Recently, I upgraded to a Rockrider 540 bicycle. My previous bicycle (a similar but simpler model) had rim brakes, this one has hydraulic disc brakes.
On the new bicycle, the stopping power of the front brake is clearly worse than on my old one. However, the rear brake works much better than on the old one.
Does this indicate a fault with the front brake, or does it just need some use before it becomes more effective? How can I fix it and make the brake work better?
