General information

Function:
In general, two brake linings act on the drum, in other words the linings are normally pressed against the surrounding drum. The power is possibly transmitted via a bowden cable, linkage, via brake fluid or compressed air.

Advantages:

  • Low actuation forces through internal reinforcement (servo effect)
  • Option of dispensing with brake servo unit in lightweight vehicles
  • Protected against effects of corrosion
  • Low abrasion (brake dust on the rim)
  • Longer service life than with disc brakes
  • Easy to integrate in the parking brake
  • Cost effective
  • Reduced risk of glazing on the brake linings

Disadvantages:

  • Brake lining more difficult to change than with a disc brake
  • Greater sensitivity to fluctuations in coefficient of friction
  • Poor heat dissipation
  • Low thermal resistance
  • Occurrence of fading at too high temperature
