Properly functioning brakes are essential for a safe and enjoyable cycling experience. One crucial aspect of brake maintenance is ensuring the brake cables are in good condition and properly adjusted. Over time, brake cables can become worn, frayed, or damaged, leading to poor braking performance and potentially causing accidents. Cutting and replacing brake cables is a relatively simple process that can be done at home with the right tools and some basic knowledge.
Overview
This guide will walk you through the step-by-step process of cutting bicycle brake cables. We will cover the necessary tools and materials, how to measure and mark the cable, and the proper techniques for cutting and installing the new cable. By the end of this guide, you will have the confidence and skills to cut and replace your bicycle brake cables like a pro.
What You’ll Need
In this guide, we will assume you have a basic understanding of bicycle maintenance and have the necessary tools and materials. If you’re new to bicycle maintenance, don’t worry – we’ll provide a list of the necessary tools and materials needed to complete the task.
How to Cut Bicycle Brake Cable: A Step-by-Step Guide
As a cyclist, you understand the importance of properly functioning brakes. One crucial component of your brake system is the brake cable. Over time, the cable can become worn out, rusty, or damaged, requiring replacement. Cutting a new brake cable to the correct length can be a daunting task, especially for beginners. In this article, we will guide you through the process of cutting a bicycle brake cable, providing you with the necessary steps, tools, and tips to ensure a successful outcome.
Tools and Materials Needed
To cut a bicycle brake cable, you will need the following tools and materials:
- Cable cutters or diagonal cutters
- Cable strippers (optional)
- New brake cable
- Brake cable housing
- Brake caliper or brake lever
- Ruler or measuring tape
- Pliers (optional)
Measuring the Brake Cable
Before cutting the brake cable, you need to measure the correct length. This is crucial to ensure proper brake function and to avoid any safety issues. Here’s how to measure the brake cable:
Method 1: Measuring the Old Cable
If you have the old brake cable, you can use it as a reference to measure the new one. Remove the old cable from the brake caliper or brake lever, and stretch it out to its full length. Measure the length of the cable from the anchor point (where the cable attaches to the brake caliper or brake lever) to the end of the cable. Take note of this measurement.
Method 2: Measuring the Brake Cable Housing
If you don’t have the old cable, you can measure the brake cable housing instead. Remove the cable housing from the brake caliper or brake lever, and stretch it out to its full length. Measure the length of the housing from the anchor point to the end of the housing. Add 1-2 inches (2.5-5 cm) to this measurement to account for the cable’s inner diameter and any potential stretch.

Cutting the Brake Cable
Now that you have the correct measurement, it’s time to cut the brake cable. Follow these steps:
Step 1: Strip the Cable Insulation
If your new brake cable has insulation, you’ll need to strip it back to expose the inner wire. Use cable strippers to remove the insulation, taking care not to damage the inner wire. If your cable doesn’t have insulation, skip this step.
Step 2: Cut the Cable
Use cable cutters or diagonal cutters to cut the brake cable to the measured length. Make sure to cut the cable at a 45-degree angle, as this will help prevent the cable from fraying and make it easier to install.
Step 3: Deburr the Cable
After cutting the cable, use a file or sandpaper to deburr the cut end. This will help prevent the cable from scratching or damaging the brake caliper or brake lever.
Installing the Brake Cable
Once you’ve cut the brake cable, it’s time to install it. Here’s a brief overview of the installation process:
Step 1: Thread the Cable (See Also: Are Dot 3 And Dot 4 Brake Fluid Compatible)
Thread the cut end of the brake cable through the brake caliper or brake lever, making sure it’s properly seated.
Step 2: Attach the Cable
Attach the brake cable to the anchor point, making sure it’s securely fastened. Use pliers to tighten any bolts or nuts.
Step 3: Adjust the Brakes
Adjust the brakes to ensure proper function. Check the brake pads for wear and adjust the brake caliper or brake lever as needed.
Tips and Tricks
Here are some additional tips and tricks to keep in mind when cutting and installing a brake cable:
- Use a cable tension gauge to ensure the correct tension.
- Apply a small amount of lubricant, such as silicone spray or cable lube, to the cable to reduce friction.
- Use a cable anchor or cable stop to secure the cable and prevent it from coming loose.
- Consider using a brake cable with a protective coating, such as a Teflon or stainless steel coating, to reduce corrosion and wear.
Common Mistakes to Avoid
Here are some common mistakes to avoid when cutting and installing a brake cable:
- Cutting the cable too short, which can cause the brakes to malfunction.
- Cutting the cable at the wrong angle, which can cause the cable to fray or damage the brake caliper or brake lever.
- Failing to deburr the cable, which can cause scratches or damage to the brake caliper or brake lever.
- Failing to properly secure the cable, which can cause it to come loose and affect brake function.
Recap and Summary
In this article, we’ve covered the steps and tools needed to cut a bicycle brake cable. By following these steps and tips, you can ensure a safe and proper brake function. Remember to measure the cable correctly, strip the insulation (if necessary), cut the cable at a 45-degree angle, deburr the cable, and install it properly. Avoid common mistakes, such as cutting the cable too short or failing to deburr it, to ensure a successful outcome.
By following these guidelines, you’ll be able to cut and install a brake cable with confidence, ensuring a safe and enjoyable ride. (See Also: How To Choose Brake Rotors)
