Can You Change Your Bike's Disc Brake into a Drum Brake?

If you have a bike with disc brakes and you are wondering if you can change them to drum brakes, the short answer is: no, you can't. Or at least, you shouldn't.

In this article, we will explain why changing from disc brakes to drum brakes is a bad idea, what are the differences between the two types of brakes, and how to maintain your disc brakes properly.

Why Changing from Disc Brakes to Drum Brakes Is a Bad Idea

Disc brakes are a modern and superior braking system compared to drum brakes. They provide better braking performance, improved heat dissipation, and easier maintenance. Drum brakes are an older and inferior braking system that have many disadvantages, such as lower stopping power, higher tendency to overheat and fade, and more complicated servicing.

Changing from disc brakes to drum brakes would require replacing not only the brake calipers and rotors, but also the wheel hub and possibly the swingarm and the spokes. This would be extremely expensive, time-consuming, and impractical. You would also need to find a custom machinist who can make a one-off drum for your bike, which would be very rare and costly. Moreover, you would end up with a bike that has worse braking performance, safety, and reliability.

There is no logical reason why you would want to change from disc brakes to drum brakes. It would be like downgrading your smartphone to a flip phone. Disc brakes are the standard for most bikes today, and they offer many advantages over drum brakes. If you are not satisfied with your disc brakes, you can always upgrade them with better pads, rotors, or calipers, but never switch them to drum brakes.

What Are the Differences Between Disc Brakes and Drum Brakes

Disc brakes work by using a hydraulic caliper that squeezes brake pads against a metal disc or rotor that is attached to the wheel hub. The friction between the pads and the rotor slows down and stops the wheel's rotation. Disc brakes are more efficient at converting kinetic energy into heat, which means they can stop the bike faster and more consistently. They also have better heat dissipation, which means they can resist fading and overheating. Disc brakes are easier to inspect and service, as they have fewer parts and are more accessible.

Drum brakes work by using a hydraulic wheel cylinder that pushes brake shoes out against the inside of a metal drum that is attached to the wheel hub. The friction between the shoes and the drum slows down and stops the wheel's rotation. Drum brakes are less efficient at converting kinetic energy into heat, which means they have lower stopping power and more variability. They also have poorer heat dissipation, which means they are more prone to fading and overheating. Drum brakes are harder to inspect and service, as they have more parts and are more hidden.

How to Maintain Your Disc Brakes Properly

Disc brakes are relatively easy to maintain, but they still require some regular care and attention. Here are some tips on how to keep your disc brakes in good condition:

1. Check your brake pads for wear and replace them when they are worn out or damaged. You can tell if your brake pads are worn out by looking at the thickness of the friction material or by listening for a squealing or grinding noise when braking.
2. Check your brake rotors for warping, cracking, or scoring and replace them if they are damaged or out of shape. You can tell if your brake rotors are warped by feeling for a pulsating or vibrating sensation when braking or by looking for uneven wear patterns on the surface.
3. Check your brake fluid level and quality and replace it if it is low or contaminated. You can tell if your brake fluid is low by looking at the reservoir or by feeling for a spongy or soft brake pedal. You can tell if your brake fluid is contaminated by looking for a dark or cloudy color or by smelling for a burnt odor.
4. Check your brake calipers for leaks, corrosion, or sticking and replace them if they are faulty or damaged. You can tell if your brake calipers are leaking by looking for fluid stains or drips on the caliper or rotor. You can tell if your brake calipers are corroded by looking for rust or pitting on the metal parts. You can tell if your brake calipers are sticking by feeling for a dragging or binding sensation when braking or by looking for uneven pad wear.

By following these tips, you can ensure that your disc brakes perform well and last long. Remember that disc brakes are one of the most important components of your bike's safety and performance, so don't neglect them or try to change them to drum brakes.

Conclusion

In conclusion, changing from disc brakes to drum brakes is not possible or advisable. Disc brakes are far superior to drum brakes in terms of braking performance, heat dissipation, and maintenance. Drum brakes are outdated and inferior in terms of stopping power, fading, and servicing. If you have a bike with disc brakes, you should keep them and take good care of them. If you have a bike with drum brakes, you should consider upgrading them to disc brakes..
