The BMW E90 is a widely beloved generation of the BMW 3 Series, known for its elegant design, advanced technology, and exceptional driving experience. Among the many features of the E90 is the handbrake, which provides safety and stability when the car is parked. However, one often overlooked but essential part of the parking brake system is the E-brake boot. This small yet significant part plays a key role in maintaining the functionality, aesthetics, and overall driving experience of the vehicle.
In this article, we’ll explore the importance of the E90 E brake boot, how to replace it, and how to care for it. Whether you’re a BMW owner looking to maintain your car or an enthusiast wanting to learn more, this guide will cover everything you need to know.
What is an E90 E Brake Boot?
The E90 E-brake boot is the protective covering that surrounds the parking brake lever, also known as the handbrake, inside the car. The primary function of the boot is to provide a clean and visually appealing cover for the mechanism underneath. It serves to keep dirt, moisture, and debris away from the mechanical components of the handbrake, helping to ensure that the parking brake works smoothly for the lifetime of the vehicle.
Additionally, the E90 E Brake Boot contributes to the overall aesthetic appeal of the interior of the car. The material, stitching, and design of the boot are often chosen to complement the vehicle’s interior, providing a more polished and refined look.
Functions of the E-Brake Boot in the BMW E90
While the E90 E-brake boot might seem like a purely decorative component, it serves several important functions.
Protection of the Handbrake Mechanism
The E-brake boot prevents dust, moisture, and debris from reaching the internal components of the parking brake mechanism. This helps to reduce wear and tear on the handbrake system, ensuring that it remains functional for a longer period of time.
Enhanced Aesthetics
The boot is often made from high-quality materials such as leather, faux leather, or durable fabrics, making it an important part of the car’s interior design. It contributes to the overall look and feel of the cabin, adding a touch of luxury and refinement to the vehicle.
Comfort and Grip E90 E Brake Boot
The boot’s design also plays a role in enhancing the driver’s experience. For example, a well-designed E-brake boot provides a comfortable grip for the driver when engaging or disengaging the parking brake. The material choice often ensures a good balance between tactile comfort and durability.
Noise Reduction
By providing a soft layer of material between the handbrake lever and the surrounding surfaces, the E-brake boot can help to reduce noise when the brake is engaged or released. This helps create a more pleasant driving experience, as there will be less rattling or clunking sounds from the handbrake mechanism.
Types of E90 E-Brake Boots
While the E90 E brake boot serves the same essential purpose across all models, the specific design, material, and color can vary. There are several types of E-brake boots available, each offering different styles and materials.
OEM (Original Equipment Manufacturer) E-Brake Boots
OEM parts are the ones directly produced by BMW for the E90 model. These boots are designed to match the factory specifications, ensuring a perfect fit and finish. OEM boots are typically made of high-quality leather or vinyl, and they come in colors that match the interior trim of the car. If you are looking for a seamless, factory-original look, OEM parts are the best option.
Aftermarket E-Brake Boots
Aftermarket E-brake boots are produced by third-party manufacturers. These boots can come in a variety of materials and styles, offering more customization options than the OEM parts. Aftermarket boots may include alternative stitching patterns, different color options, and even custom materials such as suede or carbon fiber. These boots often provide a more unique and personalized look for those who want to customize their vehicle’s interior.
Leather vs. Fabric
The most common materials used for E90 E-brake boots are leather and fabric. Leather offers a luxurious, high-end appearance, with a soft, smooth texture that feels great in hand. Leather boots are also very durable and easy to clean. Fabric boots, on the other hand, may be softer and more breathable, though they might not offer the same level of durability as leather.
When Should You Replace the E90 E Brake Boot?
While the E90 E-brake boot is designed to last, there are certain circumstances in which it may need to be replaced.
Visible Wear and Tear
Over time, the E-brake boot can become worn, torn, or damaged due to repeated use. The material may crack or fray, especially if exposed to excessive sunlight, heat, or moisture. If the boot becomes unsightly or damaged, it’s time for a replacement.
Foul Odor
If the E-brake boot is made of leather and the car has been exposed to moisture, there’s a chance that the boot can start to develop a bad odor. This often happens when the leather becomes damp and doesn’t dry out properly. In this case, replacing the boot may be the best option to restore the interior’s freshness.
Loose or Worn-out Fit
Over time, the fit of the E90 E Brake Boot may become loose or compromised. If the boot no longer stays in place, it may cause discomfort while driving, and it can also detract from the vehicle’s appearance. A worn-out fit may also allow dirt and debris to get inside the boot, which could lead to mechanical issues with the handbrake system.
Upgrading Interior Aesthetics
If you’re looking to upgrade the aesthetics of your E90’s interior, replacing the E-brake boot with a custom or upgraded version can be a quick and affordable way to refresh the cabin. A new boot can add a touch of luxury and personality to your vehicle’s interior.
How to Replace the E90 E-Brake Boot
Replacing the E90 E-brake boot is a relatively simple process that can be done at home with some basic tools.
Steps for Replacement:
Remove the Center Console Trim
To begin, you’ll need to remove the center console or the surrounding trim around the parking brake lever. This may involve removing screws or using a trim removal tool to gently pry off the panels.
Remove the Old E90 E Brake Boot
Once the trim is removed, you should have access to the E-brake boot. The boot is typically attached using clips, screws, or adhesive, so you’ll need to detach it carefully. Take note of how the boot is attached, as you’ll need to install the new boot in the same manner.
Install the New E-Brake Boot
Align the new boot with the handbrake mechanism, ensuring it fits properly and covers the area securely. Use the clips or screws to attach it in place, making sure that it’s tight and properly secured. Check for any wrinkles or loose areas in the boot and adjust as necessary.
Reassemble the Center Console
Once the boot is in place, carefully reassemble the center console and trim. Ensure everything is properly aligned, and all screws or clips are replaced.
Final Check
After replacing the boot, give it a final inspection. Make sure it looks clean, is tightly secured, and does not obstruct the handbrake operation. Check for any signs of movement or discomfort when using the handbrake lever.
Caring for Your E90 E-Brake Boot
Proper maintenance can help prolong the life of your E90 E brake boot, keeping it looking good and functioning well for years.
Regular Cleaning
If your E-brake boot is made from leather, fabric, or vinyl, it’s important to keep it clean. Use a soft cloth and mild cleaner to wipe away dirt and debris regularly.
Condition Leather Boots
If you have a leather E-brake boot, it’s important to apply a leather conditioner occasionally to keep the material soft and prevent cracking. Conditioning helps maintain the boot’s appearance and durability over time.
Protect from Sunlight and Moisture
Excessive exposure to direct sunlight or moisture can damage the E-brake boot, particularly if it’s made from leather. Park in the shade when possible, and avoid leaving your car in damp conditions for extended periods.
Inspect for Damage
Periodically inspect the boot for any signs of damage, such as tears, rips, or loose stitching.
Conclusion
The BMW E90 E brake boot may be a small part of the car, but it plays a crucial role in both the functionality and appearance of the vehicle. It protects the handbrake mechanism, enhances the interior, and offers comfort and convenience to the driver.
