OPTIMAL BT-2030 Brake Drum

A Toyota brake drum is a key part of the rear drum brake system on many Toyota vehicles. Here’s a rundown of its function and components:

• Function: The brake drum works alongside brake shoes to slow down or stop the car’s rear wheels when you press the brake pedal.

• Components:

  • Cast iron drum: This rotating cylindrical part is where the braking magic happens. When you press the brake pedal, the brake shoes press against the inner surface of the drum, creating friction that slows the wheel.
  • Wheel hub: The drum is usually attached to the wheel hub, which allows the wheel to rotate.

• Braking Process:

  1. You press the brake pedal.
  2. Hydraulic pressure from the brake master cylinder is transmitted through brake lines to the wheel cylinder in the rear brakes.
  3. The wheel cylinder pushes the brake shoes outward.
  4. The brake shoes make contact with the inner surface of the rotating drum, creating friction.
  5. This friction between the drum and shoes slows down the wheel.
