What is bicycle mechanical disc brake?

Mechanical disc brakes are very common, they aren’t bad, but let’s mention some disadvantages:

  • Backlashes from friction, because the cable is constantly moving
  • Cables can stretch from time to time about once a season
  • Requires careful maintenance and constant readjustment
  • Cables are slightly springy, so braking will not be as crisp as with disc hydraulics

It’s the most primitive and budget form of braking systems, but still works properly even in cold conditions and lasts a long time with a good attitude.

Hydraulic braking is more up-to-date and there are why:

  • Less braking force
  • More responsiveness
  • Sharper braking
  • Independent of weather conditions
  • Less wear and tear because unlike mechanical disc brakes, hydraulic disc brakes have less contact area, all work is done by the hydraulic line.
  • No backlash

At the same time, a hydraulic disc isn’t perfect and mechanical can work pretty well. Let’s get to it.

How do the mechanical disc brakes work?

The mechanical brakes work like a v-brake. The most important thing is a steel cable. When the brake is pressed, one of the pads moves and presses the disc against the other, stationary but adjustable pad. 

Adjusting brakes on an electric bike

Cable tension needs a regular adjustment and electric bicycles have the same disc braking system. How to tighten brakes on an electric bike is a very common question, because after a while any brakes get loosened. Read manual carefully before the process or give it to pros.
