Adjusting electric drum brakes
Drum brakes are great for regulating speed. I put one on after a close call at close to 50 MPH. Drum brakes are more common on older vehicles, though some modern vehicles still use them in the rear. Drum brakes consist of a wheel cylinder, brake shoe, and a round brake drum that rotates with the wheel. Drum brakes are useful for wet or dirty conditions. They are heavier, more complicated, and frequently weaker than rim brakes, but require much less maintenance and are less affected by road conditions.
Drum brakes are not as easily service as the Disc type. You will need a wheel puller just to get the drum apart to replace the shoes(which are similar to pads). Drum brakes are still commonly seen on European bikes and particularly tadpole trikes, while disc brakes are becoming more common in the latter application here in the US. These press rubber brake shoes against the inside of the hub shell. Drum brakes are available in various models with 11.31 in. Drum brakes are capable of holding 1,000 pound-force feet to 30,000 pound-force feet torque.
Drum brakes are manufactured from cast iron and machined on the CNC turning and CNC milling / drilling machines. The drum brake works in a similar fashion to the disc brake. Drum brakes are non linear and are sensitive to small changes in friction coefficient. Disks are superior, not because they can dissipate more power but because their actuation force is entirely decoupled from the retarding force. Drum brakes are found on the rear of many vehicles. They do not use a shiny metal rotor like the disk brake design, but have a large dinner plate sized drum that is often rust colored from exposure to the elements.
Drum brakes are dying out in the sport even as cantilevers become more popular daily. There appears to be no truly compelling reason to use cantilevers save for a significant reduction in weight. Drum brakes are a type of automotive brake commonly used by almost all car manufacturers. They work to stop a moving vehicle when the driver applies pressure to the brake pedal, which pushes fluid through the hydraulic lines leading to the drum brakes. Drum brakes are old technology. Front disc brakes have been available as an option on the Mustang from day one.
Drum brakes are very different from other types of brake. Most people who are used to rim brakes will immediately think that the drums have very little power, because of their progressive performance. Drum Brakes are almost universal on heavy trucks because of the amount of surface area that can be provided and power developed. Aircraft landing gear use drum or disk brakes. Drum brakes are also less expensive to manufacture than disc brakes, and provide a simpler parking brake setup.
Drum brakes are still used in some modern cars because of some engineering and cost advantages. Drum brakes allow simple incorporation of a parking brake. Drum brakes are a type of braking system with an iron casting shaped like a shallow drum that rotates with the wheel. Curved brake shoes are forced into contact with the inner edge of the drum to provide stopping or braking power.
