Can You Convert A Mountain Bike To Disc Brakes

Hey, mountain bikers! Have you been wondering if it’s possible to convert your beloved bike from rim brakes to disc brakes?

Well, I’m here to tell you that the answer is YES! In this article, we’ll be discussing how you can make the switch easily and affordably.

Disc brakes offer a significant upgrade over traditional rim brakes in terms of both power and modulation. They’re also much easier to maintain and don’t require adjustments as often due to their sealed nature.

So, let’s get into the details of making this conversion happen on your own bike and see what kind of improvements are in store for you!

Understanding Disc Brakes

I’ve been riding mountain bikes for a few years now, and I’m always looking to upgrade my bike with the latest technology. Recently, I decided to convert my mountain bike from rim brakes to disc brakes.

Disc brakes are much better than traditional rim brakes because they offer more control over your braking power, regardless of terrain or weather conditions.

The first step in converting my bike was understanding how disc brakes work. Unlike standard rim brakes that use brake pads against the wheel’s rims, disc brakes rely on rotors attached to the wheel hub and linked via hydraulic lines to levers at the handlebars. When you pull the lever, fluid is released from one side of the line and pushed into a piston inside the caliper near the rotor, which presses brake pads against it.

To ensure compatibility between my frame mountings and rotor sizing I had to take careful measurements before ordering new components for my conversion project. It took some research but eventually I found all of the parts needed for a successful conversion – then it was just a matter of fitting them together!

Choosing The Right Components

I’m considering converting my mountain bike to disc brakes, so I need to make sure I choose the right components.

Rotors are the large metal discs mounted to the hubs of the wheel, so I’ll need to pick the size that fits my bike.

Brake calipers are the devices that clamp onto the rotor when the brake lever is applied, so I need to make sure they are compatible with the type of brakes I’m using.

Brake levers are the parts connected to the handlebars that allow me to apply the brakes, so I’ll need to make sure they fit the diameter of my handlebars.

I’m confident that if I choose the right components, I’ll be able to convert my bike with ease.


When it comes to converting your mountain bike to disc brakes, one of the most important components are the rotors.

Not all brake rotor sizes are created equal – you’ll want to make sure that you get a size and type that is compatible with your existing setup.

For example, if you have an older style frame or fork, you may need an adapter in order to fit larger rotors.

Additionally, some frames and forks require specific sized brake pads as well.

It’s important to do research on what will work best for your particular system before making any changes.

Lastly, when selecting a brake rotor size, be sure to consider the weight of yourself and your bike – lighter riders can often get away with using smaller discs than heavier ones!

Brake Calipers

Now that we’ve discussed rotors, let’s move on to brake calipers.

They are an integral part of the braking system, and need regular maintenance just like any other component on your bike.

Brake pads will wear over time, so it’s important to keep an eye on them and replace when necessary.

It’s best to opt for quality pads as they will last longer and offer better performance.

You’ll also want to make sure that the caliper is properly aligned with the rotor – otherwise you risk uneven pad wear or reduced stopping power.

Lastly, if you’re using disc brakes it’s a good idea to invest in some brake fluid specifically designed for this type of setup as this can help ensure smooth operation and reduce noise.

Brake Levers

Now we’re onto brake levers. They play a crucial role in the braking system, and are one of the most important components when it comes to choosing the right setup for your bike.

It’s important to consider what type of brakes you’re using before selecting your lever – different systems require specific cables or rotor sizes which might not work with certain types of levers.

You’ll also want to think about how you hold your handlebars when riding as this can affect the position of the brake lever.

Lastly, make sure that whatever lever you choose is compatible with your frame and offers enough reach so that you can comfortably access them while on the move.

Installing The Brakes

I’m standing in my garage with the mountain bike propped up against the workbench. I’ve got all the parts for a disc brake conversion ready to go—brake pads, caliper and rotors. Now it’s time to get started on installing them!

First, I need to figure out what size rotor I’ll be using. Generally speaking, larger rotors are better suited for steep downhill riding or heavier riders because they provide more stopping power but require more effort from your hands when braking. After measuring the frame, I decide to go with a 180mm rotor size which will give me plenty of stopping power without being overly heavy.

Now comes the fun part: attaching everything together. First up is mounting the calipers onto the forks. This involves lining up the two holes on each side of the caliper and securing them tightly with screws before bolting on both rotors.

Then it’s onto fitting and tightening each of the brake pads into place – making sure that they sit properly within their retainers so that there’s no rubbing or sticking when you apply pressure with your fingers as you test them out afterwards.

After checking that all bolts have been tightened correctly and double-checking that everything has been connected properly, I take my newly converted mountain bike outside for its first spin around the block – feeling confident knowing that my brakes will perform perfectly in any situation!

Adjusting Brake Settings

Yes, it is possible to convert a mountain bike from rim brakes to disc brakes.

After all the hard work of installing the brakes on your bicycle and getting them tuned up, now comes the time for brake maintenance and wheel alignment.

The first step in maintaining your new braking system is checking for wear and tear on both the rotors and pads. Inspecting these regularly will ensure that neither part gets worn down too much or becomes damaged due to improper installation or adjustment.

The second step in making sure your new disc brakes are working properly is adjusting the brake settings. You can do this by manually adjusting the tension on each side until you get an equal amount of resistance when using either side of the brake handle. This process may take some trial-and-error but it’s important to make sure everything is adjusted correctly otherwise your wheels won’t be able to stop as quickly or efficiently as they should.

Lastly, if you want maximum performance out of your disc brakes then you’ll need to have proper wheel alignment done before every ride. Wheel alignment ensures that your tires are aligned with one another so that they don’t rub against each other during braking, reducing drag and improving overall efficiency.

With regular maintenance and correct adjustments, disc brakes can provide superior stopping power compared to traditional rim brakes – just remember to keep them clean!

Testing And Troubleshooting

Once you have decided to convert your mountain bike to disc brakes, it’s important that the brakes are tested and properly maintained for safety.

Testing the brake system is a good way to ensure that all components work well together so you can get the most out of them.

To start off with testing, check that the discs on the wheels are compatible with your new brake system.

You’ll want to make sure they fit snugly into place as any loose parts could cause major problems when using them while riding.

If everything looks in order, move onto inspecting and lubricating any moving parts like cables or levers associated with the braking system.

This will help reduce friction between these mechanical pieces which helps increase reaction time and overall performance of the brakes.

Additionally, keeping an eye on potential wear and tear over time can help prevent malfunctions or failure due to lack of proper maintenance.

To guarantee maximum efficiency from your brake system, regular checks should be done such as checking for air bubbles in hydraulic systems or making sure pads still have adequate material left on them before replacing them completely.

Taking care of minor issues as soon as possible can save you money down the road and keep you safe during rides!
