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.
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.
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.
