To dominate on the track or trail, you not only need to be able to accelerate quickly. On the contrary, you also must have confidence in your bike’s ability to stop on a dime. Unfortunately, though, stock braking systems don’t always deliver the dynamic performance that racing enthusiasts expect from their machines. Upgrading your bike’s stock rotor is a better strategy for beating the competition. Of course, you must know how to install a Galfer oversized brake rotor kit if you want to benefit from an advanced rotor. 

Galfer has long been an insider in making top-grade brake parts. That’s for good reason, as the company relies on innovative designs and modern technologies to help improve your bike’s performance. If you want to rework your dirt bike rotors, choosing an oversized rotor kit from Galfer is a recipe for success. In this guide, we give you step-by-step instructions for installing your new rotor kit correctly.

The Benefits

If you are riding on a bike with a stock rotor, you may not realize the advantages of upgrading to a larger rotor. Galfer’s oversized rotor gives you a 270mm upgrade. The large rotor displaces heat more effectively than smaller, stock rotors. The result is enhanced stopping for your dirt bike. If you take tight turns or jump your bike, having a larger rotor may help you achieve your riding goals. 

Essential Tools

Before you attempt to replace the smaller stock rotor on your bike with an oversized alternative, you need to be sure you have the right tools for the job. Luckily, you don’t need access to a mechanic’s shop to achieve professional-grade results. 

The benefit of purchasing an oversized brake rotor kit is getting everything you need to do the job. While your Galfer kit comes with a bracket, new brake pads, a caliper and rotor, you need to gather some tools before you start the job. 

Here is a list of tools you need for your new rotor install:

  • Torque wrench
  • Soft mallet
  • 8mm socket
  • A set of hex wrenches
  • A set of standard box wrenches

Step 1: Remove the Front Wheel

Removing your bike’s front wheel is an easy but necessary job when upgrading a stock rotor. Because different bikes have different hardware, you likely need a box wrench to take off the front wheel. It should attach with just a nut and bolt, though. 

Step 2: Remove Caliper Bracket

After you have removed and stored your bike’s front wheel, you can easily access the brake caliper bracket. On most machines, the bracket stays in place with just two bolts. Simply remove the bolts using a socket or box wrench. When you do, be careful not to strip or otherwise damage the bolts. If you do, plan to replace the bolts before finishing the project. 

Step 3: Remove Caliper Pins and Brake Pads

To access the caliper bracket, you must first remove the caliper pins. Depending on your bike, you may have one, two, three or more pins to remove. To detach the pins, simply use a hex wrench and slight pressure. After you have removed the pins, slide them out of the way. This allows you to access the brake pads, which you can then remove. 

Step 4: Transfer Parts

You do not want to discard some of the parts that come off your bike’s factory caliper bracket. Instead, you want to save the rubber grommet and pin to reuse with your new assembly. These items easily detach from the caliper bracket using an extended socket. 

Step 5: Install the Caliper Relocation Bracket

After you have transferred parts to your new bracket, you are ready to install the caliper relocation bracket. Using a minimal amount of grease on the caliper pins may help with the process. You must be careful not to use too much grease, though, as excessive grease may encourage your bike’s calipers to lock. Then, simply attach the caliper bracket using the reverse process of removing it.

Step 6: Replace Brake Pads

Before installing the caliper, replace your bike’s brake pads. Even if you think your pads have some life left, you want to swap them out for a new set. Remember, brake pads and rotors wear together. As such, whenever you replace a rotor, you should commit to replacing brake pads. 

Step 7: Install the Rotor

After you have torqued down your caliper assembly, you may install the rotor. To do so, remove the existing rotor’s factory hardware using wrenches or a socket. Then, put the upgraded rotor into place. You probably want to add some Loctite to the bolts to be sure they grip properly. Because you are using the factory bolts to install the rotor, you also want to examine each bolt for signs of damage. Also, check the manufacturer recommendations to know how much torque to apply to the rotor’s hardware.

Step 8: Reattach the Front Wheel

Finally, to complete your rotor upgrade, you must reattach the front wheel. Again, check specifications before installing the wheel to be sure you have applied sufficient torque. Then, wipe down the rotor with a cleaning solution. Either an alcohol-based or acetone-based cleaner works. If you regularly work with acetone, though, you must be careful about making contact with rubber seals. That is, acetone can be hard on your bike’s rubber components. If you contaminate rubber with acetone, you may shorten the useful life of seals and other essential parts. 

After you have finished your rotor upgrade, you can take your bike for a spin. When you do, give some time for your new rotors and brake pads to settle into place. That is, avoid aggressive riding until your new rotor gets used to its new home. 

Whether you want to keep your bike’s stock rotor or need to know how to install a Galfer oversized brake rotor kit, you are likely looking for ways to improve your bike’s braking performance. One easy way to make enhance braking potential is to upgrade your stock brake lines. Put simply, modern brake lines often offer superior performance. With top-quality components from the best brands in the business, you can’t lose when you work on your bike’s braking system.
