- What is a bike brake pad and how it works
A bicycle brake pad is a flat, rectangular-shaped component that is pressed against the rim or brake disc to generate friction and decelerate the wheel. It is made of frictional materials such as resins, metals or ceramics.
The pads are housed inside the brake caliper, which is the element that actually squeezes against the rim or disc when the brake lever is pulled. The pads are therefore the contact surface that creates friction. Over time and use they wear down to the point of requiring replacement.
The most common types of brake systems that use pads are:
- Pad brakes: the pads are placed on the sides of the rim, the caliper closes by adhering them to the rim
- Disc brakes: the pads clamp a metal disc integral with the wheel hub
- Drum brakes: the pads are inside the drum, integrated into the hub
The force applied by the lever is multiplied by the caliper system, allowing the pads to exert great pressure on the rim or disc. This creates friction and heat, dissipating kinetic energy and slowing the wheel. Proper modulation of the lever allows for precise metering of braking force.

Types of brake pads: organic, sintered and other materials
There are two main types of material for bicycle brake pads:
- Organic pads: made from natural or synthetic resins reinforced with fibers. They offer modulable braking power and good performance even in the rain. They tend to wear out faster.
- Sintered pads: contain metal powders pressed and sintered at high temperatures. They have greater power and durability, withstand moisture and mud well, but are noisier and tend to overheat.
Other materials used are:
- Semi-ceramic pads: mixture of organic material and ceramic powders. Good overall performance.
- Ceramic pads: pure ceramic powders, very high performance but fast wear.
- Metal pads: stainless steel foil, high power but poor modulability.
The choice depends on: type of bike and braking system, expected conditions of use, need for power or modulability, and sensitivity to noise. For example, disc brakes on mountain bikes require high-quality sintered pads, while quiet, soft organic pads are recommended for city bikes.
-
Differences between front and rear pads
There are generally no major differences between front and rear brake pads, since both perform the same function by generating friction on the rim or disc. However:
- The front pads are under more stress and therefore wear sooner, since the front wheel is responsible for about 70-80% of the total braking force.
- On mountain bikes, the rear pads are often slightly smaller to reduce weight.
- The material can be chosen different, such as organic rear and sintered front pads, to combine modulability in the back and power in the front.
- Sometimes the composition is slightly varied, for example with a higher percentage of metals in the front pads.
In any case, it is a good idea to replace the pads of both wheels at the same time to ensure uniform equipment and balanced performance.
-
How long do brake pads last
The service life of brake pads depends on many factors:
- Pad type: sintered pads last up to 2-3 times longer than organic pads
- Conditions of use: steep and continuous descent, mud and moisture accelerate wear and tear
- Driving style: sudden and prolonged braking overheats the pads, reducing their life
- Cyclist's weight and bike load: affect the energy to be dissipated during braking
- Maintenance and cleaning: dirty pads wear out sooner
- Type of brake system: disc brakes tend to wear out pads faster
On average, for normal use, the duration ranges from:
- Organic tablets: 300-800 km
- Sintered pads: 800-2500 km or more
It is a good idea to check the condition of the pads every 200-300 km and take action as soon as they reach the wear limit, so as not to damage discs or rims.
-
Signs that pads need to be replaced
These are the main signs that the brake pads are worn and need to be changed:
- The brake lever must be pulled closer and closer to the handlebar to achieve the same braking force
- More and more fingers are needed to pull the lever and increase the pressure
- Braking causes abnormal vibration and shaking of the handlebar or fork
- The pads appear visibly worn, with grooves or thinning
- You can hear the typical metallic sound of pads rubbing against the metal of the rim or disc
- Braking you can smell burning and see smoke from the brake system
When these signs appear, it is best not to delay replacement so as not to jeopardize safety and risk brake failure. Better safe than sorry!
-
Procedures for replacing brake pads
Replacing brake pads is simple, quick and can be done independently by following these steps:
- Lift the wheel off the ground and remove it from the fork/frame
- Open the clamp by acting on the adjustment screw or the appropriate release lever
- Remove worn pads by sliding them out of the caliper
- Clean the clamp from dirt, dust, or metal debris with a cloth
- Insert the new pads in the correct position, checking the direction
- Retighten the clamp until the pads are firmly locked in place
- Check pad alignment and clearance, adjusting if necessary
- Repeat the operation on the second wheel
- Carry out a few braking tests to verify proper operation
For perfect success, use compatible pads, lightly lubricate the sliding elements, and tighten the clamp properly.
