Most Common Reasons: Bike Front Brake Not Working
Most Common Reasons: Bike Front Brake Not Working
1. Brake Pads Worn Out
The most common reason for a bike front brake not working is that the brake pads are worn out. When the brake pads are worn out, they no longer have enough material to grip the brake rotor and slow the bike down. This can be a dangerous situation, as it can lead to a loss of control of the bike.
2. Brake Rotor Damaged
Another common reason for a bike front brake not working is that the brake rotor is damaged. This can happen if the rotor is bent or if there are grooves or scratches in the surface of the rotor. When the brake rotor is damaged, it cannot grip the brake pads properly, which will prevent the bike from slowing down.
3. Brake Caliper Misaligned
If the brake caliper is misaligned, it will not be able to apply pressure to the brake pads correctly. This can cause the bike to pull to one side when you apply the brakes, or it may not slow down at all.
4. Brake Fluid Low
If the brake fluid level is low, it will not be able to create enough pressure to apply the brakes. This can cause the brakes to feel spongy or to not work at all.
5. Brake Lever Faulty
If the brake lever is faulty, it may not be able to apply enough pressure to the brake fluid reservoir. This can cause the brakes to feel spongy or to not work at all.
