Do your bike’s hydraulic brakes seem to have lost their stopping power You’re not alone. This is a common problem that can be frustrating and even dangerous. But don’t worry, I’m here to help. In this guide, I’ll walk you through the steps to troubleshoot and repair your hydraulic brakes so that you can get back to riding safely and smoothly.
Most Common Reasons: Bike Hydraulic Brakes Not Working
Most Common Reasons: Bike Hydraulic Brakes Not Working
Air in the brake lines:
This is the most common cause of hydraulic brake failure. Air can enter the brake lines through a damaged or loose brake hose, or by bleeding the brakes incorrectly. Air in the brake lines causes the brakes to feel spongy and unresponsive. To fix this problem, you will need to bleed the brakes.
Brake fluid contamination:
Brake fluid can become contaminated with water, oil, or other fluids. This can cause the brakes to become sluggish and ineffective. To fix this problem, you will need to flush the brake lines and replace the brake fluid.
Brake pads worn out:
Brake pads wear out over time and need to be replaced regularly. Worn out brake pads can cause the brakes to squeal, make a grinding noise, or fail to stop the bike. To fix this problem, you will need to replace the brake pads.
Brake rotors damaged:
Brake rotors can become warped or damaged over time. This can cause the brakes to make a grinding noise, or to pull to one side. To fix this problem, you will need to have the brake rotors replaced.
Brake calipers misaligned:
The brake calipers can become misaligned over time, which can cause the brakes to drag or to pull to one side. To fix this problem, you will need to have the brake calipers adjusted.
Brake lever stuck:
The brake lever can become stuck due to a damaged or worn-out brake cable, or by dirt or debris in the brake housing. To fix this problem, you will need to clean and lubricate the brake housing, and replace the brake cable if necessary.
How to Troubleshoot: Bike Hydraulic Brakes Not Working
Symptoms of Hydraulic Brakes Not Working
There are a few different symptoms that can indicate that your hydraulic brakes are not working properly. These include:
The brakes feel spongy or unresponsive:
When you apply the brakes, they should provide a firm, consistent feeling. If they feel spongy or soft, it means that the brake fluid is not flowing properly through the system.
The brakes make a squealing or grinding noise:
This noise is usually caused by the brake pads rubbing against the rotors. It can indicate that the brake pads are worn out or that the rotors are dirty.
The brakes are not stopping the bike as well as they used to:
This is a sign that the brakes are not providing enough braking power. It can be caused by a number of factors, including low brake fluid, worn out brake pads, or dirty rotors.
Troubleshooting Hydraulic Brakes Not Working
If you are experiencing any of the symptoms listed above, you should troubleshoot your hydraulic brakes to determine the cause of the problem. Here are a few things you can check:
Check the brake fluid level:
The brake fluid reservoir is usually located on the top of the brake caliper. If the fluid level is low, you will need to add more fluid to the reservoir.
Inspect the brake pads:
The brake pads are located inside the brake caliper. You can check the brake pads for wear by looking at the thickness of the pad material. If the pads are worn down to the wear indicators, they will need to be replaced.
Clean the rotors:
The rotors are the metal discs that the brake pads rub against. If the rotors are dirty, they can cause the brakes to squeal or make a grinding noise. You can clean the rotors by using a brake cleaner and a clean rag.
How to Fix Bike Hydraulic Brakes Not Working
Once you have determined the cause of the problem, you can fix your hydraulic brakes. Here are a few tips:
Add brake fluid:
If the brake fluid level is low, you will need to add more fluid to the reservoir. Use the same type of brake fluid that is specified in your bike’s owner’s manual.
Replace the brake pads:
If the brake pads are worn out, you will need to replace them. Make sure to use the same type of brake pads that are specified in your bike’s owner’s manual.
Clean the rotors:
If the rotors are dirty, you will need to clean them. Use a brake cleaner and a clean rag.
Preventing Hydraulic Brakes from Not Working
You can help prevent your hydraulic brakes from not working by following these tips:
Inspect your brakes regularly:
Check the brake fluid level and the condition of the brake pads and rotors regularly. This will help you catch any problems early on and prevent them from becoming worse.
Don’t overtighten the brake levers:
Overtightening the brake levers can damage the brake system. Only tighten the brake levers until they are snug.
Don’t ride your bike through deep water:
Riding your bike through deep water can contaminate the brake fluid. If you ride your bike through deep water, you should flush the brake fluid and bleed the brakes.
By following these tips, you can help keep your hydraulic brakes working properly and ensure that you have safe and reliable braking.
