea of what to expect:

1. **Basic Line Lock Kits:** Entry-level line lock kits typically range from $50 to $100. These kits provide the essential components for line lock activation.

2. **Advanced Kits:** More advanced kits with additional features may cost between $100 and $200. These kits may include improved durability, better control options, and installation hardware.

3. **Professional-Grade Kits:** Professional-grade line lock kits, often used by serious racers, can range from $200 to $300 or more. These kits offer advanced performance and durability.
