In this guide, I’ll walk you through the steps on how to troubleshoot and repair your mountain bike brakes. So whether you’re a seasoned cyclist or a new rider, you’ll be able to get back on the trail in no time.
Why Mountain Bike Brakes Not Working
Brake Pads Worn Out
The most common reason for mountain bike brakes not working is worn out brake pads. As you brake, the pads rub against the rotor and wear down over time. When the pads are worn too thin, they can’t create enough friction to slow the bike down.
Brake Rotor Warped
Another common cause of mountain bike brake problems is a warped rotor. This can happen if the rotor is exposed to excessive heat, such as from repeated hard braking or riding through deep mud. A warped rotor will make a grinding noise when you brake and won’t be able to stop the bike effectively.
Brake Caliper Not Adjusted Properly
If the brake caliper is not adjusted properly, the pads may not be able to make full contact with the rotor. This can cause the brakes to drag or to not work at all.
Brake Fluid Leaking
If the brake fluid is leaking, the brakes will not be able to generate enough pressure to stop the bike. This can be caused by a damaged brake line or a faulty master cylinder.
Brake Lever Sticking
If the brake lever is sticking, it can prevent the brakes from releasing properly. This can be caused by a damaged brake cable or a faulty brake lever.
Brakes Not Adjusted Properly
If the brakes are not adjusted properly, they may not be able to generate enough stopping power. This can be caused by a number of factors, such as the brake pads being too close to the rotor or the brake cable being too tight.
