How to you know when your brake pads are worn ou

When you're out on your mountain bike, there’s one thing you always need to rely on: your brakes. But how do you know when your brake pads are worn out? Here’s what to look out for – and when it’s time to swap them out.

1. How much pad thickness is left?

Often, just one look tells you enough. If the pads are down to less than 1 mm: time to replace! New pads typically have 3–4 mm of material, so compare them.

Tip: Check the pads when your wheels are off – that makes inspection easier.

2. Scraping or squealing sounds

If you hear metallic scraping or squealing while braking, that’s a red flag. It usually means the backing plate is already contacting the rotor – not good! That hurts braking performance and can damage the rotor too.

3. Longer braking distances

If you notice you need to pull harder and harder to stop, your pads may be worn. Another clue: the brake lever feels different or “spongy.” If things feel inconsistent, check your pads.

"Brakes are your life insurance. That’s why I check every client's brake pads before each ride." – Klaus, Ötzi Bike Academy

4. Visual check: shiny surface on the pads?

Sometimes the pads are still thick enough but have developed a glossy surface due to overheating – often after long descents. Glazed pads reduce braking power and should be replaced.

Tip: You can try sanding them lightly, but it's usually best to replace them.

"On the many technical trails in the Sexten Dolomites, working brakes are an absolute must." – Arno, Bike Academy Sextner Dolomiten

Conclusion: check before every big rides

Brake pads wear out – and they’re one of the parts you should monitor regularly. Replacing them is easy and cheap – better safe than sorry!
