How to replace brake pads

Brake pads on all electric bicycles are consumable parts that gradually wear down with long-term use. When worn to a certain extent, they can affect braking performance and even pose a safety hazard.Inspecting and replacing brake pads is crucial for every rider, as it directly impacts riding safety. This article will provide detailed guidance on the specific procedures for brake pad inspection and replacement.

Preparation for Inspection and Replacement

  • Brake pad replacement
  • Allen wrench 
  • Needle-nose pliers

Disc brake pads wear down over time due to normal use. This can cause a slower brake response time and require more effort to press the brakes.

A squeaking noise from disc brakes is usually caused by contaminated brake pads. Even the slightest amount of oil, including from your skin, can damage disc brake pads. Minimize contact between the brake surface and bare skin whenever handling brake pads. If you do touch the pads, clean them with rubbing alcohol or a specialized product for disc brake pads. Then lightly sand the pads.

Brake Pad Inspection

Check your brake pads for shininess or visible wear. Inspect the pads by removing the wheel and examining the space where the rotor spins.

When inspecting brake pads, pay attention to the following key points:

  • Integrity: Ensure there are no chunks, dents, or missing parts. If there are, replace the damaged pads before your next ride.
  • Thickness: The pad material should be at least 1.5 mm thick. If you don't have a ruler, note that a grain of rice is about 1.5 mm thick (width, not length). If the pad is thinner than this, it’s time to replace it.
  • Cleanliness: The pads should be free of oil and other contaminants. If the pads are dirty, especially if they are oily (a significant safety hazard!), they need to be replaced.
