The brake lever is crucial in bringing your bike to a safe stop, making it a critical component that requires attention. In this article, we will guide you through the process of changing the brake lever on a mountain bike step-by-step. Whether you are a seasoned rider or a newbie, with the right set of tools and a little patience, you can easily replace your brake lever and have your bike in top condition.

Key Takeaway
To change the brake lever on a mountain bike, first disconnect the brake cable from the old lever. Then, remove the old brake lever from the handlebar.

Finally, test the brakes to ensure they are operating properly before going on a ride.

Tools Needed to Replace a Mountain Bike Brake Lever

Replacing a brake lever on your mountain bike is not a difficult task if you have the right tools and know-how. Before you start the replacement process, make sure you have the necessary tools. These tools will depend on the type of brake system your bike has.

If you have a hydraulic brake system, then you will need a bleed kit, hydraulic oil, a 5mm Allen wrench, and a set of pliers. For a mechanical brake system, you will need a set of Allen wrenches, a pair of cable cutters, a Phillips screwdriver, and a 10mm box wrench. Additionally, a rag or towel will come in handy to keep your work area clean and prevent any damage to the bike’s surface.

Removing the Old Brake Lever from a Mountain Bike

Before you can install a new brake lever on your mountain bike, you need to take the old one off. To do this, you will need a few tools, including a hex wrench and pliers.

First, locate the bolt that is holding the brake lever in place. It is usually located near the pivot point of the lever, on the underside of the handlebar. Use the hex wrench to loosen the bolt. Once it is loose, you can remove the bolt completely and slide the brake lever off the handlebar. If the lever is still attached to the cable, use the pliers to remove the cable from the lever. Place the old lever and any associated hardware in a safe place in case you need to reference it later. With the old brake lever removed, you can move on to installing the new one.

Installing the New Brake Lever on a Mountain Bike

Installing a new brake lever on a mountain bike can be a relatively simple process with the right tools and a bit of patience. Before installing the new lever, make sure to carefully remove the old lever by unscrewing the mounting bolt and disconnecting the cable. Once you have removed the old lever, inspect the cable for wear and tear and replace it if necessary.

Once you have inspected and replaced the cable if needed, attach the new brake lever to the handlebar using the mounting bolt. Make sure to tighten the bolt securely, but be careful not to over-tighten as this can damage the handlebar. Once the new lever is in place, reattach the cable to the lever and tighten the cable clamp bolt. Finally, adjust the cable tension and test the brakes to ensure they are working properly.

To test your new brake lever, start by squeezing it a few times to ensure that it feels comfortable to use. Next, take the bike for a test ride and adjust the brake pads if necessary. Try braking with different levels of force to see how responsive it is, and make sure that the new brake lever doesn’t require excessive force to stop the bike. If you encounter any issues, make the adjustments accordingly until you’re satisfied with the brake’s performance. It’s also crucial to note that you should test your brake lever regularly for optimum performance. By doing so, you ensure a smooth and safe ride on the trails.
