So whether you’re a seasoned cyclist or a new rider, read on for all the information you need to know about fixing new bike brakes.
Why New Bike Brakes Not Working
Insufficient pad contact
The brake pads are not close enough to the rim to create friction.
This can be caused by:
Improper installation of the brake pads
Worn-out brake pads
Bent brake rotors
Air in the brake lines
Air in the brake lines prevents the brake fluid from flowing freely, which reduces braking power.
This can be caused by:
Loose brake bleed screws
Damaged brake lines
Improper bleeding of the brakes
Brake lever adjustment
The brake levers may be adjusted incorrectly, which can cause the brakes to be too weak or too strong.
This can be caused by:
Improper adjustment of the brake levers
Damaged brake levers
Brake cable stretch
Brake cables stretch over time, which can cause the brakes to become less effective.
This can be caused by:
Frequent use of the brakes
Exposure to extreme temperatures
Poor quality brake cables

Troubleshooting
If your new bike brakes are not working, there are a few things you can check to troubleshoot the problem.
Check the brake pads:
Make sure that the brake pads are properly installed and that they are not worn down to the point where they can no longer make contact with the rim. If the brake pads are worn down, you will need to replace them.
Check the brake cable:
Make sure that the brake cable is properly adjusted and that there is no damage to the cable. If the brake cable is damaged, you will need to replace it.
Check the brake lever:
Make sure that the brake lever is properly adjusted and that it is not sticking. If the brake lever is sticking, you will need to clean and lubricate it.
Check the brake fluid:
If your bike has hydraulic brakes, make sure that the brake fluid level is correct. If the brake fluid level is low, you will need to add more brake fluid.
Fixing
Once you have troubleshooted the problem, you can fix your new bike brakes.
To replace the brake pads, follow these steps:
1. Remove the wheel from the bike.
2. Remove the brake caliper from the frame.
3. Remove the old brake pads.
4. Install the new brake pads.
5. Reinstall the brake caliper.
6. Reinstall the wheel.
To adjust the brake cable, follow these steps:
1. Loosen the cable adjustment bolt on the brake caliper.
2. Pull the brake lever until the pads are just touching the rim.
3. Tighten the cable adjustment bolt.
4. Test the brakes to make sure they are working properly.
To clean and lubricate the brake lever, follow these steps:
1. Remove the brake lever from the handlebar.
2. Spray a degreaser on the brake lever.
3. Wipe the brake lever clean with a rag.
4. Apply a light coat of lubricant to the brake lever.
5. Reinstall the brake lever.
To add brake fluid to a hydraulic brake system, follow these steps:
1. Remove the reservoir cap from the brake caliper.
2. Add brake fluid to the reservoir until it reaches the fill line.
3. Replace the reservoir cap.
By following these steps, you can troubleshoot and fix your new bike brakes.
Prevention
To prevent your new bike brakes from malfunctioning, you can take the following steps:
Inspect your brakes regularly:
Check the brake pads for wear and tear, and make sure that the brake cable is properly adjusted.
Clean and lubricate your brakes regularly:
This will help to keep the brakes working smoothly and prevent them from sticking.
Be careful not to apply too much pressure to the brake levers:
This can damage the brakes and cause them to malfunction.
If you experience any problems with your brakes, have them serviced by a qualified bicycle mechanic:
This will help to ensure that your brakes are working properly and that you are safe on the road.
FAQs: New Bike Brakes Not Working
Why aren’t my new bike brakes working?
There are a few possible reasons why your new bike brakes might not be working. Here are some of the most common:
The brakes are not properly adjusted: Make sure that the brake pads are aligned correctly with the rim and that the brake cable is tensioned properly.
The brake pads are worn out: If the brake pads are worn down to the metal, they will not be able to grip the rim properly and will not stop the bike effectively.
The brake fluid is low or contaminated: If the brake fluid is low, the brakes will not have enough pressure to stop the bike. If the brake fluid is contaminated, it can cause the brakes to become spongy or ineffective.
The brake calipers are seized: If the brake calipers are seized, they will not be able to move properly and will not apply pressure to the brake pads.
The brake rotors are warped: If the brake rotors are warped, they will not be able to grip the brake pads properly and will not stop the bike effectively.
How do I adjust my new bike brakes?
To adjust your new bike brakes, you will need to follow these steps:
1. Locate the brake adjustment screws: The brake adjustment screws are usually located on the brake calipers.
2. Turn the adjustment screws clockwise to increase the brake tension or counterclockwise to decrease the brake tension:
3. Test the brakes to make sure that they are working properly:
How do I know if my brake pads are worn out?
There are a few ways to tell if your brake pads are worn out. Here are some of the most common:
The brake pads are thin: If you can see the metal backing of the brake pads, they are too thin and need to be replaced.
The brake pads are noisy: If the brakes are making a squealing or grinding noise, it is a sign that the brake pads are worn out.
The brakes are not stopping the bike effectively: If the brakes are not stopping the bike as quickly as they used to, it is a sign that the brake pads are worn out.
How do I bleed my new bike brakes?
To bleed your new bike brakes, you will need to follow these steps:
1. Locate the bleed port on the brake caliper: The bleed port is usually a small hole with a rubber cap.
2. Attach a bleed kit to the bleed port: The bleed kit will include a hose, a reservoir, and a pump.
3. Open the bleed port and fill the reservoir with brake fluid:
4. Pump the lever until the brake fluid starts to flow out of the bleed port:
5. Close the bleed port and repeat steps 3-4 until the brake fluid is clear:
How do I fix seized brake calipers?
To fix seized brake calipers, you will need to follow these steps:
1. Remove the brake calipers from the bike:
2. Clean the brake calipers and rotors with brake cleaner:
3. Apply a thin coat of brake grease to the brake caliper pistons:
4. Reinstall the brake calipers on the bike:
How do I fix warped brake rotors?
To fix warped brake rotors, you will need to follow these steps:
1. Remove the brake rotors from the bike:
2. Place the brake rotors on a flat surface:
3. Use a brake rotor truing tool to true the brake rotors:
4. Reinstall the brake rotors on the bike:
