rumpulipasjärjestelmät
Rumpulipasjärjestelmät, a Finnish term, refers to drum brake systems. These are a type of internal expansion brake used in vehicles. A drum brake consists of a brake drum, which rotates with the wheel, and two brake shoes, located inside the drum. When the brake is applied, hydraulic pressure forces the brake shoes outwards against the inner surface of the rotating drum. This friction generates a retarding force, slowing or stopping the vehicle.
The primary components of a rumpulipasjärjestelmä include the brake drum, brake shoes, wheel cylinder, and brake
Rumpulipasjärjestelmät were a dominant braking technology for many years, particularly on rear wheels or as parking
