Most cyclists only think about brake pads when their bike starts to brake poorly. Braking distance lengthens, more pressure is needed on the levers on descents, or squealing and other unusual noises appear. Many cyclists continue to ride, thinking it's not serious, especially if the brakes are still working.
However, this is precisely how brake pad wear begins. And the longer you wait to change them, the more you risk losing efficiency, having to make more expensive repairs, and, worse, suffering a braking system failure. In this article, experts from Routes and Roads explain how to identify signs of brake pad wear before they are completely worn out.

Why replace your brake pads regularly
Each time you brake, the pads rub against the disc or the rim's braking surface and gradually wear down. This phenomenon is normal and affects all types of bikes, whether it's a city bike used daily in Paris, a gravel bike, or a road bike for long rides in Île-de-France.
Unlike discs or calipers, pads are designed to wear out and be replaced regularly. They absorb most of the stress during braking, thus protecting more expensive components from premature wear.
This is why they are wear parts: their condition must be checked regularly and they must be replaced in time. This simple operation helps keep brakes effective and avoids unnecessary expenses.
Regular maintenance of the braking system directly contributes to your safety
The problem is that this wear happens slowly. We get used to the changes and often only notice the problem when the brakes no longer respond as before.
To avoid unpleasant surprises, remember to regularly check the main components of your bike. You can do this at the Routes and Roads workshop: our mechanics carry out a complete bike diagnosis, assess pad wear, and check the proper functioning of the braking system. We explain in detail the process of bike care at Routes and Roads in a dedicated article.
Brake pad lifespan
Many cyclists are surprised to learn that there is no universal lifespan for brake pads. Even with identical mileage, their level of wear can vary considerably. Indeed, several factors influence their wear.
Conditions of use play an essential role. Rain, mud, and sand act as abrasives and significantly accelerate the wear of the friction material. Cyclists who ride all year round generally replace their brake pads more often than those who only use their bike in dry weather.
Sand and mud accelerate the wear of all bike components
The terrain also has an impact. On routes with many descents, brakes work harder than on relatively flat roads around Paris.
The way of braking also plays an important role. Some cyclists brake gently and early, others late and hard. The harder you brake, the faster the pads wear out.
The cyclist's weight, luggage transport, and the type of bike used also impact pad wear. A road bike generally rides on good asphalt and rarely brakes hard, a gravel bike more often encounters dust, mud, and long descents, a city bike constantly brakes at traffic lights and intersections, which leads to faster pad wear than one might imagine.
Signs of brake pad wear
In most cases, the bike sends several signals indicating that the braking system requires special attention.
Lengthening of braking distance
One of the first signs is the lengthening of braking distance. You brake as usual, but the bike slows down less effectively. This may indicate that the pad lining has become too thin to ensure optimal contact with the disc.
Loss of braking power
Another common symptom is reduced braking power. This phenomenon is particularly noticeable during long descents or in the city. If you have to press the lever harder to slow down or stop the bike, it's time to check the condition of the pads.

Unusual noises
Wear can also be accompanied by squealing, whistling, or metallic sounds. This is not always critical, but it warrants an inspection of the braking system. If these noises appear suddenly and persist after cleaning the brakes, it is best not to wait before having the bike checked.
Unpredictable braking
Another important signal is irregular braking behavior. The bike may react more or less strongly to the same pressure on the lever. At high speeds or in the rain, this lack of consistency is simply dangerous.
Risks of postponing replacement
Many cyclists wait until the last minute before replacing their brake pads, believing that the brakes are still working satisfactorily.
The problem is that the degradation of braking performance occurs gradually and often goes unnoticed. The cyclist gets used to a longer braking distance and a less effective brake response, until the difference becomes obvious.
When the pads are completely worn, their metal backing can come into contact with the disc and damage its surface. A simple and inexpensive intervention can then turn into a much larger repair of the braking system.
Regular pad checks can prevent more costly repairs
Determining wear yourself
In many cases, it is possible to assess the condition of the brake pads yourself.
Before a long ride or at the beginning of the season, a few minutes are enough to visually check the condition of the brakes. If the lining is almost completely worn, if metal is visible, or if the wear is uneven, a more thorough check is necessary.
Also listen to your bike: unusual noises, less effective braking, or different lever feel can often detect a problem before it becomes critical.
When to go to the workshop
If you find it difficult to assess the condition of the pads or if you have any doubts about the proper functioning of the braking system, it is best to entrust your bike to a reliable workshop. Replacing the pads is also an excellent opportunity to perform a more complete brake check.
For disc brakes, the mechanic checks the condition of the discs, checks for play, and ensures the proper functioning of the entire system.
If your bike is equipped with hydraulic brakes, they can also determine if a bleed is necessary. Over time, brake fluid loses efficiency and micro-air bubbles can appear in the circuit. This changes the feel at the lever and can reduce braking stability.

A complete check ensures that the entire system is ready for long rides and intensive use.
Conclusion
Brake pads rarely wear out suddenly. In most cases, the bike sends several warning signals: braking distance lengthens, unusual noises appear, or braking feel changes. By paying attention to these signs, it is possible to intervene well before wear compromises safety or riding comfort.
Regular checking of the pads' condition helps keep brakes effective, avoids unnecessary expenses, and allows you to ride with confidence. And if you have any doubts about the condition of your brakes, the specialists at Routes and Roads can perform a complete diagnosis, assess component wear, and recommend the most suitable pads for your bike.
