JMACX brake boosters incorporate hydraulic brake assist technology, which amplifies the brake force applied by the driver. This results in shorter stopping distances and improved braking control, especially in emergency situations.

2. Direct Fitment

JMACX brake boosters are designed as direct replacements for the OEM (Original Equipment Manufacturer) brake boosters. This ensures easy installation and compatibility with existing braking systems, without the need for extensive modifications.

3. Heavy-Duty Construction

JMACX brake boosters are built to withstand the demanding conditions of off-road driving. They are constructed using durable materials and feature robust components that can withstand the rigors of harsh terrains.

4. Optimized Pedal Feel

JMACX brake boosters provide an enhanced pedal feel, allowing for better modulation and control during braking. This ensures a more responsive and intuitive braking experience, giving drivers greater confidence on the trails.

5. Improved Braking Power

By increasing the braking force, JMACX brake boosters significantly enhance the overall braking power of off-road vehicles. This allows for better control and shorter stopping distances, providing a safer and more enjoyable off-road experience.


Benefits of JMACX Brake Boosters

Investing in JMACX brake boosters can offer a range of benefits for off-road enthusiasts. Here are some advantages you can expect:

1. Enhanced Safety

With increased braking power and improved pedal feel, JMACX brake boosters contribute to safer off-road driving. They provide the confidence and control needed to navigate challenging terrains and handle unexpected obstacles.

2. Optimal Off-Road Performance

JMACX brake boosters are specifically designed for off-road applications, ensuring optimal performance in rugged environments. The enhanced braking power allows for precise control and maneuverability, even on steep descents or slippery surfaces.

3. Reduced Brake Fade

Brake fade is a common issue during intense off-road driving, where repeated braking can cause a loss of braking performance. JMACX brake boosters help mitigate brake fade by providing consistent and powerful braking, even in demanding situations.

4. Compatibility with Suspension Systems

JMACX brake boosters are designed to work seamlessly with JMACX suspension setups. The combination of enhanced suspension and braking systems ensures a harmonious and balanced off-road driving experience.

5. Ease of Installation

JMACX brake boosters are engineered as direct replacements for OEM brake boosters, simplifying the installation process. With proper tools and basic mechanical knowledge, installation can be completed without extensive modifications or professional assistance.


Installation of JMACX Brake Boosters

Installing JMACX brake boosters requires basic mechanical knowledge and tools. While it’s always recommended to have a professional perform the installation, experienced DIYers may choose to tackle the task themselves. Here are some essential steps for a successful installation:

1. Gather the Necessary Tools and Equipment

Before starting the installation, gather all the necessary tools and equipment. This may include a socket set, wrenches, brake fluid, hydraulic jack, jack stands, and a torque wrench. It’s also crucial to have the appropriate service manual or installation instructions provided by JMACX.

2. Follow Safety Precautions

Working on the braking system requires caution and adherence to safety measures. Ensure that the vehicle is securely lifted using appropriate jack stands and take necessary precautions to prevent accidents. It’s recommended to wear safety goggles, gloves, and other protective gear during the installation.

3. Remove the OEM Brake Booster

Start by removing the OEM brake booster from the vehicle. This typically involves disconnecting the brake lines, vacuum hose, and any mounting bolts. Follow the instructions provided by JMACX to ensure a proper and safe removal process.

4. Install the JMACX Brake Booster

Once the OEM brake booster is removed, proceed with the installation of the JMACX brake booster. Follow the provided instructions carefully, ensuring proper alignment and secure fastening of all components. Connect the brake lines and vacuum hose as per the manufacturer’s guidelines.

5. Bleed the Brake System

After the installation, it’s crucial to bleed the brake system to remove any air bubbles and ensure proper brake fluid circulation. Follow the recommended bleeding procedure provided by JMACX or consult a professional if needed.

6. Test and Verify Braking Performance

Once the brake booster installation and bleeding process are completed, test the braking system to ensure proper functionality. Gradually apply the brakes and check for any abnormalities or leaks. If everything is functioning correctly, take the vehicle for a short test drive to verify the improved braking performance.

JMACX brake boosters are primarily designed as upgrades for OEM braking systems. While they may work with certain aftermarket braking systems, it's recommended to consult with JMACX or a professional for compatibility and performance considerations.

JMACX brake boosters enhance braking performance off-road by increasing the braking force applied to the wheels. This allows for shorter stopping distances, improved pedal feel, and better control over the vehicle in challenging terrains.

JMACX brake boosters comply with relevant safety regulations and are designed for both on-road and off-road use. However, it's essential to verify and comply with local laws and regulations regarding aftermarket modifications to braking systems.

JMACX provides a warranty for their brake boosters, which may vary depending on the specific product. It's recommended to consult the manufacturer or authorized dealer for detailed warranty information and terms.

Jmacx is an Australian company that specializes in manufacturing aftermarket parts for off-road vehicles. Their brake boosters are also manufactured in Australia.

It is not strictly necessary to replace the brake lines with braided brake lines when installing a Jmacx brake booster. However, some customers may choose to upgrade their brake lines as well for improved braking performance.
Braided brake lines are more durable than traditional rubber brake lines. They can also provide improved brake pedal feel and responsiveness, as they are less likely to expand or bulge under pressure. This can result in a firmer brake pedal and more precise braking control.Improved durability: Braided brake lines are typically made from stainless steel, which is more resistant to wear and tear than rubber. This can increase the lifespan of the brake lines and reduce the risk of leaks or failures.

Usually between 1 and 2 hours, depending on the experience of the mechanic

It is not necessary but it is recommended to use DOT 5.1 brake fluid that has a higher boiling point than DOT 3 or DOT 4 brake fluids. This means it can withstand higher temperatures without boiling, which can improve braking performance and reduce the risk of brake fade in high-performance or heavy-duty applications.

While high-performance brake pads can provide better stopping power and reduce brake fade, they do not provide additional force to the brake system. The brake booster, on the other hand, amplifies the force applied by the driver on the brake pedal, making it easier to apply the brakes and reduce the speed of the vehicle.
