Mountain bike enthusiasts know how important it is to have a well-maintained bike, as it not only ensures a smooth ride but also prevents any potential accidents. One crucial component of a bike’s braking system is the disc brake pads, designed to stop the bike by providing friction to the rotor. As these pads are exposed to wear and tear, it becomes essential to replace them periodically to maintain active and safe braking.
Replacing the disc brake pads may sound daunting for a beginner cyclist, but it is relatively simple and can be done at home with a bit of patience and the right tools. This step-by-step guide outlines how to change disc brake pads on a mountain bike, including necessary precautions and tips for a successful replacement process.
Preparing for the Disc Brake Pad Replacement
Before replacing the disc brake pads on your mountain bike, it is essential to prepare yourself and the necessary tools. You can begin by clearing a workspace that is clean, spacious, and well-illuminated. This will ensure that you have enough room to move around, access all the parts you need, and work undisturbed. Remember to lay down a clean towel or an old sheet to protect the bike’s frames and components from scratches or damages.
Next, you need to gather all the tools and equipment needed for the job. Some of the essential tools required include a set of Allen Keys, a brake piston pusher tool, a Torx wrench, and a new set of brake pads. Ensure that you have the appropriate size for your bike’s model, and it should match the old ones being replaced. Failure to use the correct size can result in poor braking performance and cause damage to your bike’s rotor and caliper. With all these preparations in place, you can proceed to replacing the old brake pads with a new set.

Removing the Old Disc Brake Pads
To start the process of changing disc brake pads on a mountain bike, the first step is to remove the old brake pads. This can be done by using a 5mm Allen wrench to remove the retaining pin or bolt that is holding the brake pads in place. It is important to keep track of these small pieces as they will need to be reinserted later.
Once the pin or bolt is removed, the old brake pads should easily slide out of the caliper. Check the brake pads for any signs of wear or damage, such as uneven wear or deep grooves. If the pads are worn down to less than 3mm, they should be replaced to ensure safe riding. It is also a good idea to inspect the brake rotor for any signs of damage or debris that could impact brake performance. By following this simple step-by-step guide, anyone can change their disc brake pads on a mountain bike and keep their bike in top condition.
Inspecting the Brake Caliper and Rotor
Inspecting the brake caliper and rotor is an important step in changing disc brake pads on a mountain bike. Before replacing the pads, you want to make sure that the brake caliper and rotor are in good working condition. Inspect the caliper for any signs of wear or damage, such as cracks or corrosion. Check the rotor for any warping or damage, such as scratches or grooves.
Next, make sure that the brake caliper is properly aligned with the rotor. This is important because if the caliper is misaligned, it can cause uneven wear on the pads and reduce their effectiveness. To check the alignment, simply look at how the pads are contacting the rotor. They should be evenly spaced and have a consistent gap between the rotor and pad. If the pads are unevenly spaced or have different gaps, adjust the caliper until they are even. Inspecting the brake caliper and rotor will ensure that your new brake pads will work properly and provide optimal performance.

Installing the New Disc Brake Pads
Installing new disc brake pads on a mountain bike is an important step in maintaining the safety and performance of your bike. Before you begin, make sure you have the right brake pads that are compatible with your specific model and that you have all the necessary tools.
To install new disc brake pads, first, locate the small metal retention clip on the side of the brake caliper. Use a small tool to remove the clip and then slide out the old brake pads from the caliper. Next, apply a small amount of brake fluid to the new pads and slide them into the caliper. Use the retention clip to hold the new brake pads in place. Finally, pump the brake lever a few times to ensure that the pads are fully engaged and that the wheel spins freely without any rubbing or friction. By following these simple steps, you can easily install new disc brake pads and keep your mountain bike in top condition.
Bedding in the New Pads
After changing the disc brake pads on your mountain bike, it is essential to bed them in properly before hitting the trails. This process allows the pads to properly mate with the rotor, providing maximum braking power and longer pad life.
To bed in your new pads, find a quiet stretch of pavement or gravel road to ride on. Begin by riding at a moderate speed and gradually squeezing the brakes several times to apply pressure to the pads. After about 10 to 15 applications, increase your speed and apply the brakes more aggressively while still being careful not to lock them up. Repeat this process several times, gradually increasing the force of your braking until you are confident in the stopping power of your new pads. Properly bedded pads will have a slight sheen on the surface and provide consistent braking power.
Adjusting the Brake Caliper and Cable Tension
Once you have successfully installed the new brake pads, it is important to adjust the brake caliper and cable tension. This will ensure that the brake pads are in the correct position and are able to exert the necessary pressure on the rotor. First, loosen the bolts that hold the brake caliper in place. Then, depress the brake lever a few times to allow the caliper to center itself on the rotor. Tighten the bolts back up, making sure the caliper is still centered.
Next, adjust the cable tension using the barrel adjuster near the brake lever. Turn the adjuster clockwise to tighten the cable and increase brake pressure, or counterclockwise to loosen the cable and decrease brake pressure. You want to find a balance between having enough pressure to stop your bike, but not so much that the brakes are difficult to engage. Test your brakes by spinning the wheel and pulling the brake lever. If the brakes are not engaging properly, repeat the process until you find the perfect tension.

Testing and Troubleshooting the New Disc Brake Pads
After successfully changing the disc brake pads of your mountain bike, it is important to test and troubleshoot to ensure that the new pads are working effectively. First, start by testing the brake lever for adequate resistance. Ensure that the brake lever is firm and responsive when pulled. Test the brake pads by applying the brakes in a controlled environment to check if they grip the rotor effectively. Check for any abnormal noises or vibrations that may indicate that the pads are not installed correctly.
If the brakes are not working effectively, try troubleshooting by re-checking the installation process of the new pads. Ensure that the pads are seated correctly and the calipers are properly aligned. If the problem persists, carefully inspect the rotor for damage. If the rotor has not been damaged and the brakes are still not working, it may be time to consider seeking professional advice. It is essential that the braking system of your mountain bike is working effectively for your safety and comfort during rides. Testing and troubleshooting the new disc brake pads is a crucial final step to ensure the continued function of your bike’s crucial safety features.
Final Verdict
Changing your mountain bike disc brake pads is a straightforward process that doesn’t require a lot of know-how. With a little bit of patience and a few basic tools, you can save money and prolong the life of your bike’s braking system by maintaining it on your own. Always double-check and test your work to ensure that your brakes are functioning correctly before taking your mountain bike out for a ride.
Remember to be cautious and thorough when handling your bike’s brake system and to always wear appropriate protective gear. This guide provides a great starting point, but nothing beats hands-on experience. Don’t be afraid to experiment and try different techniques until you find what works best for you. With time and practice, changing disc brake pads on a mountain bike will become second nature, and you’ll be able to master this essential skill with ease.
