Why must new brakes be bedded-in?
Correctly bedding-in a brake makes a big difference. During the bedding-in phase the brake pads and rotor adjust to each other. The smallest imperfections are ironed out to create the optimal friction surface. What's more the bedding-in phase removes any remains of the manufacturing process from the brake pads. The rotor and the brake pads are only fully tuned into each other after the bedding-in phase is complete. Only then can they offer optimal performance and durability.
Rim brakes:
The different materials, surfaces and shapes of different models of rimbrake mean that we cannot make specific recommendations regarding the bedding-in phase. Therefore MAGURA recommends that the rims and brake pads be regularly checked and cleaned to remove any possible residue during the first 50 kilometers of riding.
Rotor brakes:
New brake pads and rotors only attain their final braking force during the bedding-in phase. To achieve this ride on even ground and accelerate to a speed of 30 km/h before braking to a standstill. Repeat this process at least 30 times per brake. The brake pads and rotor are now bedded-in and can perform optimally.
Please note that the larger the rotor the longer the bedding-in process may take. Larger rotors with higher mass take considerably longer to reach the required temperature needed to bed in the brake.
