The components found in typically brake system consist of
1 The back plate assembly
2 The brake drum
3 Wheel, nuts
Brake drums
Brake drums are made up of highly cost oil which conduct heat well and this slot away the drum rotates on its axle and wheel providing the friction surface when the brakes are applied
Back plate assembly
The drum brakes system consists of numerous components, including a stationary back plate that provides a fixed space for other components to be attached.
Brake shoes
It consists of steel frame fitted with a friction material or brake lining this material is bounded on the outer phase of shoes frame there is a wheel cylinder
Wheel Cylinder
A wheel cylinder is connected to a hydraulic system, with a piston forcing the piston outward. When the brake pedal is pressed, a shoe retaining spring pulls the shoe, while a tensioning spring withdraws the piston.
Mechanism of Drum Brakes
Drum brakes adjust by creating friction on brake shoes, reducing current movement and maintaining consistent pedal field and braking response. Hand brakes activate rare brakes by pulling up the cable, causing brake shoes to align with the drum, maintaining tension until the hand brake is released.
