Both of these can lead to very unsafe situations. In short: cleaning the disc brakes is very important. In this cleaning guide I tell you everything you need to know!

Why clean mountain bike disc brakes?
Let’s start with why it’s so important to regularly clean your mountain bike disc brakes. Although very important, cleaning a mountain bike is an often forgotten activity. And that is quite a bad thing, since not or too little cleaning of bicycle disc brakes can lead to unsafe situations.
Consequences if your bicycle does not clean disc brakes
Apart from unsafe situations, various mountain bike parts can also be seriously damaged. The biggest consequences at a glance:
- Brakes slide through: if the brake discs are very greasy, brake pads can slide on the disc brakes, so that you do not brake or brake much too slowly. And of course we shouldn’t think about that during a mountain bike ride.
- Brakes squeezing: Too much dirt can also cause your brakes to sag. As a result, you have to provide much more energy to move forward. And that is of course a sin.
- Disc brakes can be damaged: When brakes are applied, the disc brakes can also be damaged. And this ultimately affects the braking quality.
So, it should be obvious why it’s time to clean them!

Turn the wheel to make sure you apply it all over. Do this on both sides of the disc brake.
- Wipe the dirt off the disc brakes with a cloth.
Is there still a lot of dirt left behind? Then apply the degreaser again.
- Rinse the disc brake well with water after removing the dirt.
Make sure they are completely clean and don’t be too frugal with the water.

So do this with a different cloth than the one you used with the degreaser.
