Motorcycle Drum Brake To Disk Brake Conversion
Motorcycles are one of the most preferred modes of transportation for many people. They offer a sense of freedom and thrill that cannot be equaled by any other vehicle. However, with the advancement in technology, motorcycles have evolved, and so have their braking systems. The traditional drum brakes, which were once the norm, have now been replaced by disk brakes. In this article, we will discuss everything you need to know about motorcycle drum brake to disk brake conversion.
Why Convert from Drum to Disk Brake?
Before diving into the process of conversion, let's first understand why you may need to convert from drum to disk brakes. There are several reasons why you may want to do this:
- Better Braking Performance: Disk brakes provide better stopping power than drum brakes. They are more responsive and offer better control, especially in emergency situations.
- Longer Lifespan: Disk brakes last longer than drum brakes, and they require less maintenance. This means that you will save money in the long run since you won't have to replace the brake pads or shoes as often.
- Improved Heat Dissipation: Disk brakes dissipate heat more efficiently than drum brakes, which reduces the risk of brake fade. This is especially important for high-performance motorcycles that are ridden aggressively.
- Upgraded Appearance: Disk brakes look more modern and stylish than drum brakes. This is a purely cosmetic reason, but it can make a significant difference in the overall appearance of your motorcycle.
What You Need for the Conversion
Before you start the conversion process, you need to gather all the necessary tools and equipment. Here's what you will need:
- New Disc Brake Assembly: This is the most critical component of the conversion. You will need to purchase a disc brake assembly that is compatible with your motorcycle.
- Caliper Mounting Bracket: You will need a caliper mounting bracket that is designed to fit your motorcycle's fork leg or swingarm.
- New Brake Lines: You will need to replace your old brake lines with new ones that are compatible with the new disc brake assembly.
- Brake Pads: You will need to purchase new brake pads that are designed to work with your new disc brake assembly.
- Wrenches and Sockets: You will need a set of wrenches and sockets to remove the old drum brake assembly and install the new disc brake assembly.
- Brake Fluid: You will need to bleed the brake system after the installation is complete, so make sure you have enough brake fluid on hand.
The Conversion Process
The conversion process can be broken down into several steps:
Step 1: Remove the Old Drum Brake Assembly
The first step is to remove the old drum brake assembly. Start by disconnecting the brake cable from the brake lever or pedal. Then, remove the brake shoes or pads, springs, and retainers. Next, remove the brake drum from the wheel hub. If your motorcycle has a rear drum brake, you may also need to remove the sprocket and chain.
Step 2: Install the Caliper Mounting Bracket
The next step is to install the caliper mounting bracket. The bracket should be attached to the fork leg or swingarm using the bolts provided. Make sure the bracket is aligned correctly and tightened securely.
Step 3: Install the New Disc Brake Assembly
Once the caliper mounting bracket is in place, you can install the new disc brake assembly. Start by attaching the brake rotor to the wheel hub using the bolts provided. Then, attach the caliper to the mounting bracket using the bolts provided. Make sure the caliper is aligned correctly and tightened securely.
Step 4: Install the Brake Pads and Brake Lines
The next step is to install the brake pads and brake lines. Start by inserting the brake pads into the caliper. Then, attach the brake lines to the caliper and the master cylinder. Make sure the brake lines are routed correctly and tightened securely.
Step 5: Bleed the Brake System
The final step is to bleed the brake system. This is necessary to remove any air bubbles that may have entered the brake lines during the installation process. To do this, fill the master cylinder with brake fluid and attach a clear plastic hose to the bleeder valve on the caliper. Then, pump the brake lever or pedal until all the air bubbles have been removed from the system.
Conclusion
Converting from drum to disk brakes is a relatively simple process that can be done by most motorcycle enthusiasts. It offers several benefits, including improved braking performance, longer lifespan, improved heat dissipation, and an upgraded appearance. However, it's essential to ensure that you have all the necessary tools and equipment before starting the conversion process. Also, make sure you follow the steps outlined in this article to ensure a successful and safe conversion.
