Also called: disc pads
What it does
E-bikes wear pads faster than regular bikes because they're heavier and faster.
Signs of a problem
- Grinding or scraping
- Brakes weaker than before
- Squealing
Safe things to check
- Look into the caliper: if there's very little pad material left, have them replaced.
- Grinding metal-on-metal: stop riding; that damages the rotor.
Looking after it
- Pads contaminated with oil usually need replacing, not cleaning.
