Bicycle brakes squeak - causes, solutions and tips for permanently quiet brakes
A squeaky bicycle can quickly spoil the fun – especially if the brakes are squeaking and attracting everyone's attention every time you slow down. But don't worry: in most cases, the problem can be solved with simple measures. This article explains why bicycle brakes squeak, how to fix the problem, and how to prevent it permanently.

Why does the bicycle brake squeak?
When a bicycle brake squeaks, the noise is caused by vibrations between the brake pad and the rim or brake disc . These vibrations become audible – often as a high-pitched squeal.
The most common causes:
1. Contaminated braking surfaces
Oil, grease, or dirt on the rim or brake disc are the main cause. Even the smallest residues can lead to noise.
Typical triggers:
Chain oil or lubricant
Street dirt
Brake dust
2. Brake pads that are worn down or glazed
Brake pads can "glaze over" over time. This causes the surface to become hard and smooth – braking performance decreases and squealing increases.
3. Wet conditions
Squeaking brakes can occur temporarily in rain or high humidity. Rim brakes are particularly affected.
4. Incorrectly adjusted brakes
If brake pads do not sit correctly on the rim or disc, uneven forces are created – and thus noise.
5. Inferior or unsuitable brake pads
Cheap or unsuitable brake pads can squeak more quickly, especially under heavy load.
Bicycle brakes squeak – what to do?
The good news: You can often solve the problem yourself. Here are the most effective measures:
✅ 1. Clean brakes thoroughly
Here's how:
Clean rims or brake discs with alcohol (isopropanol).
Use a clean, lint-free cloth
Do not use oil-based cleaners!
👉 Tip: Lightly sand the brake pads (with fine sandpaper) to remove deposits.
✅ 2. Adjust brake pads correctly
When using rim brakes, you should pay attention to the so-called toe-in position :
The front part of the brake pad contacts the rim slightly earlier than the rear part.
This reduces vibrations.
✅ 3. Change brake pads
If the brake pads are heavily worn or glazed, often the only solution is replacement.
Signs:
Glossy surface
Poor braking performance
Persistent squeaking despite cleaning
✅ 4. Check brake discs (for disc brakes)
Have they moved away?
Are they dirty or oily?
👉 If in doubt, have it cleaned or replaced.
✅ 5. Properly break in the brakes
New brake pads need to be "broken in":
Here's how it works:
Perform several controlled braking maneuvers from medium speed
No emergency braking at the beginning
Goal: uniform material transfer
Differences: Rim brake vs. disc brake
Rim brakes
More frequently affected by dampness
Squeaking often occurs when the settings are incorrect.
Easier to maintain
disc brakes
Sensitive to oil and grease
Louder squeaking when dirty
Improved braking performance in all weather conditions
Prevention: How to avoid squeaky brakes
These tips will help prevent your bicycle brakes from squeaking in the first place:
Clean regularly
Carefully lubricate the chain (do not spray on the brakes!).
Use high-quality brake pads
Adjusting brakes correctly
Store bicycle in a dry place
Specifically for e-bikes: Pay attention to the higher load.
E-bikes, due to their higher weight and speed, exert greater forces on the brakes. This can contribute to squeaking.
👉 Therefore, you should:
Use high-quality brake pads
Perform regular maintenance
Check brakes more frequently
Especially with modern e-bikes - such as the models from MYVELO - high-performance braking systems are used, which, with proper maintenance, work reliably and quietly.
Conclusion: Squeaking is usually easy to fix.
Squeaking bicycle brakes are annoying, but rarely a serious problem. In most cases, it's due to dirt, incorrect adjustment, or worn brake pads.
With a little care, regular maintenance and the right techniques, you can quickly restore smooth and reliable brakes – and thus more safety and driving pleasure.
