Advantages and disadvantages of internal expanding brake

An internal expanding brake consists of two shoes where the outer surface of the shoe is lined with some friction material to increase the coefficient of friction and prevent wearing away of the material. This type of brake is used in cars and light trucks. Let us have a deep insight into the advantages and disadvantages of internal expanding brake in this article. 

Advantages of internal expanding brake: 

  • Requires little maintenance.
  • It has a simple construction with a small number of parts.
  • It is cheaper as compared with other types of brakes.
  • It is more reliable due to the small number of parts.
  • Offers protection against the entry of foreign particles.
  • Produce a large braking torque with a small actuating force.

Disadvantages of internal expanding brake :

  • Poor heat dissipating capacity.
  • It becomes self-locking due to wear.
