How to Check Your Brake Pads

Two-minute check that prevents brake failure

Quick answer

Look at how much pad material is left. Most brake makers say replace disc pads at about 1 mm. Rim pads have wear lines. Check every month.

Try this first

Free, and each takes under 5 minutes.

  1. Disc brakes: look into the caliper
  2. Rim brakes: check the wear lines
  3. Listen for grinding

In plain English

E-bikes are heavier and faster than normal bikes, so their pads wear faster. Worn-out pads stop poorly and can ruin the rotor if the metal backing touches it. Checking takes two minutes.

Step-by-step checklist

Work from the top. Steps go from free and easy to shop jobs. Switch the bike off before touching any connector. Tick each step as you go. Your progress is saved on this device.

When it's time for a shop: if you've worked through every step and the problem is still there, take the bike to an e-bike shop. Bring your notes on when it happens, plus the code.
