Few e-bikers have heard of curing, bedding in, or breaking in new brake pads, and not all bike shops want to talk about it. The reason is simple: It takes time to bed or cure brake pads, and time is money.
How it Works!
To bed in pads, simply e-bike to a speed of 18.5 mph (30 km/h) in a safe area without traffic and come to a complete stop. Don't skid the tires; repeat this process at least 30 times in 15 minutes.
Few bike shops can afford staff to bike for 10-15 minutes to perform a correct bedding procedure. Uncured brake pads are also not as durable as correctly bedded brakes, possibly generating more sales for bike shops as the pads need to be replaced more frequently.
A Simple Procedure Improves Durability and Breaking Power
Minor imperfections on the rotor and the pads affect the performance of brakes resulting in squeaking noises and reduced stopping power. Correctly bedded pads significantly improve the brakes' performance as they last substantially longer and brake better.
According to Magura, a leading high-quality Italian brake manufacturer, bedding brake pads is a straightforward but essential process. When brakes are bedded, the imperfections are removed, the rotor and pads are fine-tuned, and an optimal friction surface is created between the pads and rotors.
It also removes any residue from the manufacturing process from the brake pads. New brake pads and rotors only reach their full potential during the break-in period.
Ask the bike shop if they have bedded new brakes so you know if you need to do it yourself!
