As a driveshaft parking/emergency brake[edit]

Further information: Transmission brake

Drum brakes have also been built onto the transmission's driveshaft as parking brakes (e.g., Chryslers through 1962). This provides the advantage that it is completely independent of the service brakes—but suffers a severe disadvantage in that, when used with a bumper jack (common in that era) on the rear, and without proper wheel blocks, the differential's action can allow the vehicle to roll off the jack.

Land Rover have used a drum brake on the gearbox output shaft for over fifty years. The advantage is that all four wheels can be braked with the parking brake.

Disadvantages[edit]

Drum brakes, like most other brakes, convert kinetic energy into heat by friction.[5] This heat should dissipate into the surrounding air, but can just as easily transfer to other braking system components. Brake drums must be large to cope with the massive forces involved, and must be able to absorb and dissipate a lot of heat. Heat transfer to air can be aided by incorporating cooling fins onto the drum. However, excessive heating can occur due to heavy or repeated braking, which can cause the drum to distort, leading to vibration under braking.
