Bedding brake pads on your bicycle is a critical step in optimizing the performance of the braking system. This process involves transferring a thin layer of brake pad material onto the rotor’s braking surface, which ensures smoother and more consistent braking. Not only does bedding in the brake pads improve the bike’s stopping power, but it also extends the lifespan of the brake pads and rotors. In this article, we will discuss the importance of bedding in brake pads and provide a step-by-step guide on how to do it properly.
Reasons for Bedding Brake Pads on Disc Brake systems:
- Increased Performance: Bedding in the brake pads results in improved braking performance. It allows the brake pads to conform to the contours of the rotor, leading to more surface contact and better heat dissipation. This, in turn, enhances the overall efficiency of your braking system.
- Noise Reduction: New brake pads can often produce squealing or squeaking noises when applied. By bedding them in, you eliminate any inconsistencies on the pad surface, reducing noise levels and ensuring a quieter ride.
- Extended Pad and Rotor Life: Properly bedding in the brake pads prevents glazing, a common issue where the pad material hardens and reduces its effectiveness. By bedding in the pads, you establish an even transfer layer, reducing the likelihood of glazing and increasing the lifespan of both the pads and the rotors.
- Consistent Performance: Bedding in your brake pads ensures that the rider has consistent braking performance in various conditions. Whether the rider is descending a steep hill or riding in wet weather, properly bedded pads provide reliable stopping power under any circumstance.
How to Bed in the Brake Pads:
- Choose a Suitable Location: Find a quiet and safe location where you can perform the bedding process without interruptions. A flat stretch of road or an empty parking lot would be ideal.
- Clean the Rotors: Before starting the bedding process, make sure to clean your rotors with isopropyl alcohol or a dedicated rotor cleaner. This removes any contaminants that could affect the bedding process.
- Accelerate and Brake Firmly: Build up speed on the bike to around 20 km/h, then apply the brakes firmly but smoothly to reduce your speed to about 10 mph. Repeat this process 10-15 times, allowing the brakes to cool down between each stop.
- Avoid Coming to a Complete Stop: It is essential to avoid coming to a complete stop during the bedding process, as this can lead to uneven pad deposits on the rotor surface.
- Test for Consistency: Once you have completed the bedding process, test the brakes to ensure they are working smoothly and consistently. Pay attention to any signs of pulsing, grabbing, or noise, which could indicate that further bedding is required.
- Monitor Your Braking Performance: After bedding in the brake pads, pay attention to the feel and performance of your brakes during your rides. If you notice any issues such as fading, excessive noise, or decreased stopping power, re-bed the pads following the same process.
Bedding in the disc brake pads is a simple yet crucial step in ensuring optimal braking performance and longevity of the brake system. By following the steps outlined above, riders can enjoy the benefits of improved braking efficiency, reduced noise levels, and extended pad and rotor life.
