It’s always recommended that you check your electric bike’s braking system regularly, including a check before each ride, and to have your bike serviced every six months or so. That being so, there are also warning signs to look for that indicate your electric bike’s disc brakes need to be replaced or maintained:
If your electric bike is experiencing any of the above, you can inspect the different components of the mechanical disk brake assembly to identify where the problem may be coming from. Oftentimes you can repair or replace a piece of the assembly to avoid replacing it entirely.
Mechanical disc brakes are a system of moving parts that need to be maintained properly. Over time, part of your bike’s braking system will experience wear. That doesn’t mean you need to replace the entire system. Inspect each major competent and maintain it accordingly.
Just like on a car, electric bike brake pads will wear down over time. If there are any issues with your bike’s braking system, checking the brake pads is a good place to start. A new brake pad will be about 13mm thick. If your brake pads are 3mm thick or less, you’ll need to have them replaced. If they are still thick enough to function, they may just need a good cleaning.
Mechanical brake rotors, or discs, usually require very little maintenance. If you’re experiencing friction between the brake caliper and the rotor, check the rotor for any dirt and debris that may be on it. A good cleaning with rubbing alcohol may clear things up. You can also try realigning your brake assembly to make sure everything’s properly in place. Also, replacing your aluminum or partially plastic rotor with a stainless steel one can eliminate noises and improve performance.
Brake levers can loosen over time and accumulate dirt that impedes their motion. If it has become more difficult to squeeze the brake levers of your mechanical disc brake system, apply lubricant to the moving parts of the lever. Squeeze and release the lever continuously to see if things loosen up. Be sure to also check that your bike’s brake pads are properly aligned when the lever is fully squeezed. If the pads are too far from the rotor, they’ll need to be adjusted.
Brake cables in a mechanical disc system often experience wear and tear with use. Cables may stretch out over time, which will cause a delay in braking and require the rider to squeeze on the lever harder. Additionally, brake cables can become damaged as they are exposed to the elements. Make sure to also check the brake cable housings. Sometimes the housings will accumulate dirt or rust, impeding the cable from functioning properly.
Mechanical disc brake assemblies have rotors that come in many different sizes, from 160mm (6.299 in) to 203 mm (7.992 in) in diameter, and can influence the performance of the bike.
High-powered eBikes can reach speeds of up to 28 mph.
