Why Do Bike Brakes Squeak? (Explained!)

“Why are my bike brakes squeaky?” This is a question that I often hear. There are numerous reasons why brakes squeak and this article will explain what causes squeaks, how to eliminate them, and the possibility of causing harm to your bike should you take these options into action.

Why Do Bike Brakes Squeak?

The first step in fixing your squeaky brakes is to identify the source of the problem. Is it a loose component or contamination?

Squeaking brakes can be caused by a number of things, but for most cyclists, the culprit will be one of two things: vibration and a lack of grip on the rotor or rim.

Loose parts can cause vibrations that make your brakes squeak. If you’ve recently checked your brake pads and they’re still in good shape, but they’re still squeaking, take off one of the pads and spray some WD-40 or another lubricant onto it. Then slide it back into place and see if that makes a difference. You may also need to check your brake levers for play and tighten them up if necessary.

Contamination can also be an issue. If you don’t clean your bike after each ride, dirt and grime can build up between your pads and rotors or rims, causing them not to fit together as tightly as they should. This could result in noise when applying pressure during braking (especially when wet). If you’ve ruled out these possibilities, then the next step is to have a professional take a look at your brakes. However, before you do this, make sure that your bike is properly adjusted so it’s not rubbing against anything else on the road or trail.

Is it normal for new bike brakes to squeak?

Yes, it is. It is called bedding in. The new brake pads need to be worn in by riding the bike.

When a new set of brake pads are put on they will squeak as they wear in. This may take a few rides or it could take months depending on how much you use them and how often you clean your rims.

Bedding in is a normal process and requires riding the bike with the new brake pads installed until they stop squeaking.

If you have never changed your brake pads before, it is important to be aware of the wear on your rim. When new brake pads are first installed they will rub against the rim of your wheel causing a squeaking sound.

This can be alarming at first but is completely normal and will stop within a few minutes or rides as the new brake pads wear in.

Will WD40 stop bike brakes from sqeaking?

Yes, WD-40 will work on your brakes. However, you should only use it as a temporary fix because it does not lubricate the moving parts of your brakes like oil would. Instead, it just gets between them so they can move more easily against each other without making noise.

The problem with using this method is that once you start using your bike again regularly, the squeaks will return because there isn’t enough oil in there to keep things moving smoothly.

How do I stop my bike brakes from squeaking?

If your brakes squeak, it can be a real nuisance. Fortunately, there are some simple fixes that will stop the noise and get you back to enjoying your ride.

How do I stop my bike brakes from squeaking?

The first thing to try is lubricating the brake pads. This is an easy fix that often works well with older bikes (but not so much with newer ones). The brake pads are made of friction material that wears down as you use them.

When they wear down, they get thinner and make more noise as you pedal. Lubricating them with a little bit of oil or grease will make them quieter and last longer.

If this doesn’t work, it could mean that there’s a problem with the caliper itself or that the pads need replacing (depending on whether you have rim brakes or disc brakes).

If so, take your bike into a shop and have them look at it for you — but don’t worry too much about this happening unless you ride very frequently over very long distances in bad weather conditions!

If your brake pads have been installed correctly, they shouldn’t need any adjustment — but if they are worn out, they might be rubbing against the rims. If that’s the case, you can either replace them with new ones or take them off and sand them down so they don’t rub anymore.

To prevent squeaking in the future, regularly check for rust on your rims and clean it off before it has a chance to spread.


The brakes on your bike are an important part of your safety and comfort, and keeping them in good condition is essential for optimal performance. If you’re not sure how to do this, don’t hesitate to check out some videos or tutorials online — they can be very helpful!
