How to cut brake cable housing?

Brake cable housing is an essential component of your bike’s braking system. Occasionally, you may need to cut the brake cable housing to replace it or make adjustments. But how exactly do you go about doing this? In this article, we will provide you with a step-by-step guide on how to cut brake cable housing properly.

How to cut brake cable housing?

Cutting brake cable housing is a relatively straightforward process. To cut the housing, follow these steps:

1. **Gather the necessary tools**: Before you begin, ensure you have the required tools – a cable housing cutter or a sharp pair of cable cutters, a marker, and a measuring tape or ruler.

2. **Mark the desired length**: Use a marker to make a clear and visible mark indicating the length of housing you wish to cut.

3. **Secure the housing**: If the housing is not attached to the bike, place it in a vise or clamp it between two wooden blocks to keep it steady.

4. **Protect the surface**: To avoid scratches or damages to the housing, consider wrapping a rag or electrical tape around the area where you’ll be cutting.

5. **Cut the housing**: Using a cable housing cutter or a sharp pair of cable cutters, position the tool over the marked spot and apply even pressure to make a clean and precise cut.

6. **Smooth the edges**: After cutting, check the edges for any roughness. If needed, use a file or sandpaper to smoothen the cut edges.

7. **Remove any debris**: Finally, clear away any debris or leftover plastic shavings from the housing to ensure smooth cable movement.

Now that you know how to cut brake cable housing, let’s address some commonly asked questions related to this topic:

FAQs:

1. Can I use regular scissors to cut brake cable housing?

Regular scissors may not be strong or sharp enough to cut through the tough outer casing of the brake cable housing. It is best to use cable cutters specifically designed for this purpose.

2. Do I need to remove the cables before cutting the housing?

It is not necessary to remove the cables before cutting the housing. However, for ease of cutting and to prevent damage, ensure the cable is fully extended to minimize tension.

3. How can I measure the correct length of housing?

Measure the length of the old housing or use a measuring tape to determine the appropriate length required for replacement. Alternatively, consult a bike mechanic or refer to the bike’s manual for specifications.

4. Can I reuse the old housing?

While it is possible to reuse the old housing if it is still in good condition, it is generally advised to replace it along with the cables to ensure optimal performance.

5. Are there any safety precautions I should take?

When cutting the brake cable housing, it is essential to protect your eyes from any flying debris. Consider wearing protective goggles or safety glasses to prevent eye injuries.

6. What can I do if I accidentally cut the housing too short?

If you cut the housing shorter than desired, you will need to replace it with a new piece of housing. Take precise measurements or consult a professional to ensure you purchase the correct length of housing.

7. Do I need any lubrication after cutting the housing?

After cutting the housing, applying a light lubricant or grease to the inner cable and the new housing’s cut ends can help ensure smooth cable movement and reduce friction.

8. Are there any alternatives to a cable housing cutter?

If you don’t have a cable housing cutter, you can use a Dremel tool with a reinforced cutting disc or carefully use a hacksaw. However, exercise caution to avoid damaging the housing or inner cables.

9. Should I replace the inner cable at the same time?

While not necessary, it is often recommended to replace both the housing and inner cable simultaneously for optimal performance and to ensure they are both in good condition.

10. Can I use a file to cut the housing?

Using a file to cut the housing is not recommended. A file may create jagged edges and compromise the integrity of the housing.

11. How often should I replace the brake cable housing?

The frequency of replacing brake cable housing depends on various factors such as usage, environment, and signs of wear. Generally, it is advisable to inspect the housing regularly and replace it if you notice any cracks, kinks, or signs of damage.

12. Can I reuse cable ends after cutting the housing?

It is possible to reuse cable ends if they are still in good condition. However, it is recommended to install new cable ends to ensure a secure and reliable connection between the cable and the brake mechanism.

Now that you have learned how to cut brake cable housing and have gained some additional insights, you can confidently perform this task when necessary. Remember to follow the steps carefully and prioritize safety throughout the process.
