Are drum brakes good or bad?
Drum brakes can provide more braking force than an equal diameter disc brake. Drum brakes last longer because drum brakes have increased friction contact area than a disc. Drum brakes are cheaper to manufacture than disc brakes. Drums have slightly lower frequency of maintenance due to better corrosion resistance.
When should I replace my bike brake shoes?

Usually, it’s the front ones that wear faster, NAPA explains. That’s because braking shifts the car’s weight forward, which means the front rotors need to be stronger, NAPA explains. But there is a reason why rear brake pads can wear faster than expected: traction control and electronic stability control.
