What type of brake system uses a brake chamber push rod that pushes a wedge directly between brake shoes against the inside of the brake drum?
Spring Brakes
Wedge Brakes
Dual Air Brake
Disc Brakes
The correct answer is: Wedge Brakes
Wedge brakes use a brake chamber push rod that pushes a wedge directly between brake shoes against the inside of the brake drum. This design effectively applies force to the brake shoes, causing them to press against the inside of the drum and create friction to slow or stop the vehicle. Option A, Spring Brakes, are a type of air brake system used for parking and emergency brakes, but they do not use a wedge to push between brake shoes. Option C, Dual Air Brake, refers to a type of air brake system commonly used in commercial vehicles, where separate air systems operate the service brakes on the wheel ends. Option D, Disc Brakes, use a hydraulic system to squeeze brake pads against a disc rotor to create friction and slow down or stop the vehicle.
