About Brake Drums

Drum Brakes are the brake system that some cars have on all four wheels and others just on the rear wheels with disc brakes on the front. They consist of a brake drum which contain two brake shoes and the hydraulic system that includes a cylinder with two pistons.

The brake drum is situated behind each wheel to which it is fitted. Access to the drum is obtained with the removal of the wheel and with the removal of a small retaining screw the drum can be pulled of the centre axle revealing the cylinder and brake shoes.

The Drum Brake is operated through the foot brake, when pressed, hydraulic fluid is forced through piping to the cylinder inside each brake drum. Two pistons inside the cylinder push out horizontally pushing two brake shoes outwards to make contact with the smooth inside of the brake drum.

The drum spins with the wheel and the brake shoes are fixed, when the lining pads on the shoes come into contact with the inside of the drum the spinning speed is reduced according to amount of pressure and time applied to the foot brake. 

Periodically the brake shoes will need to be renewed as they have a pad which wears away. If this pad is allowed to wear to thin, rivets holding the pad to the metal shoe will damage the smooth inside of the drum causing damage to the surface reducing the effectiveness of the system, and if the damage is too severe will necessitate replacement of the drum. Another part which, over time fails is the cylinder which through wear and tear between the cylinder and its pistons can cause leakage of hydraulic fluid.

Mercedes-Benz trivia

• The Popemobile is a Mercedes Benz M-Class SUV. It's not a standard model, however, and has some added features like an inbuilt oxygen system and bulletproof glass.
• Mercedes Benz cars have always been a big part of the Jurassic Park films, but the first movie went all out, with the stars emerging from a red Mercedes GLE Coupe before walking down the red carpet. Mercedes cars are also used throughout the film franchise.
• Nepal had very few roads at the time, but the car company still gifted a shiny new Merc to the king of the country in 1940. It was the first car that had ever been in Nepal!
• Most people think of silver when they think of a Mercedes, but that iconic colour was an accident. Just before a race in 1934, the white-painted W25 was found to be 1kg over the weight limit. The paint was quickly removed, the weight limit reached, and the car won the race.
• Unlike most cars, Mercedes vehicles are not spray painted. Instead, they are completely submerged in anti-corrosion coating and primer. That means the protective liquid can get into every part of the car.
