How do bike brakes work?
Bike brakes work by applying friction to the wheels, which causes them to slow down or stop. There are three main types of brakes on modern bikes: disc brakes, rim brakes, and V-brakes. The common bicycle brake system consists of a mechanism for applying rider force into the system, a mechanism for transmitting that force, including cables and hydraulic hoses, and a braking mechanism such as a caliper.
In rim brakes, the brake caliper is operated by a brake cable running through the frame and attached to a brake lever on either side of the handlebars. When a rider pulls on a brake lever, it forces both sides of the brake pads against the wheel rim, which is how the wheels are prevented from turning.
No matter the type of brake you have, itโs important to maintain and adjust bike brakes regularly to ensure they are functioning properly and safely.
Disc brakes work in a similar way, but the braking mechanism is located at the center of the wheel instead of on the rim. When the rider applies the brakes, the brake pads squeeze a rotor that is attached to the wheel hub, causing the bike to slow down or stop.
V-brakes are a type of rim brake that uses a longer brake arm and a curved brake pad to increase the braking force. They are commonly found on mountain bikes and hybrid bikes and work by pulling the brake cable, which causes the brake pads to grip the rim and slow down the bike.
No matter the type of brake you have, itโs important to maintain and adjust bike brakes regularly to ensure they are functioning properly and safely.

How to tune up your bike brakes
It is essential to tune up your bike brakes regularly to ensure they are functioning correctly and safely. Over time, brake pads wear out, brake cables become loose or frayed, and brakes can become misaligned, which can lead to reduced braking power or even brake failure.
Regular tune-ups can identify and address these issues before they become serious problems. Hereโs an easy step-by-step list of how to tune up your bike brakes:
1. Check your brake pads
Inspect your brake pads for wear and tear. If they are worn down to the indicator line or less than 3 mm, they need to be replaced.
2. Clean your brake pads and rims
Use a cloth and rubbing alcohol to clean your rims and a clean, dry cloth to clean your brake pads.
3. Adjust your brake pads
Loosen the nut on the back of the brake pad and align it with the rim of your tire. Tighten the nut and repeat the process for the other brake pad.
4. Check your brake cables
Check your brake cables for signs of wear and tear. If there are any frayed cables, they need to be replaced.
5. Lubricate your brake cables
Apply a small amount of lubricant to the cables and work it in by squeezing the brake lever a few times.
6. Adjust your brake cables
Loosen the nut on the cable and pull it tighter, then tighten the nut. Repeat for the other brake cable.
7. Test your brakes
Squeeze the brake levers and make sure your bike stops smoothly and quickly. Adjust your brakes as necessary.
Remember, if youโre not comfortable tuning up your bike brakes, itโs always best to take your bike to a professional bike mechanic.
How to adjust the brakes of your fixie bike?
Fixie bikes, also known as fixed-gear or single-speed bicycles, typically use either caliper rim brakes or disc brakes. Hereโs how to adjust each type of brake on your fixie bike:
Caliper Rim Brakes
1. Check brake pad alignment
Squeeze the brake lever and observe how the brake pads contact the rim. They should be parallel to the rim and not touch the tire. If they are not properly aligned, loosen the brake pad bolt, adjust the padโs position, and retighten the bolt.
2. Adjust brake cable tension
If the brake lever feels too loose or too tight, youโll need to adjust the cable tension. Locate the barrel adjuster (usually near the brake lever or caliper). Turn it counterclockwise to increase tension (for a tighter feel) or clockwise to decrease tension (for a looser feel). Test the brake lever and readjust as needed.
3. Center the brake caliper
If one brake pad is closer to the rim than the other, youโll need to center the caliper. Some caliper brakes have a small centering screw to adjust the caliperโs position. If not, you can manually center it by loosening the main mounting bolt, adjusting the caliper, and retightening the bolt.
4. Adjust the brake lever reach
If you want to change the distance between the brake lever and the handlebar, look for a reach adjustment screw on the brake lever. Turning the screw adjusts the reach to your preference.
Disc Brakes
1. Check brake pads for wear
Inspect the brake pads for wear and replace them if necessary.
2. Align the brake caliper
Loosen the caliper mounting bolts slightly. Squeeze the brake lever firmly to center the caliper over the rotor. While holding the lever, tighten the mounting bolts to secure the caliper in place. Release the brake lever and check for rotor rubbing. If rubbing persists, repeat the process.
3. Adjust brake cable tension (mechanical disc brakes)
If the brake lever feels too loose or too tight, adjust the cable tension using the barrel adjuster (located near the brake lever or caliper). Turn it counterclockwise to increase tension or clockwise to decrease tension. Test the brake lever and readjust as needed.
Always test your brakes after making any adjustments to ensure they are functioning properly and provide adequate stopping power.
4. Bleed hydraulic disc brakes (if necessary)
If you have hydraulic disc brakes and the brake lever feels spongy, you may need to bleed the brake system to remove air bubbles. This process can be more complicated and may require specific tools and brake fluid, so consult your brake manufacturerโs instructions or visit a local bike shop for assistance.
5. Adjust the brake lever reach
Some brake levers have a reach adjustment screw. Adjust the screw to change the distance between the brake lever and the handlebar to your preference.
Always test your brakes after making any adjustments to ensure they are functioning properly and provide adequate stopping power.
How to replace the brake pads of your fixie bike?
Replacing brake pads on your fixie bike is important for maintaining effective braking performance. The process may vary slightly depending on the type of brakes your bike has, but here are the general steps for both caliper rim brakes and disc brakes:
1. Gather tools and supplies
Youโll need new brake pads compatible with your bike, an Allen wrench (typically 5 mm) or a wrench for nutted brake pads, and possibly a small flathead screwdriver.
2. Remove the old brake pads
Release the brake caliper by unhooking the brake cable or using the quick-release mechanism. Use the Allen wrench to loosen the bolt or nut that secures the brake pad. Remove the old brake pad, paying attention to the orientation and any washers or spacers.
3. Install the new brake pads
Insert the new brake pad in the same orientation as the old one, making sure any washers or spacers are in the correct positions. Tighten the bolt or nut, but donโt fully secure it yet, as youโll need to adjust the padโs position.
4. Align the new brake pads
Squeeze the brake lever to bring the pads in contact with the rim. Ensure the pads are parallel to the rim and not touching the tire. Hold the pad in the correct position and tighten the bolt or nut to secure it. Repeat the process for the other brake pad.
5. Check brake performance
Reconnect the brake cable or engage the quick-release mechanism. Squeeze the brake lever to test the braking performance, and adjust the brake cable tension if necessary.
